Glitching, RX to blame?

[T3rry]

Hey All, i have been having a little glitching the last couple times i ran my truck, i'll give you a rundown of what's in it and then explain the issue.

The truck, is a xr10 switch, 35t Br00d creeps, dual mamba sidewinders sammiched, cc 10a bec, savox 1230 servo, 4pl with 2106GF RX

Ok so now for the issue, it's a pain because it's not consistent, once every 10-15 minutes, the truck will just drive on it's own, and it does this in various ways, the radio is non responsive during these episodes... Each time it lasts about 3 seconds
One time it was upright on flat ground, it just drove at about 10-20% throttle
another time it was upside down, only the front ran, same thing 10-20% throttle then back to normal
A couple times i had minor glitching on the servo, just a little wiggle 1/2 second, but throttle died out during that time
and one time the whole truck just went non responsive, but there was still power because the servo was whining.
i cant recall if i had dig on or anything

So, my troubleshooting has given me these observations:
One of the times i looked at the TX while it was happening and it had no action on channels 2 or 4, so i have ruled out the tx sending bad signals
The ESCs do not re-arm, so i don't believe it's a power connection issue
My RX is powered by the ESC, so it's not a BEC issue

So the only 2 left would be the servo, or the RX, and i just don't see how the servo could cause this... so, i think i have nailed it down, but won't have a chance to swap out the rx and test it til tomorrow, just wanted to bounce this off the pros out there to make sure i am headed in the right direction.



EDIT. i should also add, last night i ripped apart all my elects, make sure nothing was touching or grounding out, and stuck it all back together, and it made no effect.

A bad servo can muck up the system. I had a shift servo go, even with BEC, nothing worked right. It was glitchy and unresponsive. It "COULD" be a bad servo, or the servo is starting to fail. Do you have a spare servo to test?

i do not, but i do have an RX, so i think i will try that first (the part that sucks is i have my rx (and servo) soldered in, so it's gonna be a PITA either way, oh well, thanks for the response.

I had the same problem and I figured it was the esc but after spending a hour or so on the phone with axial, they figured out that my rx/tx was bad sent me a new one and boom all is good. So I'd change out the rx/tx

easier said than done, i am not prepared to throw a $300 tx in the trash I swapped out the RX last night and will be testing it today, in about 3-4 hours i'll be on the rocks to give it a test.

got out and played today for about 45 minutes and did not have any issues, lets hope i licked it, bad RX.

I was there and there was not a glitch to be seen.
