Davey_flyer,

First I would check the plane while it is on the ground. That will probably help some. Also your engine is new. When I was breaking in my 91FX it shoke quite a bit on my Ultra stick 60. It still shoke after break in but not as bad. A big thing that causes shaking is prop balancing. Be sure that your prop is perfect. I was breaking in my BME 44 with a 20 X 8 which I thought was balanced perfect. Well I was getting a lot of shaking. I went back and rebalanced the prop. It helped a lot.
