Help,

i tested my b44 outside with an lrp sphere 07 competition + fan cooling set, it ran fine, didnt get hot but then stopped i just assumed batteries run out. Another set of batteries a day later and it revs up fine whilst holding it but put it on the floor it goes 5m then stops suddenly with steering servo still working. The yellow light flashes on the speedo cant remember if any others were maybe blue? It hasn't got hot cos it hasnt gone anywhere.

The controller and motor are both brand new. vector x-11 5.5

Any ideas, experience required as this brushless stuff is new to me

That'll be the one, I have the same setup ans it always cuts out under heavey acceleration if its in LIPO mode when I use NIMH.

Thankyou for your quick reply, as usual if i had read the manual properly i would of seen the recommended setup was function 2 4-7 cell nimh. It also would of helped if the batteries i had put in were charged!!!! I didnt realise it had a low voltage cut-off i thought that was only for lipo's.

Thanks again i owe u.

Yeah I use it as a way of working out how knackered my batteries are, if they cutoff while fully charged I know I'm in trouble!!!
