Castle Mamba X 8s acting up, no throttle

[Moirae]

Yeah that's the same problem I'm having. Except mine go through the chimes at start up but right before it arms it gives one really long beep and then nothing. No throttle. Was working fine... now nothing... I feel your pain. I have re-bound and recalibrate and charged everything. Going to reset everything to factory and see if that helps. I really like my castle motor but if this keeps happening it isn't worth the headache...
