I suspect the differences are barely notable in our scenario.
Hi Michael,
Yes, that's probably true, although, if the arms get particularly short in a small model to allow free movement of the arms in the fuselage, the slop / arm length might become critical.
What I do know is, I always put the pushrod as far out as possible to minimize the effects of slop, because, well, I might as well, if the arm length is there to be used!
