Fast when you want it to be, slow when you need it to be, and always stylin'.
In the full-scale aviation world, the Very Light Jet category (VLJ) is comprised of small business jets that seat four to eight people. They give private pilots the speed to effortlessly zip past an ordinary Cessna 172 on the way to a weekend fly-in. With a VLJ, the pilot would be finished eating that $100 hamburger before the 172 even enters the landing pattern.
The design of our Raven is inspired by Terry Dunn's VLJ design published years ago in Fly R/C magazine. Although Terry's original design was a simple, foam park-flyer, it had great lines reminiscent of the VLJs that Cirrus, Sonex and others now produce - or even possibly Mooney, if they had ventured into private jets back in the day.
We based the size of the Raven around a 64mm EDF - a power system that's inexpensive, readily available, and has plenty of power for this type of design. It's mounted right up-top, in the air flow channel of the fuselage. From there, we massaged and reworked Terry's design, adding landing gear and re-engineering the fuselage to have a removable wing section. A little tuck here, a little snip there, and the Raven was born.
The Raven's wing is a snap to build. It utilizes our unique WEB-LOCK wing construction to lock in critical alignment locations. The stressed balsa skin makes the panels very light and surprisingly rugged.
We've designed the Raven's fuselage to be self-aligning, with a light-weight internal structure for added strength. Surrounding this is the outer balsa skin, which is strong, light-weight, and twist-resistant. Overall, this balsa/ply airframe is uncomplicated, lightweight, easy to build, and features precision laser-cut parts that fit together quickly and accurately.
Oh, and let's not forget that V-Tail. It's the Raven's party piece - the touch that gives it that unique look - its swagger - its style.
The wing is removable for storage/transport and for giving access to the radio/servo area. From there, you have easy access to install the radio and ESC. What's more, the fully assembled model can fit in the trunk of most cars.
Up front, there's a large hatch, which gives quick access to the battery and nose-gear. The hatch's spring-loaded latch makes swapping in a fresh pack a breeze.
When it comes time to fly, the Raven will surprise you in a number of ways: First, is the takeoff roll - it's shorter than you might expect!
Second, the Raven's wide flight envelope. It's just as much at home cruising around the pattern at lower throttle settings as it is tearing up the skies at full-throttle. Next is the Raven's surprising aerobatic capabilities. Now you'll never confuse this for a pattern ship, but Raven can easily perform loops, rolls, 1/2 Cubans, split-S, inverted flight and more - and most without needing a dive to start.
Lastly is the controllability. Even at very low speeds, you'll always feel that you have control of the Raven. And that controllability is a welcoming feeling when it comes time to land smoothly, slowly, and right down the runway.

Please note:
We've done everything we can to make the Ravem a fun and easy to assemble kit. That being said, THIS IS NOT A BEGINNER KIT. If you've never built this type of balsa kit before, you will probably experience many challenges along the way. The manual is not written for beginners - it is assumed that the builder has the skills and techniques needed for this type of build.
Due to high demand, allow at least 2 weeks or more for shipment.
Did you ever get to see a Wright Flyer fly? Did you ever dream that someday you'd get to wiggle the wings on a Wright machine? I'm betting during all those many months of testing, planning, designing our famous Wrights went to bed wondering what it would be like. Then they did it. Now, you can do it. This conversion kit combined with the parts from two GWS Slow Stick slope glider kits (no longer available, discontinued by GWS) will produce a sport scale 1905 Wright Flyer. This model from the side view is scale having all the struts the original had. Omitted are all the flying wires and control cables. All the fiddly bits included on a perfect scale model (that break every time you land one) are gone. My intention was to design a model you could fly 10 times in a day if you liked and not once or twice a year for special occasions as you'd probably choose to do with a pure scale model.

How does it work? If you look close you can see our unobtrusive elevator servo (we used a GWS Pico) on the canard support strut. This servo drives the top canard which in turn, drives the bottom canard through a simple transfer rod. The canards move up and down together on thier own individual pivots like the original 1905 flyer. The rudder servo is adhered to the bottom of the bottom wing with a Dubro Micro Push rod (1/32 wire in clear plastic tube) driving the rudder. The rudder moves like the original 1905, both together. Perhaps the most exciting feature is this model flys with real wing warping. The outside wing strut assembly has a servo hidden under the bottom wing driving a diagonal rod that appears to be a simple bracing rod in the scale location. Forget the Eindecker like wings, wouldn't it be gross if this model didn't turn by real wing warping? You're going to love this feature every time you show how it works.
