CG problems
my second plane build is the tower trainer 40. my first (from scratch) was a SIG KADET SENIOR.i had no problem with its center of gravity. now it looks like the TOWER TRAINER 40 needs about 2 ozs at the tail or about 6 ozs right behind the servos to get it balanced. is this right??the tower 40 was a ARF. could this be the problem? please help. if you have any more questions please ask. THANKS
