Just a little problem im having with my stigma fly. It slows down like ive droped the volts to about 7 and then picks back up again ? I run it on an Ekon clip cord and a Micky Sharpz power supply (I have 2 and tried both) and usualy 7 to 15 curved mags. Cuz the motor can turn around on the back I wonder if ive ran it with the clip cord the wrong way round ? would this damage the motor ?. Any advice would be very welcome for a rotary newb

Regards,
Dallas.
