RE: dual elevator servos question
What I do to set up dual servo Elev.
(1) Tape both Elev. in nutral position and set linkage from servo to horn.
(2) plug both servo's in the apropiate channel.
This step is done best when rudder is not installed or pined to fin.
(3) Take two sharpen pencils and tape then both to the trailing edge of elevator.
(4) set the channel two servo as close to center as possible with the linkage or with the transmitter.
(5) set the Ch.8 channel (usually the left elev. servo) center so both points of the pencils meet
(6) then program the radio so both servo's work together with the elev. stick.
(7) then set the full travel up and down in the transmitter.
Whwn set where you want both center and end ponts are sapose to be, dont for get to write down all your settings on paper so you have then in case later you need to go back and reset the throws. You might even want to have a master copy in your TX of the factory setting. So you have it to reprogram to original settings.
Hope this is what your looking for.
You could always get a servo programer from hitec and set the nutral and end points on it, also Servo City sells a servo protractor that helps you set the center and end points in centimeters. Then the travels are manualy set prior to the servo install in the plane and if yo have to use a back up TX later on your settings are already set up in the servo.