How does it fly? I was amazed, after some initial hiccups working out the right setup. We've refined CG and throws until it flies more or less like you'd expect a trainer to fly. It is a bit draggy so you tend to fly with a middle throttle position most of the time and you will want to be comfortable flying with both hands as this design likes rudder inputs. However, you'll soon agree it flies like a trainer. Provided in the kit is the CG you need along with servo horn lengths, control throws and even exactly where to trim the canard for that first flight.
How does it build? This is not a normal kit, it's mostly nut and bolting with some foam trimming and fitting here and there a little gluing and some finishing (staining). If like me, your favorite ever childhood toy was an Erector set, you're about to feel young again! Now I know you hated those square nuts and slot head screws (I did) so we included all hex wrench driven button heads and ny-lock nuts. There is a surprising amount of aircraft ply in this kit. The main structure starts out as a 24"x24" section of 1/8" thick air ply (cuts slower on a laser) and it's packed tightly with many parts. Needless to say, there is a lot of laser cutting time here. It has the longest hardware list of any kit we've ever designed and the longest instruction set I've ever written including several drawings/templates. Ron, who built both of our in-house prototype models said he needs 3 work days to complete one. So, please plan enough time, it's very important to us that you actually finish it and get it flying. I want to hear the joy in your voice and see the pride on your face when you tell me about it at the next show.
Whats included? All the hardware needed that isn't already in the Slow Stick kits is included here. All fasteners are good quality allen head bolts with lock nuts. There are 88 washers and you can guess how many nuts and bolts.
What do you need to complete? Add 2 motors (max 2oz, 800-1200 KV), 2 stick type motor mounts, 2 ESC's, APC counter rotating prop set, electronics (2 each 6 gram servos, 2 each 20oz torque servos (we used HB-65's), and 1 each 3S battery 1800-2200mah. Extensions and Y's. For motors under 1000 kv, use 10-4.7 props, 1000-1200 kv use 10-3.8 props.
Need repair parts? Get 1/2 a wing mount set here. The riser is the vertical leg set (4 parts) that fix the distance from boom to wing mount surface. The Perch sets dihedral angle, is the mount surface, rubber band pegs, and the horizontal parts that fit between the risers to form a box to slip over the boom. SKU Number: RRCSSWMPARTS****
Warbird Main Gear Mount. Most any WWII Theme model you build will need the main gear mounted to the wing in order to look right. (Can you believe what I'm suggesting? ;-) ) Shown here used on our shop Wart Hog theme model.
Like many of our parts, this one may be reconfigured easly by simply flipping parts for tail dragger or tricycle configuration. Tricycle shown. 3/32 Music wire (Part# KS506) was bent to shape, bend any height you want. Wire may come down from inside or outside edge of mount to allow for a variety of gear widths depending on the look your going for. Suggest wheels collars Part # DUB138 to hold your wheels on.
The Slow Stick wings and glass fiber rods support both front and back where we have it banded on in the photo. Takes landing loads quite well. The look generated along with your likely use of low wing moutning set and aileron kit (both available in this category) will have everybody thinking you must be flying some new just released super model.
If you've grown comfortable with our Micro Stick, perhaps you are ready for the Micro Bipe. This aggressive little beast does not know it shouldn't be able to fly. Kit comes with all the parts required to build with the large top wing (13.8" span pictured) for intermediate pilots or the small top wing (only 10.8"!!!) for the bolder more advanced pilots. Comes complete with pushrod wire, horns, rod end keepers, landing gear wire and wheels.
Suggested (not included) components are Medusa 12mm 4000kv outrunner, 2-3 6g or smaller servos, Micro RX like Berg 4 (sub 10 gram), 350 to 760mah 2S HD lipo pack, props to suit motor with adapters and lots of testosterone! She can be tamed quite a bit with the large top wing but we warn you; she's pure aggression with the small top wing. Build her wisely!
If you select a 72mhz Berg receiver (RX), tell us which channel you need at checkout.
The Micro Bipe weighs in at 4.5 to 5.5 ounces depending on equipment choices. Kit exhibits our new ultra-rugged Space-Frame doublers and inline Formers, both Radical RC innovations in the RC Kit Field. Like most of our kits, 90% of it may be assembled prior to gluing due to the close fit of the lazer cut parts.
