Have you encountered this?
I have to assume you are talking about when someone turns on and you are on the same freq?
I use PCM, it is less affected by getting hit, and if you do, it goes to a pre-programmed position. I like that better, but the PCM part is way nicer. I have been in the air a couple times when someone turns on their trans on the same freq. It didn't affect me. Their plane went nuts on the ground, luckily it wasn't the other way. They would have gone down.
