HELP! I recently had a catastrophic crash on my maiden flight of a Hanger 9 ARF: P-51 Blue Nose Mustang. On takeoff the plane rolled to the right I believe since the right landing gear was severely damaged. Also, the fuselage ame aprt in two pieces as teh nose hit the ground. I am assuming this was due to an uncompensated engine torque problem. I seem to remember a formula of 0 .1 ounces of counterbalance for every 0.1 cu. inch engine displacement. the engine is a TT F130, 4 stroke. That means I should add 1.3 ounces to the left wing? Any thoughts on this?
