Shogun, Forget "many", there arn't "any" with right thrust built in. Its not in the design and "right thrust angle is not required" according to the techs at GP. They have built an offset into the vertical stab to compensate for the left pull caused by thrust. It totals 1/16" in the 4.5" length of the stab. Earlier on in this thread someone graciously figured out the exact angle from my dimensions but I forget the degree and who knows where its buried in this thread. Standing at the tail looking forward on the right from the fuse side in to the vert. stab. its 11/32" and on the left side its 9/32". Perhaps their research was with a less powerfull engine than the Saito 100. If thats the case than it could use more angle. Also I measured a couple tail sections and the measurements are not consistant. As far as the angle of the engine some of us have elongated the mount holes on the mount with a dremell and moved the mount over further to the side trying to keep the spinner in the center. You are correct, spend some time setting it up or forget hovering. Joe
