BK Controller set up problem - RC-Monster Forums

well I tried it with the 3000 pack I have fully charged as well as without putting the black jumper back on and it's still doing the same thing.

The connector that came off is the one close the front of the board edge.

If there was a problem with it would it still let me go through the steps of programming it? For instance would it still beep and everything if there was a problem with the connector?

Every time you power it up it would be in programming mode, so I am not sure what ESC would do...is it normal operational mode probably not, so I think you need restore this pin first and then continue with testing. Now I am curious what is going on with built-in BEC, is it still alive or dead, after fighting with UBEC (5V vs. 6V).

I do not have BK ESC on hand to verify operation with open jumper.

I received your package, your motor has too much play inside motor-can and bearing are not as smooth. Your ESC need some attention, I will try to tune it up and let you know later.
Nice packaging, have you send me additional packages?

Hi... not to barge in... but I had the same problem with my 12020 and 8Xl setup just last night.. a couple days ago I ran the truck without the cover and flipped it.. the motor made good contact with the ground (concrete

) and bent the motor mount... at first, the motor would not rotate by hand, then all of sudden it did..

Then last night after a little clean up and a change of the motor mount.. I plugged everything back together and did a test... the motor started cogging violently, then I saw the shrink on the 12020 started to tear away.. I pugged everything out, and found that the temp on the motor and controller was very very high..

I went to the BK site to see if I could find any info that would explain what was happening... and I found this:

"Interruption of one motor phase
Motor does not rev up, only jerks back and forth. Disconnect battery immediately, motor can be severely damaged!"

http://www.bk-electronics.com/bk_eng.html

I opened the motor and notice the magnet was making some contact with the
the coils... the bearings also felt a little rough..

Just my 2 cents

Alien..
