Is there any way to tell if it is a reverse rotation engine?? One more thing after we got it to start and run we tuned it used a tach to do this we got it up to max rpm then backed it down checked all the controls to make sure they went in the right direction and no mater what the plane would not leave the ground. It had enough elevator in it that if it did leave the ground it loop 3 feet of the ground seems like it just wouldn't pick up enough speed to lift he started out with a 10x6 and went to a 11x7 with still the same out come I just don't get it any ideas??
