Man, it's a ***** getting that 75AX lined up so the crank is even with the center of the cowl hole, but that's probably because I don't know what I'm doing. I decided to ditch the 75 idea and put a .46ax on it instead.
Anyway, there might be a firewall problem with mine. I don't know if this is normal or not because this is only my third ARF and I haven't noticed this before..
I was installing the engine tonight and I realized the firewall, I guess you could call it the outermost firewall since there is a main firewall and then one that sticks out farther that the engine mounts to,.. anyways, the outermost firewall is 2 3/8" ahead of the main firewall on one side and 2 9/16" on the other. It really angles the engine. I tried washers between the engine mounts and the firewall, but then the engine is offset to one side once the cowl is on. I know some have built in thrust angles, but this just looks excessive...thoughts?
