I am rebuilding a Graupner C17e. It had a 380 as power, I am replacing it with a Mega 16/15/4 motor. The existing motor mount is a
red plastic can shape that is angled so that when the craft is on the ground the prop shaft is parallel to the ground. This is a tail dragger, at rest the nose is 3.5 inches higher than the tail. I have never flown the plane and assuming that in flight the fuselage would be level giving the motor shaft a downward angle of about 18 degrees. Does this sound right? My P-39 is not a tail dragger and on the ground or in the air the motorshaft is the same. Also I am converting to Floats, so the fuselage will not be
at as much an tail dragger angle. Is there any 'rule of thumb' for motor angles?
Thanks
