The firewall is set at 2 down and 3 right, that seems excessive for a low wing plane. My Ultra sticks have zero right thrust in them. Does an electric powered plane have to have more down and right thrust than an glow plane? I'm not comfortable starting out with that much angle for my glow conversion. I'm mounting an OS 40LA in it by the way. Its an old engine that I had laying around and wanted to use. It ran great with a 10x6 APC, but it was pulling a larger plane around. I might a 12x4 or 5 with the smaller plane.
