I have a TLR 22 with a DX3R Pro, SR3100, Spektrum servo, Tekin RS esc and Redline 13.5 motor. When the car is at a stop, the car will barely go it is glitching so bad, but once it gets going, it's fine. I have tried changing motors, esc's, receivers, and batteries. I've re-calibrated the speedo and radio. I've tried two new sensor wires. What am I missing?

Do you have any of your wires braided together or coiled up (looks like a pig tail, curl Q)? This may be causing some electromagnetic interference or radio frequency interference. What battery are you running?

Yeah, I've got my servo wire all bunched up. The thing is though, it worked with this exact setup perfectly for about 10 hours. I'm running a thunder power 25c sport pack. I was thinking maybe the radio and speedo didn't like each others settings?

A quick easy way to see if it is the servo wire causing any EFI/RFI would be to simply unplug it and then see if the esc works correctly.

I just tried updating the ESC and unplugging the servo, neither made a difference. The only other thing I can think of is the radio itself. It's pretty new(about 12 hours on it) so any defect may just be showing itself. Hmmmm

are you running a sensored motor? If so, try a new sensor wire, a bad wire can cause the car to glitch and cog at low rpm's
