Seriously, sounds like a radio problem. Quickest way to determine that is to hook up your RS Pro to your buddy's radio (that is known to work) and test it out.

Conversely, you can hook up a known good speed control with your radio and if that behaves, it's the RS Pro...

Did you recalibrate your RS Pro to your throttle? I think all ESCs has some button or routine to get the end-points of throttle/brake and neutral point of a radio.

I'm sure you know, but CH1 on the receiver is for the steering servo, CH2 is for the speed control.

Do you have another servo you can try? Does it only happen when you turn fully to the one direction or even if you only turn the wheel a little that direction?

Have you adjusted you epa so that you just get enough servo movement to get you full steering and not over stress the servo by it trying to turn farther than necessary?

if i adjust the travel (which i assume is the same as epa) to 60% the problem seems to go away... I was just trying that as you suggested it... Does 60% seem low? I need to confirm that the wheels are at full lock at around 60% to see if that is the limit... It might be??? It is a 4wd buggy if that makes a diff... on my stadium truck the travel is set to 100% with no problems...

As a point of interest... at about 65% the problem is intermittent and the wheel on the side of the issue seems to rotate a bit on the rough side...

I would also check the motor, I know when I was running a 278 in my 4wd in would do weird stuff on the straight, especially later in a race when the battery had fallen off a bit but I later found out it was taking all the power for the motor and not giving me enough for my steering servo which would cause the car to veer on the straights at full throttle....something to check out.
