i have a pair of castle 240hv hydras that have a handful of runs on them in my hpr 135 with castle 2028s. they have all been cold, on 8 or 9s with no issues until run 4 when it went wide open throttle out of no where and crashed into shore.

2 months later i decided to pull it off the shelf and see what failed. my thought was a bec or rx failure. well when i plugged everything in the same as always, my esc will beep, arm, and then do nothing with throttle input. recalibrated escs again, and same problem. the led blinks red after i try to input throttle. tx end points are at max. they will beep to calibrate, all beeps to program. but nothing at throttle input.
