Viper Motor/ESC wont run! Help!
 

Hi. Just come back from my weekly club meet and not very happy.

I'm running a TLR 22 fitted with Viper ESC and sensored 7.5t motor. On heat 2 the car started to run really slow half way through and then after my stint of marshalling, i took the car back to the table, powered it up and it wouldn't run. It powers up and the lights all flash as they should and I re-calibrated the controller, but the motor still didnt turn unless i turned the back wheels, then it ran but at a slower pace. Once i let go of the trigger, it stopped and wouldnt turn again unless i moved the wheels again.
I recharged my saddle pack, but still didnt help.
I connected the programme card and loaded up a new profile, but still nothing unless i start the wheels moving myself, and then only at less than half speed (if that!!).
My charger didnt say anything was wrong with the batteries so am i using the programme card wrong or something?
When i pull the throttle, the LEDs change as they should so i know the radio is working.
Can anyone help please??

Sounds like a motor/sensor problem, try a different motor if you have one or a different sensor wire.

yeah, sounds like a sensor in the motor -- try a different motor, different cable.

cheers guys. It was a loose cable at the ESC - middle wire to the motor. Got it sorted for now but will need to strip and resolder all cables as its very tight to get in to get a decent weld otherwise.
But all good!

I need some new saddle lipos - whats the max mah/C rating I can use?

They can run with any 2s on the market. I've used 100C packs, no issues.
