Most LT-40's are tail heavy when built to plans. Mine balanced out okay, but that was because I used a .46 Magnum, which is heaver than the OS many people use. I've had good luck with this engine and for a trainer it might not be a bad choice.
I have built 3 kits and 1 arf and none of mine was tail heavy and
several guys at the club has the LT-40 and there not tail heavy.
I put the enya 40 and the os52fs on the planes i built.
The guys at the club has different types of engines on
there LT-40 and have had no problems at all.
