mamba max wont calibrate

[hailmick]

check your xtals firstly
your battery should be fine as the esc is getting power its just not calibrated
bec maybe?
any dead cells on the battery? as mm only works 6 to 12 one deadcell your out the game
check your voltage may give an indication
have you got another receiver to try or xtals
(last resort) try a rx pack if you have one just make sure you remove the red wire from the esc input plug the one that goes into reciever
are running brushless or brushed as you dont state it
if you are using a brushless this may sound dumb but touch the male connecters from motor with the others on the motor
then try it
sorry but make sure you are calibrating it right
i thought i new it all and rushed to calibrate and i had the same problem as you but all i did was rubbed all 3 motor wires together and checked all connectors (thats unplugging them then plugging them all back in) then calibrated it

lets us know how you go
