Dave, the other thing you can do is to beef up the bec or put in a Rx battery. Slowing down a servo with the radio draws a little more power... and we're running 4 at the same time here! Not to mention, you are still running flight servos and since the flaps are going slow, there's a greater chance the gear is possibly being cycled at the same time. There ya go, you just put it all to the test. Big draw on the bec and the entire radio system. So, what has the biggest load? Hint, a big surface that is really being pushed on. The weakest link will shut down first. If it was your right outboard flap as you say, it will seem as if it's not working. Just like a servo that has no power to it, you can move it with a bit of pressure.
Most of the time we don't see a problem. But, planes are all different with different loads, some linkages, some hinging, whatever. Becs are generally put right at the limit with these bigger planes. That's why it happens randomly sometimes.