If your thinking of other motor, mini outrunners & etc., the requirements are 30 watts plus and 50mph pitch speed or more. Only the smallest lightest motors should be considered.
Additional photo showing both Eindecker and Sport versions. Either version can be built from the kit. The TX is shown in photo to demonstate scale only. (Note, manual and above recommendations are now outdated and similar products should be substituted.)
* Asterisk items are Our first and favorite picks. All items listed are good choices.
The Medusa 4000kv on GWS 3-3 prop is my all around favorite setup. A 4-2.5 prop may also be used for less speed and better climb on the 4000kv motor (Requires adapter to 4mm prop). Optionally the RRC 4500 on 3-3 is also good. For more extreme performance, the Medusa 5300 on 3-2 or 3-3 prop and 2S battery. Be sure to get the Fox Lite mount for any 12mm motor. The 3" GWS props press directly onto 1.5mm shaft motors, the 1.5mm reamer is suggested below to ease pressing on the prop. 1.5mm motor shafts are more easily bent, 2mm shaft motors are also offered. They require drilling the prop out with a #49 (.073") bit and have more rugged shafts.
The Stevens AeroModel SQuiRT provides a solid platform for your student pilot to learn on. Speed 400 Primary Trainer for 3ch. Simple one evening construction allows you to get airborne quickly. Innovative shock absorbing gear and wing mounting system make crash damage exceptionally rare. In-fact, we have found this model to out perform any foamy in it's class in terms of flight performance and ruggedness. Rugged doesn't have to mean overweight as our 38" span Squirt weighs in at a lean 13.5-14oz with a 1500mah lipo and well under 16oz with a KAN 650 7 cell NIMH.
Thoughtful design and innovative beginner friendly features abound. Tab and notch construction makes building a straight and true wing and fuselage as easy as pouring as gluing your fingers together! The kit includes a full hardware pack loaded with high quality Du-Bro hardware, Wheels, Full-Size Plan Sheet, Pre-Bent Landing gear, a detailed step by step photo illustrated instruction manual, the kit even includes an excerpt on primary aerobatics derived under license from the RC Pilot Guide written by Scott M. Stoops.
Flying the Squirt is a great pleasure even in windy conditions that will send the other slow fliers packing. Additionally, the positive stability of this model allows the instructor to trim for level flight and hand over the controls to the student pilot. If the pilot looses control all that is necessary to regain control is reduce power and center the sticks - The Squirt will rapidly return to level flight!

Some of the above setup suggestions may be outdated, look for similar up to date items.
Light Kit made perfect to fit your Slow Stick or other similar sized models up to about 46" wingspan. Wires long enough to install with tape on bottom of wing surface allowing lights to hang couple inches off the wing tips, elevator and motor mount. As such they are easily seen from many different orientations in the sky. 4 LED Setup, 1 red for left wing, 1 green for right wing, 1 white for tail and 1 yellow for nose. Aproximate draw is only 85mah.
Our light kit simply plugs onto your XH balance connector on your 3S Lipo pack. XH is the most common plug as found on Radical RC, E-Flite, Align, Dualsky, Electrifly, Tenergy and many others. No soldering, just plug them in and head for the stars.

Estimates based on manufacturers provided constants using E-Calc. High Quality 2100-3000mah used as trial cell in calculations. Presumed model weight of 76oz. @3 cells (added oz for higher cell counts). Actual performance may vary depending on components used, accuracy of data as provided by manufacturer, quality of battery, ESC, and many other factors.
Excited to get these out again so you can show the ARF pilots how bad they are missing out!
This model is outstanding on any 400 class outrunner in the 980-1300 KV Range, 3S packs from 700-1300. Think of props from 8-4 to 9-6 depending on KV. 70 to 170 watts is the right range. The model is strong and roomy enough for 300 watts if your desire are of the insane variety.
My favorite setups so far: Himax 2816-1220, 9-4.5 prop, 3S 1300 Kypom 35C K6 series. Around 19 amps, about 240 watts. Himax 2812-650, 9-4.5 prop, 5S RRC or Kypom 450. Less than 10 amps! About 165 watts and super effiecient. GWS 003 Outrunner, 8-6 prop, 3S 600-1300 size 3S pack.
