Hello, I might be having a case of the "duhh syndrome". I cannot figure out how to set up aileron differential with my set up. I have a GP Spacewalker that has a servo for each aileron. I DO NOT have a computer transmitter. Is the computer TX the only way to set up aileron differential OR can it be done "mechanically"???
Thanks........ lownslo

Yes, it can be set up mechanically. All you have to do is place the pushrods in different holes, either on the servo end, or the control horn end. Personally I have never seen the need to use differential aileron throw.

If you set it up as described in the previous post one aileron will always move more than the other in both the up and down position. Is that what you want?

What you need to do is have the servo arm at different than a 90 degree angle to the pushrod. This way when the servo turns it will have more travel in one direction than the other. Actually the servo moves the same amount but because of the angle to the pushrod it creates a situation where there is more resulting movement one way than the other.

I don't think I explained this very well but it is a common situation in helis where all control rods should be at 90 degrees to the servo arm so as to eliminate differential.

Hi, thanks guys. Maverick, you did a good job of explaining. I thought that was the way to do it. I did that about a week ago and I had to "use my imagination" to see the difference!! Anyway, I am going to attack this thing again. Maybe I did something wrong the first time. thanks lownslo
