RE: BEGINNER'S BUILD - Tower Trainer .40
I've actually seen some .40 LA's that were broken in well, using the right prop than run extremely well. Our club races Sky Raider Mach 2's with .40 LA's. I'm sure a few guys have liberally interpreted the rules but you'd be suprised how well these things run. You might be pleasantly supprised. I definitely wouldn't want a ST .45 in a light trainer. If I'd had that on my first plane, it probably would have been a pile of sticks before it ever got off the ground.
