Now that you mention that, I've definitely had 2 or 3 radio glitches now with mine! No servos failed yet but maybe cause I got too much paint on the bucket still
As always, I was shutting off the pump while hauling with the dump truck. Then when I flipped the pump on it was running but I had no hydraulics. I adjusted the dial for the 4th valve and couldn't hear it move. Figured the servo failed. It was 10:30pm, I just packed things up and called it a day.
2 days later I fire it up to see what's going on....all good!
A few days later, starting and stopping pump, suddenly nothing again. Turned radio and hoe off. Plugged back in, flip the switch..... All back to normal?
