i bought a magic pie 3 with internal controller, lastest a few weeks until it rained, controller failure, decided it was too heavy anyway so i replaced it with a smart pie, lasted a few weeks until it rained, replaced the faulty controller with a new one which turned out to be dead straight out of the box, i now use a bafang, i'm considering trying an external controller on the smart pie one day, when i've calmed down a bit (i still shudder from the experience) anybody else had this problem? its a nice motor with seemingly shoddy electrics
