Wonderful quality Sig Kits here at Radical RC. These are KITS, not ARF's. At completion you geat a feeling of accomplishment and pride of wormanship that beginner RC'rs will just never understand. ;-)
The Sig Kadet LT-40 has become the R/C trainer of choice at many club fields. Not long after it's introduction, we started getting requests for a smaller version of the same airplane. So here it is - a compact version of the LT-40 - the new Sig Kadet LT-25. When price shopping this kit, be sure you understand our super low flat rate shipping means total cost to your door is probably the lowest on the planet.
"The R/C Trainer That's All Laser Cut", As you would expect, the new LT-25 inherits all the same gentle flying characteristics of the other legendary Sig Kadets. It has the same light wing loading, which allows it to fly slow enough to give the student pilot time to think and react. It has the same "hands off" stability on all axis. If the student pilot gets disorientated, simply let go of the sticks and the LT-25 will recover and return to level flight within seconds.

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.
Like all Sig Kadets, the LT-40 behaves perfectly in flight, with true "hands off" stability on all axis. If the student pilot gets disoriented, simply let go of the control sticks and the LT-40 will recover itself and return to level flight within seconds.
Because the Kadet LT-40 is bigger than the average .40 size trainer, it has a much lighter wing loading, which lets it fly slower! Slower speed gives the student pilot more time to think and react to what the model is doing, thus making it easier to learn to fly R/C. Every major part of this kit has been pre-shaped, sawn, die-cut, laser-cut, routed, or whatever it takes to make it ready-to-install right out of the box.
Setups below would be my first picks depending on your purpose for the model. If your trying to learn or train a beginner, or just want a mild model with enough power to get out of trouble, pick setup around 1000 to 1400 foot per minute climb rate (fpm). An expert can do quite nice aerobatics on 1000 fpm, 1400 fpm and above is enough for first season pilots. Setups 2000 fpm and higher is agressive power.

Actual performance may vary depending on components used, accuracy of data as provided by manufacturer, quality of battery, ESC, and many other factors.
First attempts at R/C flying should be with an inherently stable model that flies slow enough to give the student pilot time to think and react. The Kadet Senior is the result of designer Claude McCullough's 50+years in the model airplane hobby. Everything about the Kadet Senior has been designed to make it the easiest to fly trainer in the world.
The"Hands Off" Trainer; High-wing configuration, large tail surfaces, and generous dihedral for true "hands off" stability. The Kadet Senior flies so slow and gentle that just about anyone can handle it on their very first try! If the student pilot gets confused, simply let go of the control sticks and the Kadet Senior will recover itself and return back to level flight. Flat-bottom airfoil, light weight construction, and a super light wing loading allow the Kadet Senior to cruise around at low speeds.

When developing the Four-Star 40, SIG had two main design goals: First of course was impeccable flight performance, including the ability to perform any aerobatic whoop-dee-doo you can throw at it. Second, it had to be ultra-simple to build without looking like a "box with wing".

If you're looking for an R/C model that is easy to build and exciting to fly, the KOUGAR is for you! This sleek jet-style airplane has a fully symmetrical wing section for smooth pattern-like aerobatics. Ample wing area and a thick airfoil provide outstanding slow speed stability. Built-in wing "washout" eliminates tip stalling, enabling the Kougar Mark II to be slowed down to a walk for realistic nose-high landings. The Kougar Mark II is highly recommended as an introduction to low-wing flying and learning aerobatics.
Fully Aerobatic Smooth Control Response
Don't let the Kougar's racy lines worry you. Construction of this sport model is simple and straight forward. The load-carrying and equipment-carrying portion of the fuselage is basic balsa box structure. Once that is built, you add a molded plastic fuselage top, a molded clear plastic canopy, and a molded plastic cowling, to give the Kougar its modern jet-style shaped.
Are you having trouble shoe-horning a big model into a small car? Does the high cost of feeding a fuel guzzling .60 break the modeling budget? Well cheer up! Here's the answer to these and other big airplane problems. The little Kobra provides "hot dog" performance in a compact, easy to transport size. All of the great flying characteristics of our popular Kougar and King Kobra have been reduced into this junior-size bundle of excitement. The same sleek jet-style look, the same wall-to-wall aerobatic capabilities, the same built-in wing washout for slow speed stability, the same easy-to-build balsa fuselage with the unique formed plastic top - only in a smaller package! Plenty of room inside for standard size radios.
Kit features, built up wing, ABS cowl, simple box fuse structure enhanced with jet like canopy/turtle deck molding. Contains a generous hardware pack. Comes with full size plans. Fuse builds right on wood sheets, die cut formers and ribs. Alternate stab designs for both tail configurations.

Special notes about electric from Dave: This model makes an excellent electric conversion. My first large electric was one of these on 20 1750FAUP Cells. Yikes, I'd love to do another one with modern packs! Here is how I'd do it. Yes, this is same chart as the 4 Star 40, similar weight and wing area. An under recognized yet excellent electric conversion model. Good weight to wng area. A little troublesome to get large NiMH packs into due to the wing tube. However with Lipo's it's super easy to fit the pack. Below are my suggestions for a range of practical power systems.

