My friend JUST sent me a short snippet of the video he took of the RC4WD 4200 excavator he took. This shows the track freewheel problem I'm talking about. When I try to dig, the tracks freewheel, & pull the machine towards the bucket. They SHOULDN'T move, as they are doing. RC4WD is sending replacement parts for it. I'm sure they will get here before the upgrade kit from SoylandIndustries does. I'll R+R the stock motors, so I can use the machine, until the upgrade kit gets here. Once the upgrade kit arrives, I'll switch to those motors.
