Here is the flap circut from Chuck Dunlaps RV6. I added up and down limit

switches, but it is the simplest circut I've found. The diodes across the
relay coils absorb the inductive spike and extend the life of the switches.

Thanks again Chuck,

The limit switches won't work with this circuit. Once they open, the motor
cannot be actuated again unless the limit switches are shorted. My circuit
works with Van's motor because it free runs at the end of its travel without
hurting anything, so it doesn't need limit switches. If you have a mechanism
that would bind at end-of-travel, you will need limit switches and a
different (more complex) circuit.
