Ok here is the situation. I'm running a saito 1.80 on my cermark pitts. On takeoff the aircraft wants to torque left severly. I have put in about six degree's of thrust but it still has an issue and I'm just about out of cowl clearance! When in the air the aircraft crabs alot and the rudder needs a ton of right for straight and level flight. Also this aircraft has an issue with nosing over on taxi and I personally cannot obtain a better C.G. than what it has now which is dead center as far as that topic is concerned. I am taking off from grass. Anyone who has any info on these topics would be greatly appreciated this plane is a handfull on every flight and since have put it away untill a good fix is retrieved. (lots of money) Thank you all who reply!!!!!