Many systems will work well here. This model is a supurb sport aircraft, probably the best I have ever designed. I know it's going to become the most popular kit we've ever made. Kit comes with both Sport and Stick type flying surface options. Push button wing release, space frame formers/doublers, one or two servo ailerons and simple zip tie on landing gear are standard features.
This model is everything you expect a Stick to be and everything you expect in a Radical RC kit. Construction is fully interlocking and completely self jigging. It is actually possible to build 90% of the kit prior to applying any adhesive. In fact, most of the assembly is squeezing together friction fit -n- tab self jigged assemblies and applying thin CA sparingly at the conclusion of each assembly. Fit is so good, only the most minimal amount of sanding is needed prior to finish application.
Model is designed specifically for E-power. Predrilled firewalls are included as are blank firewalls and a more short nose mounting location if you want to go 1/2 A glow. And, it's not needed since you finished glow flying weight will be about 14-16oz on glow. Model is expected to finish 13-18oz. One of my samples weighs in at 16oz. the other at 17oz. Normal weights for high performance sport aircraft with these capabilities and landing gear is 24oz or more.
Instructions include complete breakdown on motor system choices and theory for this model. Because it's so light weight, you can have a legitimate 2S system here. Our prototypes are flying on 3S (foreground) and 5S (background).
Model is built with conventional 1 or 2 servo - 2 aileron wing. May be upgraded to 3D surfaces with our optional 3D Surface Kits. With 3D Surface Kit you can run 2 servo big ailerons or 4 servo split aileron/flaperon combo. Expanded surface for elevator and rudder included as in photo. Note, the 3D Surfaces Kit only works with the "Sport" Vertical Stab.
An easy-flying 2-meter glider for when you want to slow things down for a while.
Whether you prefer power-assisted take-offs, high-starts, or slope soaring, this easy-to-build glider is the perfect way to spend a lazy afternoon.
We've gone the extra mile to ensure that the Wayfarer is as easy to build as it is to fly. There's a wealth of laser-cut balsa and plywood parts that go together straight and true. Laser-cutting even extends to the wing sheeting giving you the perfect fit.
A wing that is 2-meters long can be tough to transport so we've designed the Wayfarer's wing as two, plug-in panels.
As a bonus, we've also included all the parts needed to make the removable power pod.
Radio: o 2-3 channel system o 2, 40-70 in./oz. mini servos o 3s 2200mah
Power: o 2204/2206 sized brushless motor, 5" prop, 25amp esc
WEB-LOCK Construction There's nothing else like it. Build our wings, straight and true - with a minimum amount of fuss.
Premium USA Hardware Included in each Old School Model Works kit is a premium hardware package. We only source our hardware from brand-name, USA manufacturers to guarantee the best quality.
Power Pod If you choose to launch via motor assist, we included all the pieces necessary to build this removable power pod.
Battery hatch Held in place with thumbscrew, this hatch gives you easy access to batteries.
Additional items needed to complete the Wayfarer kit: o 2-3 channel radio and servos o Propeller o Motor mount & mounting hardware o Pushrods (two 24") o Clevises for the pushrods o Covering

Trainer-like stability. Sport-Pattern performance. Quick and easy to build. What's not to love?!
Designed as a first low-wing trainer over five decades ago the Lark is still a terrific, everyday sport plane. OSM's version of the Lark keeps all of the iconic looks and great flying characteristics of the original. Plus, because it combines docile flight characteristics, trainer-like stability and an aptitude for super-smooth, exciting aerobatics, the Lark is just what you need to step forward with your flying ability.
OSM's kit has been designed to keep building time to a minimum and introduces new, simplified building features as well as laser-cut precision and self-aligning parts to make this all-time favorite even better. Building the wing and stab are a snap as all of the ribs include tabs which allow you to quickly and precisely align them on your building board. Did we say stab ribs? Why yes we did, as we integrated the original airfoil shaped stab into this design as well. The fuselage is built around a self-aligning, light-weight box for added strength. Surrounding this is the outer balsa skin that is strong, light-weight and twist resistant. Importantly, this balsa/ply airframe is uncomplicated, lightweight, easy to build, and features precision laser-cut parts that fit together quickly and accurately.
Power can come from glow or electric powerplants. We've designed the fuselage with a magnetic top hatch so you have quick access to either your fuel tank or batteries.
In the air, the Lark is an aerobatic, yet forgiving design that makes it the perfect entry-level low wing airplane. It's also great for experienced pilots because it packs a fully aerobatic capable design into a small package that can fit in the trunk of many cars, completely assembled.
