Greg,
With the adjustments that I made in the thrust, I too am running 0 degrees down thrust, and about 3-4 degrees of right thrust. I am going out to the field after work today (weather permitting) and we will fly it again. We think that with the change from left thrust in the engine to right, and the fact that we do have a 1/2 degree positive incidence in the wing that it should trim more like yours. As far as construction, I did add an additional firewall to the front using 3/16" light ply, and I moved the elevator and rudder servos to the rear of the tail. I also am using a pull pull configuration on the rudder. The battery and receiver are in the servo tray area where the rudder and elevator servos would have normally been. I did not move the tank to the cg, but could always go back to do so if the adjustments that I have already made need a little more. Will let you know how the flights go today.
