Guys, i have a new fibreglass fuselage of the Extra 300L which is designed for gas engines of 50 to 80 cc,s . the plan states no right thrust to be added when mounting the engine but when i measured the fuse it has left thrust built in plus the fin also has abit of left and not dead straight ahead. i thought normally right thrust is built in but not left , any help ? thanks.
The fuselage ? has left thrust? in the firewall?
The fin not being straight is a clue. Are there any model designers who used fin offset for any model?
