I agree that that the LT 40 is a great trainer. This was actually my second plan and i built mine as a taildragger. My favorite main gear is this composite thing from Dubro.

I use it on all my planes which it will fit. Unfortunately it is only in one size. It is imposible to break yet has the right amount of spring in it. Aluminum landing gear always bends for me. If you use it as a tricycle on your LT, you may need to get an extra long nose gear to keep it level.[X(]
Make sure if you do a traildagger, that you move the landing gear forward to the leading edge of the wing.
