Robart has taken the industry standard into the digital age with the Model Incidence Meter - Version 2.
Simply download a leveling app from either the app store or google play on to your smartphone. Mount your cradle (404C) to the meter bar. Mount the appropriate arms to the bar and start determining your incidences.
This incidence meter is a must for setting proper thrust and wing/stabilizer incidences on a new model.
An all-around classic that flies as great as it looks.
Imagine an easy-to-build kit that has outstanding high-speed performance as well as dependable low speed stability. Now imagine it in a great looking design and you've just described our Javelin. Bolt on a .25-sized engine and enjoy gentle flying and barnstorming. max it out with a .51-sized engine and tear up the skies with high-performance aerobatics. 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.
Because of the interlocking design and high quality laser cutting of the parts, the Javelin is a quick build. Not only does it build quick, 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 Javelin utilizes a first for OSMW kits - a built-up main gear box. This is extremely strong, yet lightweight at the same time.
The extra large cabin area gives you easy access to install most any brands of radio and control linkages.
Up-front, we've designed in a large hatch that covers the spacious battery/tank compartment. This area will easily handle larger 4s packs and 12 ounce tanks.
Whether you choose to power your Javelin with electric or glow power, we've got you covered. The firewall comes pre-etched with markings to aid in the mounting of the included motor mount. Glow engines can be mounted upright, side, or even inverted with little modification necessary.
Radio: 4 channel system Power: o Glow (.25-.51 engine, 6-10 ounce tank, fuel tubing) o Electric (equivalent brushless motor, 3-4s LiPo)

Based off a 1980's classic, originally offered by World Engines.
The Robinhood is a fun-scale version of the Curtiss Robin built back in the 1920's Originally marketed through World Engines, this model retains all the good, clean looks of the original and retains all the great flying characteristics that make a good sport airplane.
In the air, the Robinhood 25 is a true barnstormer. Don't mistake this for a 3-D hovering machine and resist the urge to overpower it. The Robinhood 25 is at it's best when cruising on a lazy afternoon or performing some gentle aerobatics. Also, no problems with mown-grass runway takeoffs and landings.
If you want to go truly "old school", it can be built for simple 3-channel control (rudder, elevator and throttle). For even more control, the included ailerons can be made fully functional (4 channel control).
The Robinhood can be powered with either an electric or glow powerplant. We've designed the fuselage with a built-in hatch so you have quick access to either your batteries or fuel tank.
Struts were a necessity on the full-scale Curtiss Robin, but are optional for the Robinhood 25. Instructions are included on how to implement them if you'd like to give your Robinhood 25 a touch of Old-School elegance.

