RE: DSM2 receiver and DSMX transmitter
Do you have any amplified Y servo cables in your setup? Spektrum says not to do that and may have been passed on to the orange products. I have seen a servo on another channel cause a different servo to act up. Start with just the one servo plugged in, if its ok, plug another in and so on. If its still a problem, try a different channel. This should help hound dogging the problem. You may have just been given a bad receiver.
