OK.

If you're talking about 'EASY return to default settings', then that doesn't work, either. Unless there's some magic little button hidden somewhere, or some strange procedure that can be done without powering up, I'm out of luck. As I stated before, no matter what I do, BEC / no BEC, throttle up / back, throttle normal / reversed, I get beeping after five seconds. Straight error code.

I have since tried it with my Airtronics RD8000, and three other receivers with my MX-3, and I still have no luck.

Looks like I'm about to do some shipping (and waiting).

crud.
