RE: Dual Elevator Servos
If you already knew the answer, then why did you ask the question?
Because I had a heck of a time getting my plane set up right.I tried the reversing y and then tried a dual elevator setup with my Futaba 7C.With the reversing y I could not get it right. With the 7C I had problems with equal travel between hi and low rates.I finally discarded that idea and ordered the reversed servo.I am using JR 126 MG servos on my Goldberg Obsession's elevators and ailerons.I was glad to see I wasn't the only one with issues setting this up.Also,I asked the question because I was wondering if,when JR reversed the servo,that wouldn't put the travel differential the same on both sides.

RE: Dual Elevator Servos
I totally agree myself! I have tried cheap servo reverser's and spendy ones, they do not work perfectly. I finally went to a 9 channel radio because I was tired of not having it perfect. With mixing in and mechanical linkages set as perfect as I can, I have it nailed down. If run dualies I will definately get a matchbox or equal.

Do most on 29% and larger planes use an servo reverser or program a slave channel when using dual elevator servos

I am pretty picky with how the throws match up too, I use a pair of 24" long carbon rods taped to the elevator halves to match travel and they have to move in perfect sync at the tips all the way through the range of motion for me to be happy.

RE: Dual Elevator Servos
On my 9C I run a mix on the slaved elevator channel, mixing it to itself. I set the mix switch to be the same as the rate switch, and have it set for "on" when in low rate. This way I can fine tune the second elevator to match the primary when using lower rates. Works well, last long time, no five dolla.