When flying at slower speeds, it's a great way to relax, shoot touch-n-goes and enjoy low passes down the runway. But throttle it up and the Lark is just at home as an entry-level sport-pattern ship. Loop it. Roll it. Thrown in some Cuban 8's and even some hammerhead turns for fun and you'll enjoy every minute of it. This Old School Model Work's Lark is a Vintage R/C Society legal design for enjoying vintage fly-ins and contests.
Features: Premium USA Hardware Included in each Old School Model Works kit is a premium hardware package. OSM only sources their hardware from brand-name, USA manufacturers to guarantee the best quality.
Interlocking Construction There's nothing else like it. OSM's interlocking construction allows you to assemble the entire airframe with a minimum amount of fuss.
Front hatch Securely held in place with magnets, this hatch gives you easy access to batteries or fuel.
Build as Glow or Electric power Power the Lark with either a glow or electric powerplant.
VRCS legal kit OSM's Lark is a Vintage R/C Society qualifying design making it eligible for vintage/retro events.
Power: o Glow (.25-.40 engine, 4-6 ounce tank, fuel tubing) o Electric (equivalent brushless motor - 550+ watt, 40+ amp ESC, 3-4S LiPo)
Photos include shots of the Lark prototypes in various stages of construction and one of OSM's electric powered Lark prototypes finished and in flight.
Additional items needed to complete the Lark kit: o Propeller o Engine/Motor mount & mounting hardware o "Y" servo harness (for ailerons) o Pushrods (two 5" for ailerons, two 26" for elevator & rudder, one 14" for nose gear, one 10" for throttle if glow powered) o Clevises for the pushrods (10 if electric, 12 if glow). o Wheels: one 2.25" nose, two 2.5" mains o Covering (typically 2 rolls) o Optional 2.25" or 2.5" spinner
Due to high demand, allow at least 2 weeks or more for shipment.
Fast, but not too fast. Maneuverable, agile and responsive - but not tricky. A snap to build - and with a fully sheeted airframe, surprisingly rugged compared to most.
Don't let the lack of landing gear scare you. Hand launching is easy because of the fuselage's light weight and strengthened design. In the air, it really looks the part without any exposed gear to detract from it's clean lines. Bringing the Fifty-One in for a belly landing on grass is just as easy.
You should see them take evasive maneuvers in Dog Fighting. Evade with snap rolls into spins, Immelmann turns and a loop.
OSM's Fifty-One kit is part of our Sunday Fighter lineup and just might be the most fun you've had in a long time.
Because of the interlocking design and high quality laser cutting of the parts, the Sunday Fighter is a quick build. Not only does it build quick, but it also builds straight and true as all of the parts are designed to align properly with a minimum of fuss and alignment tools.
The wing is removable for storage/transport and for giving access to the radio/servo area. From there you have easy access to install most any brand of radio and control linkages.
What's more, the fully assembled model can fit in the trunk of most cars.
Although mainly designed for electric power, you can also use a .25-sized glow engine as well. Glow engines are side mounted. Electric motors are mounted on the "extended" firewall to space the motor the proper distance forward. When assembled, you now have a blank canvas and can apply any number of color schemes, or make up your own. In the air, the Fifty-One is a blast to fly. A simple hand-launch gets it airborne, then you can cruise quite easily and 1/2 power. Throttle up for loops, eights, snaps, spins, hammerhead turnaounds - or maybe a screaming low-level pass, right down the runway. When you're ready to land, simply throttle back and gently bring the Fifty-One in for a belly landing on the grass.
This is just one design in our growing Sunday Fighter series. Specifications: Wingspan: 44.5 inches Wing Area: 330 sq inches Length (airframe only): 39 inches Weight: 3 - 3.5 pounds Radio: 4 channel system Power: o Glow (.25 engine) o Electric (350+ watt, 60 amp ESC, 3-4s LiPo)
Features: Premium USA Hardware Included in each Old School Model Works kit is a premium hardware package. We only source our hardware from brand-name, USA manufacturers to guarantee the best quality. Dual Ailerons Mounted under the lower wing, these two pre-cut aileron hatches make it easy to install the aileron servos. WEB-LOCK Construction There's nothing else like it. Build our wings, straight and true - with a minimum amount of fuss. Battery compartment Perfectly sized to take 3-4s 2200 lipo packs, plus an ESC. Open design makes batteries easy to swap out, and keeps the components cool. Under-Fuse Air Scoop Just like the full-scale, our Fifty-One has a scoop under the fuselage. It's held in place by the wing bolts. Fly with or without it - your choice.

