My LT is laid up waiting for some post off runway acrobatics. Just after getting airborne - dead stick. We have plenty of prairie dog holes and the LT found one.
I mis-typed - thinking ailerons I typed elevator. It has plenty of rudder and elevator but rolls - well you start today and end tomorrow. After the snow melts ....
Ahh yes, my brother-in-law had a GMS .47 on his LT-40 and we could not keep that one running for anything. We got lots of deadstick practice with that airplane. But we were actually flying off a private strip for full size airplanes so we had 2500 feet of smooth grass to play on
You know, moving the CG back might help a wee bit with the roll rate as well, plus, yo could increase the aileron throws a bit. Another trick that I like to use the mostthough, when you are doing your roll, use a bit of rudder to help it around. NOTE: this will only work if you have stock dihedral. If you have flattened the wing at all, the rudder will not help it roll. By the way, a stock LT-40 CAN be made to roll using ONLY the rudder
But all that being said, the LT-40 is a trainer, it is not meant to be super aerobatic. Look at it this way, when you go to get your pilots license for full size airplanes, you do not start in a Pitts Special or Extra 300. You start in something like a Cessna 150 or 172. Why not give your R/C beginner the same treatment, start with docile, slow, and easy to fly.
