Broken electric motor jetboard

Continuing the discussion from Electric board will not start mosfet dead?:

Hallo what is the problem with yours ?? My handgrip flashes 13x. I have taken out the complete motor . But all the electronics in de motor are fully sealed . How do you open it to replace the broken part??

problem with mine is that the prop started going backwards !
Been waiting for 4 months for a programming cable to come from China ti reflash the ESC

Hallo did you take your motor out of the board?? I removed mine but all the electronics are sealed in. So i hope the chinese company will send me a new motor or parts to fix it. I live in Amsterdam where do you live??