Jet-like looks and wide flight envelope make this design stand apart.
Had enough of the same old designs? Need a ship that is new and different? Look no further than our Polaris - unique, easy to build, and exciting to fly!
We've taken Bill Evans' original and brought it up-to-date.
Included are new, simplified building features as well as laser-cut precision and self-aligning parts to make this all-time favorite even better. For example, our exclusive Web-Lock construction makes building the wing panels a snap. Rather than the sheer webs being an afterthought, they are utilized during the build to properly space, position, and lock in each rib.
This type of design is commonly referred to as a Simitar. Though Simitars operate on the concept of a flying wing, they don't really look like a flying wing, nor do they appear to be conventional in nature. So, what makes them different?
First, no stall. Reduce power, gradually feed in up elevator, and as it slows down, the nose will automatically drop a bit, reducing the angle of attack; therefore, no stall. What makes this possible is the innovative ESA (Evans Simitar Airfoil) which is a semi-symmetrical reflexed design.
Next, the wide speed range. No matter how much power you put into a ship from the Simitar Series, it goes faster (no Dutch Roll). It also slows down to a crawl (the effect of no stall) and sets down like a hang glider.
Finally, a Simitar is directional in flight, in that it will remain in most any attitude it is set in. Once properly trimmed, point it in a direction, and rest assured, it will do as commanded.
Join the Simitar Squadron and become a Polaris pilot with a design that's very smooth-flying and graceful. Easy to build with pieces laser-cut from high-quality balsa and ply woods. When finished, the Polaris' typical Simitar characteristics give it no stall, a wide speed range, and it goes exactly where it's pointed. Our Polaris was independently reviewed by MBMrc. Check out their pre-flight video report.

At last, an easy and low cost high performance Slow Stick Twin. Gone are the days of strapping a heavy boom to the bottom of the wing with the resulting up thrust and poor handling. You can have a twin and have it fly correctly! With the Radical RC twin conversion kit you can make any Slow Stick into a twin. You can even make it into a 4 engine WWI Faux Bomber if you wish (with 2 kits). Our kit does not alter your wing in any way, attaches with simple rubber bands so you can always alter or return to a prior configuration if you like. Optionally; cut the tail off this mount and glue them into your wing for a permanent band free installation if desired.
Each kit comes with 2 mounts and high quality socket head fasteners.
For those wanting to configure a forward looking still or movie camera setup without prop interference, you've just gained an excellent option.

Our Comet captures all of the jet-age looks and excitement of the sleek 1950's design it's based on. With the included jigs, this delta wing can easily be built by those with experience in constructing built-up kits. Please note that this is NOT a beginner's kit - it requires building and flying experience to be successful.
Flying the Comet is a blast. It's not overly quick and has pleasing flight characteristics that make it fun to fly. Even at low speeds it is well behaved and has no surprising tendencies. The Comet can be powered with either an electric or glow powerplant. We've designed the fuselage with built-in hatches so you have quick access to either your batteries, fuel tank & radio system.

Historically, the full-scale Smith Miniplane is one of the designs that helped start the modern homebuilding era. Originally designed and built in 1957 by Frank Smith of Fullerton, California, the Miniplane was an early example of engineering with the amateur homebuilder and weekend pilot in mind. It could be constructed with tools easily within reach of the average craftsman, and in the air it was stable and easy to fly. The top wing spanned 17 ft., and the empty weight was a mere 600 pounds. Powered by a 100hp Lycoming, the tiny Miniplane cruised at 120 mph, climbed at a fantastic 2,500 ft. per minute, and was highly aerobatic. It was just what many sportsman pilots were looking for!
R/C Sport Scale BiPlane
In 1974, Glen Sigafoose, then President of Sig Mfg. Co., acquired a complete Smith Miniplane to use for aerobatic practice. Glen's beautiful red, white, and black aircraft was the inspiration for this mini version of the Miniplane.
