Default RE: Phoenix Models F-20 tail linkages?


ORIGINAL: Quikturn

Thank you for the pictures Darthvaj! I had trouble uploading images too but I it's because my files were too big.

Looks like you set up the tail linkages a little different than Kmot did. Are there any bends in those linkages? I like you use of ball joint clevises. The control surfaces are not in line with the servo arms and make for a tricky setup. That may explain why some of these airplanes crashed.

As for the steering linkage, I plan on routing a pushrod from the rudder servo. I'll post pictures if this works out.
Quikturn, All push rods are streight from the servo to the control horn. I did have to notch out one bulkhead just aft of the servos to get the right angle. I thought about running a steering cable from the rudder to the nose wheel but i like the direct drive from a servo, i can adjust the endpoint and travel.
