Signal splitter
Posted: Sun Mar 27, 2011 10:01 pm
Hi guys. I hope someone can help me out.
What I am trying to do is to hinge ailerons with no gap. I have done it on few of my foam planes and it works good... but with a small down draw - it has a free play in its neutral position.
It works like this:

To eliminate the free play I need to have a signal split between two servos that while one servo is moving the aileron down, the other servo remains in neutral. Then the first servo will remain in neutral while the second servo is moving the surface up. I hope it makes sense.
So far I tried using logic gates to create a 1.5ms pulse out of the incoming control signal and then direct the control signal to one servo or the other according to its width, while sending 1.5 ms (neutral) to the opposite servo. It doesn't work very well.
I know there are many ways to deal with this problem, so I am looking for a reliable, efficient, more less simple... well you know what I mean.
Any ideas?
