Hmm...well now I'm REALLY at a loss to understand what went wrong. I just did a test of the radio components using the same battery I was using on my ill-fated flight and everything works perfectly.

Was I shot down? What does being shot down look like? It sure didn't look like anyone else was controling the servos. As far as I know the only other user of my channel was the one who held my model as I was starting it. Our club operates a "take the channel tag" system of flight control and I had the tag.

In RealFlight I sometimes see the failure message: "Your radio was intermittantly locked out." What does "locked out" mean here?
