Hi,
i'm about to replace the Rotax 582 by a Nissan MA12 engine in my KFIII.
The engine mount is made by myselfe.

I heard that sometimes aircraft engines not mounted exactly 90 deg. to the lateral axis and even not to the vertical axis.

This is because of a "side pull" of the propeller.

Does anybody has some information how this relates to a KFIII
Thanks for your help.
Frank
