Sig Kadet LT-25

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.

Special notes about electric from Dave: This model makes an excellent electric conversion and is perhaps the most popular one of all time. Super light weight, large as or even larger than most 40 size trainers. The only lighter weight 40 size trainer on the market is the Radical RC Intern 66.
