Seagull 540 elevator servo arrangement
 

Am I missing something here? The manual shows the two servos at the rear of the plane - no problem there....but the pushrod arrangement is not symmetrical.

I was always taught both servos should be mirror images of each other, meaning if the pushrod on one servo is closest to the horizontal stab, so should the other one...

Comments?

You need a servo reverser or a matchbox to do that, else your elevator will act like an aileron.

non-symmetrical servos
 

The Pacific Aero Model Gee Bee Model Y had the same suggested arrangement. It saves the builder from either electrically reversing a servo or from using an in-line servo reverser. As long as the geometry of the servo-to-horn connection is the same on both sides, it'll work just fine.

(If it were me though, just for asthetics alone, I'd reverse one servo!)

what remote do you use

I'll be using a JR 8103, so I'll just reverse one of the elevator channels. Too bad they show it the way they do in the manual. If you don't have a computerized radio....you will need a servo reverser like Dick said.

Covering was excellent but what blew me away was the painted pilot + installed canopy! They 'hit' on two of my shortcomings:-)

I felt the same as you do so what I did was moved the one that was supposed to be under the stab to a location that was directly across from the other that way both throws where the same. I put some photo's of this on the seagull 540 pictures post under the arf section.
