      We have an AA1B and are looking for a replacement flap motor or an overhaul faculty for the motor. Please let me know if any one has any ideas on where to start looking.

      These are getting very rare. I assume you have already checked with the usual suspects (Fletchair, Yankee Aviation).
      I have a couple of dead ones. I have not yet heard of a shop that can rebuild them. I tried taking one apart, but it is not a simple task.
      On the other hand, the brushes are easy to change. Have you tried that yet?
      There was a factory service kit to install a late model AA-5X flap motor, but that required lots of changes to fit it in there. The factory did this as they were running out of spares of the AA-1 flap motor.
      Here is info on the Service Kit..

      Thanks for the information.

      Where would I find the brush parts to change those?

      First pull them out and inspect them, then check with the Usual Suspects.
