Hi Jerry,

I looked for the paperwork, but wasn't able to find it. But basically, the flap
motor is controlled with a momentary switch. When you hold the switch in the
up or down position, the motor will run until you release the switch, or its actuator
rod reaches the limit of its travel. There are no external switches, or
airframe stops.

If my memory serves me correctly, the flap position is adjusted by changing the
length of the rod connects the two horizontal bars to the flap weldment arm,
and by the length of the wing flap push rods.

You could always call Van's & see if you can get a copy of the installation sheets
for the electric flap conversion.

Good luck!
