Guys this is the controller board I used for my wing sweep.

The original yellow board did a meltdown on me on the bench.
This contraption allows you to take a regular servo input (Pulse Width Modulation) from the Rx and control your wing sweep like a giant servo.
You need a feedback Potentiometer to keep track of the wing position. I used the same 5K Pot that was in the original wing sweep mechanism.
You can configure this board with a PC to program speed, endpoints, overloads and a number of other functions.
Hope it helps,
Steve
