Brushless Broke?

[antnee]

Got a strange problem with my brushless,

I'm running a Mamba Max esc with a Orion Vortex 6.5,

It had been working fine untill the last round on friday, it just went slow and stopped. We took it apart and thought it was cos it wasnt shimmed right, sorted the shims out and its the same

It turns over a VERY low throttle then just stutters, and the wires get hot too

Idea's anyone?

[antnee]

anyone?

[Wraggy]

sounds like your speedo has thermalled out ???

[antnee]

Thermalled out as in non-reversable damage?

Still didn't work when I tried it yesterday.

Do you have access to another motor? It could be something has come a-drift internally and something is shorting out (have a look, especially the sensor wire area), but only by testing the ESC with a different motor would tell if it is the ESC or motor at fault.

yeah this seems to happen to some of the LRP ones (ive had one do that anyway and know of another that has done the same )
so may be the case with Mamba ones ??
do you get a warranty with them ??
if so i would try them 1st ..??

bought motor and esc second hand

How the hell did you do manage that?? Indoors, 5.5, over geared (well over the recomended ratio by 2 teeth) and run till the 4200s nearly dumped in practice and still, 18 flashes (5 is thermal failure region!!)

it may of been down to a fault with the speedo in the 1st place as since then ive ran the same gearing and everything else and its no wjere near thermalling ..

Do orion have a UK base/repairers?

[SimonW]

My GTB has just squeaked and popped with a puff of smoke when i switched it on..... Wierd.

[josh_smaxx]

If its the speedo, just send it to castle for repair, there great with customer service, even if it takes a while

[antnee]

i think its the motor as the esc runs brushed motors still

[josh_smaxx]

Ye but brushed motors dont need a sensor wire i had the same problem and ended up havign to sheel out for a GTB but mine was just stuttering, it did sort of work.
