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.

Dream on! they are not even looking after the forum, my last posts dates back from last year...Xcelorin are dead...way dead and no they are not called phoenix!

when you see companies like Orion and Speed Passion using Hobbywings, it could be a good idea for Losi too.