3 or 4 channels You decide - go true "old-school" with 3 channel control, or opt for functional ailerons (4 channel).
WEB-LOCK Construction There's nothing else like it. Build our wings, straight and true - with a minimum amount of fuss.
Bolt on wing Staying true to the original, we have replicated the original bolt-on system for the wing. Front hatch Held in with your choice of screws or magnets, this gives you easy access to batteries or fuel.
Optional Wing Struts You choose. Create a set for scale looks, or fly without them for a streamlined change of pace.
All Old School Model Works kits feature:
Precision laser-cut parts Included in every Old School Model Works kit are all the wing ribs, fuselage formers, and other wood needed to build the aircraft.
Interlocking parts We've engineered each kit to give you the best chance of success. Each laser-cut part interlocks with the next for an accurate and secure joint.
Rolled Plans Each of our kits contains a set of rolled plans, never folded. They are full-size, highly detailed, and computer-drawn for accuracy.
WEB-LOCK Wing Construction Our exclusive wing design and construction techniques give you everything you need to easily build a straight and true wing with a minimum amount of fuss.
Due to high demand, allow at least 2 weeks or more for shipment.
A 4 pack of Neo Super Magnet Discs. Size: 5/16" Dia. x 1/16" Thick. Same magnets used in our Radical RC kits to hold hatches, wing latches and wings in some cases. Great for creative mounting of many things, even canopy's. The screw and rubber band were invented a long time ago. Eliminate the old time "think" of many of today's models and go fastener-less wherever you can. Lightly scuff the surface of the magnet where it's to be glued and use epoxy as your adhesive. CA is not recommended as it tends to let go of the magnet after a short time. As an extra bonus your new magnets come in a handly reusable container. You can link/snap them together to form your own sorter bin for small parts.
Arming Switch Plug for ArmSafe. Will also fit Radical RC flush mount for Deans Ultra. Spare ArmSafe® Arming Plugs. Always make sure that ALL is safe before plugging in the Arming Plug. An Arming Plug is required to energize a RC Model by plugging it into the ArmSafe® Base. The Arming Plugs are very compact and aerodynamic, when plugged in they only measure about 0.28" x 0.5" x 0.5". Weight is only 3.7 grams.
The ArmSafe® System was created to improve the safety of electric RC models by giving the user better control of WHEN they energize and de-energize their models. This control can help reduce the risk of propeller strikes due to inadvertent motor starts. ArmSafe® is an effective solution for reducing, not eliminating, the risk of injury around high powered electric models. When ArmSafe® is CORRECTLY USED, the user has better control of WHEN they energize and de-energize their RC model. Uses Deans® Ultra Plug® Pat# 5,533,915. It was developed to have all the features RC modelers want:

BadAss Motors are built from the finest materials available, and set new standards for Power, Quality and Performance that discerning modelers will appreciate. These Premium-grade motors will bring out the full flying potential of any R/C model Aircraft.
Starting from a blank slate, Lucien Miller, CEO of Innov8tive Designs, set out to design the finest motors for the R/C aircraft market. Using the best materials available, such as hi-temperature N52 curved magnets, hi-temperature copper wire, high efficiency Kawasaki stator laminations, 7075 aluminum alloy and high-quality bearings, these motors truly live up to the name "BadAss". If you're tired of cheap motors that don't last, or motors with a complete lack of performance information (we call them mystery motors), then we think you're going to appreciate the new level of power, performance, and quality that BadAss motors offer.
Our performance charts are the most extensive and complete available anywhere. The specifications table included on each motor page is also very complete with all the information you may need to know about a motor. A full set of CAD drawings is also available for the motor, prop adapter and cross mount, allowing you to check the physical fit in your aircraft before you receive it. With all this information, it is easy to make an informed decision and purchase the ideal power system for your model every time.
BadAss motors provide multiple options for mounting a propeller. Included with each motor is the standard bolt-on style prop adapter, which works for most applications. An optional extra-long bolt-on prop adapter is also available if you are using a prop with a thick hub along with a spinner with a thick backplate. Both adapters come with a standard hex nut and a Ny-Lock hex nut, for modelers that prefer the security of a locking style nut. Also available is the optional Bolt-on Smooth Shaft prop adapter. This part allows you to use a collet style prop adapter, folding prop hub, or aluminum spinner with integrated collet adapter on your motor without having to move the shaft. A full line of replacement parts is available to keep your BadAss motor in top shape for years to come.
Once you see how motor information should be presented and experience the exceptional build quality and performance of BadAss motors, you may never buy another "Mystery Motor" again. Let us show you a better way to select a power system, and we believe that you will become a BadAss Power Systems customer for life.

