Need some guidance here. Bought a MM off of ebay from a local guy. He sold it practically ready to fly with exception of a radio system. He advertised it with an OS 61, but when I got home I was pleased to find an OS 91 under the cowling. Anyone flown this plane with this setup? Also another thing that bugs me....and maybe someone can give me a clue, but the engine isn't inline with the rest of the aircraft. The firewall is angled to the starboard side of the aircraft. I've heard of angling and engine down and to the right one degree, but this angle is highly noticeable...and I'm starting to notice this trend....I bought this MM because I want to hit the Tarmac and put off building my p-51 with a saito fa-100 because the firewall was angled the same way.....thought maybe I just bought a crappy ARF and I would have to shimmy the motor mount to adjust for the angle. Can anyone clue me into this? Is it a torque thing? I just can't see how an aircraft can fly true with the engine at such an angle.

Any comments would be appreciated!
