Greetings:

Looking for a better solution than routing the Trim Tab Servo wires thru the hole in the Elevator Spar (where the long Servo Motor Screw goes).

Does anybody have any pictures or diagrams of the Wire Routing of the Trim Tab Motor wires in the Elevator to the Horizontal STABILIZER to the fuselage.

Not much given on this subject on Matronics.

Thanks, Garey Santa Monica, CA

Hi Garey,

I just did this task. I simply drilled a 1/4" hole above the servo screw hole and added a little black plastic bushing. Attached is a picture.

Best regards,

I'm not that far along yet so I hope this doesn't sound dumb but what does
the wire go to, and what does it do?

Garey,
Drill a hole in the inboard elevator rib close to the elevator mounting weldment. Pass the wires inboard thru the rib. Attach the wiring to the round tube part of the weldment and then bring the wiring forward. Using this method, you impart a twisting type of bend along the length of the wires, rather than a pure bending.
Vans has also mentioned numerous times that additional holes in the spar will weaken it.
