I've been fooling around with my motor drive settings (Dead Band,IR Comp. Response) Another thing happening is my swing won't stay centered from time to time and if I re bind the DX7 again that fixes it for a while. I've never tried putting capacitors on the motors like the lower voltage ones everybody uses because I'm running 90VDC motors and I don't know what uF capacitor to use. A week ago I bought a used line conditioner voltage regulator and we'll see if that takes care of possible voltage drops.

I know nothing about 90V motors but the capacitors work well on the 6&12V motors. But if you have glitching there is probably some kind of electrical noise somewhere. I have heard that the 2.4 radios are better about this. I am using the 2.4 on my truck and it works great even without an antennae but the shovel is on the old 27mghz band. If this problem continues I will be changing radios.