FREDe(TM) (300) is a ToonScale(TM) version of Eric Clutton's F.R.E.D. (Functional Runabout Experimental Design) FREDe's airframe frames quickly thanks to precision laser cut components and simple yet thoughtful engineering. This rugged design features our shock mounted landing gear system and soaks up all the bumps and bruises a beginner can deliver. FREDe dishes out stable predictable performance with pro pleasing "fun" on tap allowing for all rudder, elevator, throttle aerobatics including flat and falling leaf flat spins! FREDe - because flying should be FUN!

The Barracuda is designed around the current (2025) E2K club racing rules, but we also found that it makes a fantastic everyday sport plane with a wide flight envelope.
The overall design meets and exceeds the E2K sport racing specifications for wingspan, wing area, and various fuselage measurements. It's a grassroots, low-cost form of racing that puts the emphasis on the pilot - not on how much the pilot can spend.
Click here to download a copy of those rules and see you can use them to hold your own club races at your field.
All of this comes in a great-looking design that is remarkably easy to build, thanks to our innovative design techniques and precision laser-cut parts.
We kept the parts count low so you can build it quickly. Believe it or not, you can go from box to full-framed up in one weekend - with time to spare! Because of the interlocking design and high-quality laser cutting of the parts, not only does it build quickly, but it also builds straight and true as all of the parts were designed to align properly with a minimum of fuss and alignment tools.
The wing is removable, giving access to the inside of the cabin area. From there, you have easy access to install most any brand of radio and control linkages. Up-front, we've designed in a large hatch that covers the battery compartment. This area will easily handle 2200mAh 3s and 4s packs.
All framed up, the Barracuda weighs just under 12 ounces, and the Barracuda's construction gives it surprising rigidity to handle most anything you can throw at it.
For club racing, pop in a 4s, 2200mAh pack and tear up the sky. Challenge your club members to see who can get the best time.
But there's more to the Barracuda than just speed. It's a very capable aerobatic design as well. Loops, rolls, inverted flight, Cuban-8s, split-S, and more are all within its capabilities.
And after you're done tearing up the skies, throttle down to easily cruise around the field. Then when the time's right, set up for a nice, controlled landing. The Barracuda's efficient airfoil gives it a good glide ratio, which makes setting up for a landing less stressful than you might think.
When it comes time to land, by design, E2k racers are belly landed on grass. Because we designed the fuselage from a strong, lite ply base, it takes the worry out of damage to the Barracuda each time you touch down.
But I know what you're asking now. "What if I don't have a grass field to land on?" We also offer a skid pack for the Barracuda, which easily bolts on to each side of the fuselage. These replaceable skids allow you to land on rough and paved surfaces without damaging the Barracuda's fuselage. A pair of skids weighs just 11.4 grams, so they have zero impact on the C.G. or on the Barracuda's flight performance.

Slow Stick Canard made easy! This all-in-one unit will mount your horizontal stab and allow angle of attack adjustments to suit your special setups. Most canards should be set to between 3 and 5 degrees positive. Range of adjust ment is from 0 to 7 degrees positive. Elevator servo moves with the canard mounting surface so your elevator adjustment stays the same relative to your canard when you alter the angle of attack setting. Mount has built in nose gear block and nose gear steering servo mount. All holes are predrilled. Includes high quality socket head hardware needed to complete.
My personal Slow Stick Canard is a twin tractor. I have a 1000mm boom length and the CG is set at 1-1.25" in ffront of the main wing leading edge. I have never built one with a stock boom length (800mm) but I would start with the CG in the range of 0-.5" in front of the leading edge. The shorter the boom the further the CG comes back, the longer the further forward you would place it. I don't know where Bob Masterson's CG is set but I would thing it is similar to my 1000mm boom setup.
Maiden Flight Video of Bob Masterson's converted Canard Slow Stick. This model is full house with 10" extended boom length.
Finally it's easy to convert to a T tail. Complete with washer plates. Glue to your stab and horizontal or use 4-40 nylon bolt/nuts in the pre drilled holes. May also be used for mounting verticals to the ends of your stab. Works with any 5mm foam. If using with stock Slow Stick parts, trim the top of the vertical down until you have a flat spot long enough for this mount. Comes complete with washer plates to prevent bolt damage to surfaces.
Slow stick parts come in both 4 and 5 mm. 4mm is .157" or pretty close to 5/32". 5mm is a little over 3/16" at .197". Measure your parts before ordering. One images shows part being used to mount a fin to the center of the wing on our Twin Tractor Canard model in the shop.
