The SIG KADET LT-40 EG is the latest ARF rendition of America’s favorite R/C trainer, now redesigned to accommodate either electric or glow power. Like all SIG KADETS, the LT-40 EG behaves perfectly in flight with true “hands off” stability. It’s large size and light wing loading lets it fly slower than other trainers. Slower speed gives the student pilot more time to think and react to what the model is doing.

Expertly covered with UltraCote®
(aka ORACOVER®) premium polyester covering material.The LT-40 EG ARF is engineered for quick assembly with a minimal number of parts.A photo-illustrated assembly manual takes you easily through each step.Quality hardware includes spinner, wheels, pushrods, fuel tank, etc.
Fly with Electric or Glow Power

For GLOW POWER use a
.40 – .46 cu. in. 2-Stroke or .40 – .54 cu. in. 4-Stroke Engine

For ELECTRIC POWER use a 500 – 800 watt Brushless Outrunner Motor, 50 – 75A ESC, & 3S-4S 4000-5000 mAh Lipo Battery Pack

Removable Hatch Allows Easy Access to the Fuel Tank (glow power) or Battery Pack (electric power)

Expertly Covered With UltraCote® Covering

Large tail surfaces & light weight construction provide stability and slow flight speeds.
  • The larger size makes the KADET LT-40 easier to see in flight.
  • The larger size gives the KADET LT-40 a lighter “wing loading”, which lets it fly slower than other trainers. Slower speed gives the student pilot more time to think and react to what the model is doing. That makes learning to fly R/C quicker and easier!
  • The larger size makes the KADET LT-40 more stable in flight. You’ll have true “hands off” stability on all axis. If the student pilot gets disoriented, merely let go of the control sticks and the KADET will recover itself and return to level flight.
  • The KADET LT-40 has a true “Clark-Y airfoil” for better penetration in the wind and more aerobatic capability than trainers with a totally “flat bottom airfoil”. After mastering straight and level flight, and learning to take off and land, you can learn loops and rolls with your KADET LT-40.

Dual aileron servos install quick and easy. Includes all pushrods and complete hardware.

Two-piece wing design is easy to transport. Strong aluminum tube Wing Joiner.

This is a all-wood ARF model airplane. All of the major components (wing, fuselage, tail surfaces, landing gear, etc.) are factory built and finished, and ready for final assembly. The motor and radio systems are not included.
Easy to Assemble and Repair
The LT-40 ARF is engineered for quick assembly with a minimal number of parts.
Because the LT-40 ARF is pre-covered in only one color (white), repairs are easy. All you need is white Ultracote® (aka ORACOVER®) and a new decal sheet. Even a major structural repair can be recovered to match perfectly.
Would you rather have a trim scheme that’s uniquely yours and doesn’t look like every other trainer at the flying field? Toss our decals and go wild. The all-white base is the perfect “canvas” for stars, sunbursts, and rainbows. Or, go with logos from your favorite sports team, drink, motorcycle, or company. You’re only limited by your imagination.
