Hahahahaa ... HUber its not an OSPREY! Its 45 degrees radially. Anyways, the plane was built true and I think its the engine thrust. I added in a washer to get some down and left thrust. Thanks for the feedback guys ... anyways here are some pics of the plane.
Firstly, what are your trim settings when you are flying at full throttle? This will tell you what you are fighting against. So, you need to adjust the thrustline to produce the same forces, but in reverse, at the front of the plane.
It is clear from the pictures that you have way too much left and up (as far as the thrustline goes). Center the thrustline with the center line of the fuselage and then add 3 degrees DOWN. Fly it and see how it behaves.
I think you will still find the model rolling to the right a bit. That is due to the prop wash on that huge flat fuselage. You can then add 3 degrees LEFT thrust and see what happens.
