I just flew my extra 330 this past weekend and while setting up for a torque roll the plane wants to fall out to the left before it starts to rotate almost every time. I will admit that I'm learning how to TR but I'm always good for at least two full revolutions before I fall out. It seems that maybe I dont have enough right thrust. I built the plane to specs but used a BME 44 for power. The manual says it has 1 and a half degrees of right thrust built in the firewall. Is this enough? I did'nt have this problem with my edge or my buddies 33% extra while torque rolling. One other note, when the plane starts to fall out I will feed it full right rudder but it still wont correct unless I throw some elevator in it. I do have at least four inches of throw in the rudder. I'm not sure why the addition of elevator helps. Once again, I have only had this problem on this plane. Please help.
Thanks,
Bruce

turbobruce,
I am in the process of building a DP Edge with DA50, and I'm wondering if the stock, built in thrust will be enough. You said your Edge was fine, but the Extra isn't.
Does the Edge also have 1.5 degrees built in? I don't recall the instructions stating. Thanks.

If you go with more power then you may need more right thrust. Bigger engines have more P-factor, Torque, and Spiraling Slipstream, requiring mroe right thrust to offset. My DP Extra was good with a Moki 1.8. I set up my thrust line by pulling vertical and seeing if the plane wants to pull one direction or the other, and setting the thrust angle to counter that.
