Hello everyone, I'm new to this forum and I have a issue that I can't believe I can't figure out. I bought my son a hobby wing ez run 25A-sl brushless esc and motor program card and I installed it into his car but the esc will not calibrate with the controller. I have put epa 100 both forward and reverse, I've put trim at zero. Turned abs off and tried it both normal and reverse directions. I don't know what else I can try to calibrate the esc and controller, the controller is a fs-gt3b. If anyone has a suggestion I would greatly appreciate it. Thanks

Are you getting any response at all from the tx?
