I've got two receivers right now that should be sent in and checked. Problem is, I can buy a hitec 8-channel all day for 39 dollars. I don't have those high-priced receivers so I'm probably under the radar of most of the repair guys. One is an electron 6 and the other is a Futaba FP-R129DP. I've got some other servos to send in so I might send them all at the same time.
