I have installed a JP EnerG C60 0/R670 (50-20) and am trying to programm the Hawk FS BL100 controller. It asks for how many poles. Does anyone know the number of poles, please? As i cannot get it to work 😡

I have a hawk BL60 and when setting up left it at 2 poles as I couldn’t find the number of poles on the Graupner HPD 2920 4000
And it works ok have fitted to of these in my crash Tender and both worked fine although I find it a bit fast with the 11 volt lipos

Thanks again been searching all over for that info. Got my Crash Tender completed just setting up the the smaller 7.4volt lipo’s if ok will show the photos.
Did find with the Hawk escs set up the forward stop and reverse settings as per the instructions and the motors worked immediately only had to go into the parameters to set the reverse. So you may have another problem on your setup and not the hawk esc

Hi Chris, are you sure that part /model number is correct?
Can't find it anywhere. Have twigged it must be a J Perkin motor but can't find anything on a C60 type.🤔
