Losi Xcelorin LOSB9500 problem

[DanB4]

Help!

Trying to set-up my Xcelorin speedo with packaged 6.5 Losi sensored motor - have followed the instructions several times to calibrate to transmitter and I do have steering BUT just cannot get throttle....only thing which gives throttle is if I manually spin the motor pinion by hand then it revs up to full rpm, braking on the tx stops it then full brake gives full throttle again....very strange and annoying.

I have tried 3 different sensor leads, which I know work, so have ruled that out.

Is this a sensor issue with the motor or could it be the ESC?

I have another 6.5 motor and another brushless speedo so will try mixing and matching to fault find but before I switch on the soldering iron has anyone got any bright ideas?

Thanks,

Dan
