Kudos for HiTec RCD
I recently sent in a 1 1/2 - 2 year old receiver that was glitching servos. (Warranty is 1 year )
Prior to sending it in I did the usual checks (different battery, disconnecting servos one by one, checking connections, etc.) I swaped the receiver out with a known good receiver and the problems stopped. I tried the bad receiver in another plane - same problem.
When I sent the receiver in I told them the unit was 1 1/2 - 2 years old, what was going on and what I had tried. I gave them my email and asked them to tell me how much and which forms of payment they accepted.
They retuned the receiver and replaced the antenna (I had lost a piece of insulation due to some sloppy CA. Taped over the area.)
Total cost: $0.00
That is what I call customer service !!!
