Yes, I have have tried three different GWS 6 channel receivers, and even changed the crystal. I rerouted the antenae several times. I've moved the servo extensions, the esc location, the routing of the motor leads,and the location of the receiver itself. It's really wierd because all of the receivers are working perfectly in my Tribute, Tensor, and Mini Funtana. Looks like I'm in for a new Futaba or Hitec unless somebody has an idea.
