Help!
servos, ailerons

Thanks in advance for any help, I'm trying to set up my plane (home made p-38) I would like to have a servo for each one of my ailerons. My set up is two ailerons, and elevator. My rx is a Spectrum d6xi, and my receiver is a Spectrum AR 400. I tried using a y connector but of course the servos work together both going in the same direction, I would like to control each aileron separately.

There's a simple trick for that. You place one servo so that the top of it, with the servo arm, is pointed towards the right. The other one is placed so that the top is pointed to the left. When a signal goes out to those servos, one extends, the other retracts.

Thanks Joe, I will try your trick it should be an easy fix, although I was wondering if there was a way to control both servos through my d6xi, that way I could trim them separately.

You can lay the servos horizontally or vertically. As long as the axles of the servos or the arms are pointing in opposite dierections they will work the ailerons OK.

I don't know about dx6, but most transmitters you'd plug the second aileron into channel 5 or 6 and there will be a mix function that joins the two, except one channel is reversed. It's probably the most common mix so I'd be surprised if yours doesn't have that capability.

It is possible to control the aileron servos separately with a DX6i (using DualAile mode in wing type).

But that uses channel 6 for the second aileron....so you can't do it with a 4-channel receiver like the AR400. It doesn't have a channel 6 .

Just use a y harnes and have both the servo horns either facing one another or away from each other, try and get the horns as centred as possible and adjust pushrods to suit, making sure the ailerons are dead centre when you make/adjust your pushrods. That is the easiest way.
