I am not sure of the correct terms… but…. I know the best geometry possible is to have the pull pull cables centered with the center of the hinge line. On the “per plan” E1 the elevator “bell cranks” are elevated above that center line. The design of this is ok since it allows all of the servos (elevator and rudder) to be mounted on the same tray, but I don’t think it’s the best geometry possible. My ideal system would be to do away with the “bell cranks” and side mount the elevator servos so that the center of the servo horn is lined up with the center of the elevator hinge line. But I think the wing tubes will get in the way on this model. So the next best thing in my mind is to lower the bell cranks and servos to put them in-line with the elevators. Then raise the rudder servo (a box off the servo tray) to line up the rudder servo. Still need to kick the ideas around a bit.

I like to tinker (design) and fabricate so this modification won’t be too difficult. But it is certainly not necessary. This is the reason I like kits over ARFs.

I’m not sure if that would make more or less room for a scale cockpit, but that’s not my intention with this build.
