Any tips on down-thrust and Right-Thrust angles that have worked for other Magic owners with this engine combo ?
I tried the 12 1/4 x 3 3/4 APC prop everybody like so much and I didn't like it. It may work great on your four stroke. My old ragged out .46 couldn't spin it up quick enough for it to be the best prop. I went back to the 11x4APC
I mounted my engine a little differently, centering the muffler under the fuselage. In this setup it was easy to add a couple of degrees of right thrust and a little down thrust in the process. It is perfect.
