Chris, mtoniks havnt done an external BEC for a while now, i cant remember seeing one.
the motor is pulling .5A out of water.!
just tried my new useless 15A, with the esc enabled, the rest of the functuions work, but not the motor.(no LEDS)
my old 15A Mtronic worked for a bit, then kept cutting out. cant use it though as there is a noticable time lag between stop and forward, and i can not program it out. the old one also cuts out after 20 mins or so, but not failed totaly, wheras the new one has stoped workin the motor.
i hate speed controllers, they always fail on me, eventualy.
i am running 4 x 6v packs. 2 in series to give me 2 packs of 12v. one feeds the motor, the other the dive unit. the radio is fed from the dive battery of a receiver fly lead at 6v. the Mtronics has the red wire disconected.
fed up
