I have a slash 4x4 and when i give it throttle it stutters then esc flashes red. It is a 2pole traxxas brushless system. I have tried 2 different batteries same result. I have replaced the esc and motor and it is doing the same things. I am thinking it is a reciever but before going and spending the money does anyone have any ideas?

ED Codes and Protection Modes Solid Green: VXL-3s power on light. Low-Voltage Detection is
ACTIVATED (LiPo setting).
Solid Red: VXL-3s power on light. Low-Voltage Detection is
DISABLED (NiCad/NiMH setting).
Very Fast Blinking Red: Thermal Shutdown Protection and Low
Voltage Protection have occurred at the same time.
Fast Blinking Red: Thermal Shutdown Protection, Stage 1. If the
motor has lower than normal power and the VXL-3s is hot, the VXL-
3s has entered Thermal Shutdown Protection, Stage 1, to guard
against overheating caused by excessive current flow. If the motor
has no power and the VXL-3s is very hot, the VXL-3s has entered
Thermal Shutdown Protection, Stage 2, and has automatically shut
down. Let the VXL-3s cool. Make sure your model is properly geared
for the conditions.
Slow Blinking Red (with Low-Voltage Detection on): The VXL-3s
has entered Low-Voltage Protection. When the battery voltage
begins to reach the minimum recommended discharge voltage
threshold for LiPo battery packs, the VXL-3s will limit the power
output to 50% throttle. When the battery voltage attempts to fall
below the minimum threshold, the VXL-3s will shut down all motor
output. The LED on the speed control will slowly blink red, indicating
a low voltage shutdown. The VXL-3s will stay in this mode until a
fully charged battery is connected.
Alternating, Blinks Red then Green: If the motor has no power,
the VXL-3s has entered Over Voltage Protection. If a battery with
too high voltage is used, the VXL-3s will go into a failsafe mode.
WARNING: If input voltage exceeds approximately 20-volts, the ESC
may be damaged. Do not exceed 12.6 maximum peak input voltage.
Blinking Green: The VXL-3s is indicating the transmitter Throttle
Trim is incorrectly set. Adjust the Throttle Trim to the middle 0
setting.

Have you verified your batteries are fully charged?

They are charged and work in other cars i own. The hobby shop said it was a short in the wires to the motor before i replaced them. But the same problem with new ones.

seems I remember posts of servos causing issues with the esc on some cars, have you tried a different servo?

Very simply, unplug the servo connection from the receiver. Once you've done that, just set it down in your driveway or the parking lot (if you're in apt complex) and just try to drive it forward and back. If it moves, your servo is shorted, and is causing a problem, and needs to be trash-canned.

What batteries are you using? Any chance ESC got flipped. Instead of being in lipo mode, was in Nimh mode. Or Nimh mode tying to use lipo.

Don't throw the whole car out, this can be solved. That's the whole reason we have hobby grade cars instead of toy grade. So we can work on them. Have you looked into which mode from the 2nd post the flashing most closely resembles? Start there to at least know what the blinks even mean.
