ESC/Servo issue *help*
I have an RC10B4 RTR, (I know this is the on road forum, but it's an electronics issue so I am posting here for more feedback)...it came stock with a LRP runner plus digital ESC and an Airtronics 27mhz AM radio. I was running a standard servo in the car, it worked but was slow and not really up to the abuse of racing, so I replaced it with a used JR DZ8550 (hi-speed hi torque digital).
The servo works fine, but when it moves the light on the ESC goes from a dull glow to bright. The change in color indicates that the ESC is switching form neutral to some other function. Again this happens when you turn the wheel on the Transmitter, with no input to the throttle.
When you have the throttle on and the motor is turning, movement of the steering servo causes the motor to hesitate, and it looks like the brushes are arcing. The ESC led shifts from dull to bright every time you change direction of the steering.
So somehow it seems the new servo is interfering with the ESC. Switching back to the old servo (which is not digital) cures the ESC problem. I have gone thru the set-up again on the ESC, the esc and receiver are seperated, no bare wires, etc.
Are digital servos known to cause problems on an AM radio? Could this be a problem with the servo itself? Or the ESC? I plan on upgrading the radio to a computerized FM (A JR XS-3) but that will probably have to wait a bit for my budget to catch up some. I would appreciate any thoughts or experience that you all may have.