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.
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. 8 LED Setup. 2 red for left wing, 2 green for right wing, 2 white for tail and 2 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.
12 pack #8 laser cut aircraft ply washers. 1/64" thick (Aproximately .016" or .4mm), OD .500", ID .167". Use in many applications such as wing hold down bolts where a softer washer is often desired. Use for shimming motor mounts, servos and anyplace fine thickness adjustment is needed. Work well with metal and plastic fasteners. SKU Number: RRCFWW8X164P12
Quality foam tape, super sticky on one side, cuts down vibration. Ideal for wing saddles. 1/8 (3.1mm)H X 3/8 (9.5mm) Wide X 3 ft (.914M) per roll.
DU-BRO Foam Tape is a must-have accessory for RC pilots, drivers, and hobbyists who want a simple and reliable way to reduce vibration on electronics safely. This high-quality, sticky one-side foam tape is designed to absorb vibration and provide a strong hold, making it perfect for mounting under these surfaces to reduce vibration on items such as receivers, gyros, batteries, switches, and other sensitive components inside your RC model.

We can hand make pigtails to almost any specification. A "pigtail" is a wire with only one connector. Use to repair servos, switch harnesses or perhaps add to existing servos for that "Extension Free" custom installation. Choose from drop down menus your preferences. Generally we size these by measuring from the back of each connector. So the overall length will be greater by connector shell length. Twisted wire can be adjusted slightly in length by changing the number of twists. We try to get within about 1/2" of your spec. Please order long enough to compensate for minor variance.
Note: 2 wire battery pigtails in 6", 3 wire pigtails 10" and Micro Lite at 5" are available in machine made sizes and at lower cost, find them in the connector category to fit your specific brand. Check there first to see if any stock sizes will meet your needs.
Micro Lite: This type of wire is used most commonly in applications with small servos (.5 oz weight or less usually) in park flyers, foamies, sailplanes, DLG's and other models with low servo loads. You can save a bunch of weight eliminting beefy stock wiring from these smaller models.
26 Gauge Standard: This wire is what you find in most new radio sets and on most mid size to full size standard torque 4 screw mountable servos. This ribbon wire size is a good wire choice for those types of servos (and smaller) if the runs are 24" or less. Good for smaller servos in long runs such as sailplane wings and similar. For example, great for you 60" cub but use 2o gauge your outfitting a 100" Cub.
22 Gauge Heavy Duty: Use for all larger models and anyplace a high torque or digital servo might be used. Use for standard torque servos if your runs are very long (over 24")
Sometimes it's hard to tell the boys from the girls. Servo and battery ends are "MALE", RX's and Y harness receptacles are "FEMALE". When the pins are hidden, connectors are gendered by the shell. Just remember as an "assembly", a servo or battery plug fits inside an RX or Extension therefore it's male.
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.
12 pack #6 laser cut aircraft ply washers. 3/32" thick (Aproximately .098" or 2.5mm), OD .475", ID .144". Use in many applications such as wing hold down bolts where a softer washer is often desired.

An easy-to-handle, quick-building, great-looking design that's quite aerobatic.
The Sport Air 40 stands out as one of the more visually appealing aircraft in the 40-size market, thanks to its clean lines and striking resemblance to several full-scale light aircraft.
This excellent all-around sportster will attract many favorable comments at the flying field, not only because of its good looks, but also because of how great it flies.
As with every Old School Model Works kit, our Sport Air 40 is a build-it-yourself airframe, designed and laser-cut from high quality balsa wood and light ply.
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.
We have completely updated the airframe with laser-cut and self-aligning parts. The fuselage is built around a self-aligning, light-weight box for added strength. Surrounding this is the outer balsa skin, which is strong, light-weight, and twist-resistant even when performing high-stress maneuvers. The balsa/ply airframe makes the Sport Air 40 uncomplicated, lightweight, and easy-to-build.
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. Also the tray can be removed to give access for mounting an ESC or flight pack battery.
Another thing you'll notice is that the Sport Air 40 has a bit more ground clearance than a typical 40 sized design. It's longer landing gear give you the ability to easily fly from grass fields.
When it comes to aerobatics, the Sport Air 40 doesn't disappoint. While it may not be as precise as a dedicated pattern bird, it is incredibly forgiving and can easily perform a wide range of maneuvers. Even with the controls increased for aerobatics, landings are one of the Sport Air .40's strong suits, due to its excellent low-speed stability.
