Hobbywing max rsc or motor problem? Unsure which

[Craigyboy83]

Been running my Hoboa hyper Vs RTR for a few months (pretty sure it’s a hobbywing max 8 esc in the RTR), probably about 30 packs or more through it but had a little issue today I couldn’t resolve. The car stopped running while I was driving and wouldn’t go again, when I unplugged the battery and plugged it back in the motor didn’t beep for the cell count and now the red and green lights stay solid lit on the ESC, I thought it was maybe the pack but I’ve tried 2 other fully charged 4s packs and it still doesn’t work, fan comes on at the esc but it seems like it maybe the motor at fault? It did have an intermittent problem previously where occasionally it just wouldn’t pick up throttle input for a split second but I hadn’t had that in ages, not sure if it could be connected. Any input from those wiser than me would be greatly appreciated!

it is a max 8

Do you have another brushless motor you can try ?

it really doesnt matter what brushless motor it is so long as its rated at the volts of your packs 

does the motor spin freely by hand ?

could it be thermal limits of esc or motor ?

I don’t have another moto mr to try but even after sitting for a few hours it’s still no beeping for the battery. The car still seems to roll freely, I should maybe take the motor out and spin it on its own and see

if cars rolling freely when pushed theres nothing stuck in motor or drive train 

 

Sorry but not sure what else to suggest 

[Craigyboy83]

Thanks for the suggestions stormbringer. Its definitely is a strange one, just to grind to halt like that. I’ll maybe pick up a new max8 motor and esc combo and see just replace the whole lot.

Sounds like an expired ESC, it happens even when it's been looked after.

can you reset the esc?, hold the button and turn it on it will chirp, try disconnecting a motor wire any chirps?

The Esc won’t let me reset, holding the set button does along with switching on does nothing, I’ll try a pulling motor wire and see what happens.

time to spend some £££ on some new kit I think

The motor might be fine, they're more robust than the ESC.
