Re: RC4WD Excavator
Joe, I applaud you for taking a chance on this purchase! You have so much experience with hydraulic construction equipment that I believe you made an educated guess from the photos and info that the gamble wasn't too big.
It seems to run quite well. The very high pitched sound to the motor/pump concerns me the most. It could either be a bad bearing or the magnets in the brushless motor are touching the armature.
