Core Pace 45R ESC

[i4n]

I've just built up a SS and for convenience purchased the Core GT12 power pack.

Everything works well, except that when I brake or reverse the ESC 'pulses' the motor varying the speed of reverse or the amount of braking.

I'm using it completely as stock, Speed Passion 13.5R and the Core 1S LiPo.

I've tried playing around with the settings using the settings box but whatever I have done to it the pulsing has remained. If I disable reverse the pulsing is still there on braking. I've reset the ESC to factory setting and it still does the same.

I have fully charged the LiPo and replaced the sensor lead (making sure it's definitely in the motor and ESC) as well as making sure that the ABS function is turned off on the Tx. The only thing I haven't done is put a 2S (but I can't see how this would make any difference as the ESC is designed to be run on 1S).

I've emailed Schumacher support to ask the question (never having had one of these ESC before I don't know if this is normal or not) but thought I'd pop a post up here asking if anyone else has the same behaviour from their ESC?

Cheers,

Ian
