I picked up this auto pilot while it was on sale for $19.95. It's back to original price now.

Spent a couple of weeks installing it on my born-again HobbyKing EPP FPV test platform and bench testing it. Worked great on the bench.

Here's a short video of it's maiden flight from a couple of days ago. Obviously more testing required and now I know why most models are painted white!

Too bad Frank. 
What was impressive however, was the flight data record, which led you to the crash site?  Great!

The log data was stored on board the plane...
