Its a Sig Mayhem (a taildragger) with a Saito 56 on it. The specs call out 2 deg rt thrust and its at 0. The cowl was my first clue before I measured it. You can see in the picture its designed for it in the cowl. I dont think its in the firewall in this kit you can usually see it. The motor is square with the mount and with a 12 inch prop sitting level its the exact same measurement from the vertical stab to both blade tips. 2 degrees should give about .21 inches difference.

I notice it most on full throttle vertical flight, initial climb, and take off roll, in that order.
