Fuselage Final Install: Elevator Control System

The elevator control system is complete. The setup runs from the control sticks all the way to the tail of the plane where the elevator attaches. Reminds me of driveline for a vehicle transmission. Next couple pics show the entire length, first one shows view looking forward from battery compartment.


Here is view looking aft from battery compartment.

This is a universal type joint right behind the torque tube. The purpose of this connection is to allow the torque tube to rotate independently of the push-pull tubes. The joint also enables the series of push pull tubes to function with a change in vertical alignment.

Here is another transition connection where the push pull tubes are attached and can move back and forth at a vertical alignment change.

Here is the end of the system where the elevator will ultimately attach.

With some 3-in-1 oil applied to all of the bushings and adjustments of nuts here and there, I've got most of the friction out and control sticks feel pretty good left, right (torque tube-ailerons), front, and back (push-pull tube transmission-elevator).
