Thanks for explaining it for me Ken. I didnt think to do so when I made the comment. [8D]

I have seen it happen more with FM receivers than PCM receivers and also I have seen it a lot more when turning OFF than turning on. Some setups I have seen do it several times and some turn on/off the wrong way all the time and it never happens. That I cannot explain, but none the less it is a fact.

If you ever see it happen you will understand why you need to supply the signal before you turn on the receiver and vice versa. The servos can go to maximum throws and lockup and can cause significant damage to the servos.
