Hello Jonathan, Frank Xuereb here. If you watch 'a plane is born' when he gets
the engine delivered Mark gives quite a good explanation as to the reason for
the offset. Basically on full throttle the wind wash created by the prop would
hit the port side of the fin and give a tendency to push you to the left. This
is of course easily corrected by right rudder input but to help reduce this
effect the back of the engine is offset by 27mm but keeps the prop flange at 90
degrees.
Good luck, Frank kit 165