The heart of this beautiful airplane is it's superior wing design! The light, strong, built-up balsa structure incorporates built-in wingtip washout for superior stability and control. Even expert pattern fliers are impressed with the Kavalier's smooth, responsive flying ability. Make perfectly coordinated, in-the-groove turns. Fly through any aerobatic maneuver with rock solid precision. Flare out for slow, main gear only landings with no tendency to stall or snap roll. Highly recommended as a student pilot's second model! Balse fuse, tail and wing with built in washout. Build it bolt on or rubber band mount wing with smei-symetrical airfoil. Steerable nose gear, prebent aluminum landing gear and rugged plastic cowling and canopy included as are glow engine mount, full size plans and photo illustrated instruction book.

Notes from Dave: This is absolutely my favorite glow sport ship of all time. It's a classic kit. There was just nothing more exciting on trainer night than to have a graduated student come up with one of these for his 2nd or 3rd aircraft and ask me to test fly it. I dare say, I'd put a whole tank through the model and say, yes, it's still my all time favorite! The model is very pattern like for it's size, super smooth and yet retains all the personality of weekend sport ship. Friendly yet aerobatic and even aggressive if you set the throws for more spirited performance. They land like a dream, are utterly trustworth in any situation. You'll love it as I do.

Although it looks like it's straight out of the 1930's, don't bother looking up this one in your aviation history books. The Spacewalker was designed by Jesse Anglin of Hendersonville, North Carolina and first flew in 1986! Despite the fact it is a relatively new design, the Spacewalker manages to capture all the spirit of Aviation's Golden Age.
This 1/3-scale model of Jesse's Spacewalker retains all of the charm of his beautiful homebuilt. Plans for the full-size aircraft were scaled down for the ultimate in scale accuracy. Construction is easy with pre-formed fiberglass parts and traditional balsa and plywood construction.

The Riser 100 is an excellent choice for the newcomer who wants to get started in soaring, or for the already experienced "glider guider" who wants a relaxing, easy-to-build "floater".
The Riser 100's modified Eppler 205 airfoil and 1000 sq. in. of wing area gives you the ability to fly in nearly any weather. The Riser 100 provides great "hang-time" in light lift conditions, yet has respectable penetration when the wind comes up. Rugged construction allows more time at the flying field and less time in the shop. Launch the Riser 100 with a standard high-start or winch, or toss it off the slope. Enjoy the challenge of silent flight!

The Wonder is best described as a very fast, go-where-you-point-it, turn-it-quick-or-it'll-be-gone kind of plane designed for hot-thumbed R/C pilots. With an .09 or a .10 size engine, the Wonder is actually a very nimble, aerobatic, smooth flying sport plane, but with a snarlin' .15 or .19 up front it's a hand- launched hot rod! Landings are no sweat thanks to the thick symmetrical airfoil and the light wing loading.

Special notes about electric from Dave: This model makes an excellent electric "muscle&q
uot; model. Often overlooked since SIG does not offer an e-version or any electric power system setup info. It's easily adapted. Below are my suggestions for a range of practical to extreeme power systems.

If a fast roll rate, sizzling vertical climb, and dazzling good looks turn you on, take a close look at the King Kobra's the largest version of the Kougar, Kobra series.
The foam core wing and unique fuselage construction get you in the air fast with a model that looks as good as it flies! For general sport flying, the King Kobra flys great with a sport .60 R/C engine and the standard fixed landing gear. However, for those who want to soup this model up to the max, the building instructions include tips on tuned pipes and retracts. A fully symmetrical wing and airfoiled stabilizer make the King Kobra fly super smooth. It can make an average Sunday flier look like an expert!

The Skyray 35 is an easy-to-build profile model suitable for a wide range of C/L flying fun. This excellent all purpose design is suitable for stunt, combat, sport racing, balloon bust, or general Sunday flying.
When equipped with a .19 engine, it makes a good first C/L trainer. Bolt on a Fox .35 Stunt engine, and the Skyray 35 will fly the complete AMA stunt pattern. Install a high-performance combat engine, and you'll have a real "Hot Rod" on your hands.
Died-in-the-wool C/L fliers will appreciate the Skyray 35's speedy assembly and super tough wing design - which features spruce spars and die-cut Lite-Ply wing ribs. This is one C/L profile stunter with a real difference!
Notes from Dave: I've flown electric control line a number of times and it's a real blast! Any kit can be converted with a little effort.
Suggested Fox 35 Emulator E-Motor Setup: Himax 3516-1130, Thunderbird 36 ESC, E-Flite Control Line Motor Timer, 3S 1500 Kypom Pack and 2 each 10-6 APC-E Props. Setup delivers 10,180 RPM (Fox 35 Stunt 10,200rpm), 58 mph pitch speed, 47 ounces thrust, 374 watts power @ 33.2 amps.
Suggested .19 Glow Emulator E-Motor Setup: Same as above except with 9-5 prop, 11,040 RPM, 52mph pitch speed, 34 ounces statics thrust, 246 watts power @ 21.9 amps.
Builder must refashion nose to mount e-motor and should be capable of doing this before placing order. We do not have special instruction sheet for this modification.
Here's a profile model that flies like a full-bodied competition stunter. The Twister makes an ideal stunt trainer for up and coming fliers, or an excellent practice airplane for the competition flier.
