Thanks Twinman
I agree about not angeling the engines to compensate for a lost engine (lets face it you would have to have some serious angles to help in that situation). I like the idea of angling the one engine to help with torque roll as I will not be bothering with counter rotating props (more trouble than its worth) Is torque roll such a big issue on a twin ( with both engines on song of course). I guess the best bet would be to build in some room to adjust the engines on completion.
The aircraft of the building board is a 1/7 scale P-61 black widow in which I am using a pair of MVVS 1.44 ci opposing twin cylinder 2 strokes (low vibration) gotta love the sound of a pair of twin cylinders.
Thanks again Steve
