I have a truggy bought only 3 months ago with a HobbyWing WP MAX10 SCT RTR 120A. Lightly used, not in dirt or water without any problems for the first 3 months.
An issue occurred the other day. I took it out and drove it for 1 minute about 200 meters then the following issue occurred:
Every time the throttle is pressed the car accelerates for 1-2 seconds then auto-brakes with 3 green flashes with 3 beeps and then afterwards flashes red continuously while the throttle is still pressed (no beeping). When the throttle is placed in reverse, the motor doesn't engage, only the 3 green flashes with 3 beeps and then red continuous flashing (no beeping). It seems that there is some protection kicking-in - green flashes are typically overheating - but the car has not been used and is cool everytime I have tried to troubleshoot.
Link to a video of this issue:
This issue occurs with or without a motor. I have done the following to troubleshoot:
-Have used different 3s lipo batteries.
-Tried multiple Rx and Tx's and it is not a receiver or transmitter issue.
-Have recalibrated the throttle each time the Rx/Tx were replaced.
-Made sure that the throttle was dial was on 100% during recalibration (tried in both normal and reverse modes)
-Have reset all the ESC programming to default.
-Have verified all the ESC settings and tried different options.
-Have unplugged all unnecessary cables from the Rx.
-Have reseated all the motor and ESC cables to make sure they connect.
-Have tried another motor and same issue occurs.
-The transmitters have fresh batteries.
-Haven't run the car through water.
-No dirt lodged in the ESC fan or heatsink.
-The ESC is not overheating as this happens when the car is cool.
-The fan on the ESC runs fine. Final point.
-The steering works fine.
Based on all the testing and permutations, this is definitely a problem with the ESC and since it is not so old I guess this is some kind of configuration corruption in the firmware. Hobbywing won't entertain this issue as it is not directly from them and without their specific branding. I know there must be a solution for this as it is almost working....
