2 elevator servos
 

How do you setup the servos with the radio when using a separate servo for each elevator half? I've attached them with a 'Y" harness and plugged it into channel two of the receiver. My radio is a Futuba 6as (computer). When I move the stick, each elevator is acting like an aileron and moving in separate directions. I've checked the radio settings and everything I see is inhibited for elevons etc.

When using a Y for elevator servos you usually need a reversing Y... A reversing Y reverses one servo and has a potentiometer that controls where that servo's center point is.

The 6XAS may have the ailivator mix which allows you to use to elevator servos. You may also be able to create a simple mix that slaves the servo in another channel to channel 2...

When using a Y harness, you will have to run the arm positions of the servo opposite to the other. You will also probably have to turn one servo 180 degrees for the proper rotation. An easier way to do the set up is with Futabas' equivalant of JRs' Matchbox. Both servos plug into the Matchbox and only one wire from the Matchbox goes to the receiver. Both servos are set to the same position with this method.

If you are using a high end computer radio, the servos plug into separate channels in the receiver without a Y harness and the servos are "mixed" using the programable mixing available in the radio. The elevator becomes the "master" channel and the other servo becomes the "slave".

On the T6XA radios, there is no ailevator function, but you can slave the extra elevator servo in a unused channel to channel 2. The downside is that if you need to input elevator trim, only the master channel, (2), would see the trim and not the slave channel. That means that applying trim to the elevator would only trim one elevator half and not both. The T6XA mixing functions are more for taking out some unwanted rolling or yawing tendencies that happen during certain maneuvers like knife-edge flight. The mixes weren't really designed for ganging servos together like you need. A "mixing" Y-adapter like mentioned above would be a better option.

Geez, what a dope I am. Thanks guys, all I had to do was move the servo horn on one end opposite that of the other servoe :). I guess them being on each side of the plane, not seeing them togther made me do a Homer Simpson.. Duho.

Two elevator servos?

Sounds like you're moving up in the world Hoppy! :)

Yeah, Minnflyer, I purchased an older used CAP 232 from Midwest and am trying to get it ready before it gets too cold. It had standard servos and I'm replacing them with better ones. Man it's a big plane compared to my Four Star 60. Can't wait to try it out.
