mamba max problem

[rcsammy]

i have two MMs which i run and have problems with
the first is in my TC3 on a VXL motor on 3S, it will go forwards fine but i have no brake and no reverse, i have tried resetting all settings, and an older firmware version, i tried to calibrate it and it takes the forwards setting fine but i get a flashing red light after that and it wont accept any reverse or brake settings

the second is in my rustler on a Neu 1506 on 3S, i was just running round on some grass earlier today, hardly into the run and it just stopped, no forwards or reverse
when first turned on the motor will run for a few seconds then it dies again, cant work out whats wrong
tried a different motor and its the same and i have tried a different battery too

thanks for any help

1st one sounds like a radio issue- check the throttle trim and epa settings.

2nd is odd, could be an lvc setting issue (they have been known to randomly reset themselves on rare occasions)- hook it up to the castlelink and take a look. Unless its a bad switch, but then it would be intermitant on/off periods etc..

ive checked the radio settings for both of them, reset the profiles to default to make sure aswell but no luck

ive had it on castle link, turned the lvc off and tried it but it was the same
cant be switch as its not got one

cant work it out at all, hope i wont have to send them back... really weird to have two do this in seperate setups one after the other
