I recently purchased a 1/18 18.5t sensored motor and Xcelorin ESC for my mini rock crawler pro.
It worked flawlessly for a few days.
I first noticed this the other day. At the top of an incline the crawler buzzed and stopped moving. I thought it was the slipper but found it odd because the truck was not in any kind of bind.
I used the truck yesterday and was doing some serious crawling with a buddy. He has a novak system in his and up until yesterday My Xcelorin system kept right up with the Novak. Once again the truck stopped moving and began to buzz. I let off and the truck rolled back about an inch and then it powered through ok. The buzzing and stopping got worse so I quit until I could get a really good look at what was happening.
I thought maybe a tooth in the tranny stripped so I took it apart and there was nothing wrong inside. All gears looked great. They should the truck is only a couple weeks older than the Xcelorin system.
I crawled across the couch and it buzzed again. I stopped and looked closely at what was happening. The motor was buzzing and the pinion was moving moving back and forth very quickly about an 1/8 of an inch. I let off the throttle the truck rolled back a bit and then it crawled over the obstacle. Now even rolling across a level floor at half throttle or even full throttle ( it doesn't matter what speed now) it will buzz for a split second and keep moving.
Any ideas here? I've been reading about Xcelorin systems and the problems people have encountered. Does this sound like bad sensors inside the motor? :confused:
Dinkin around with it it is the sensor wire going into the motor. Since the motor is discontinued nothing can be done.
LOSI please come up with a new and improved brushless setup for the mini crawler.
