Chris, how is it going? Did you push the motor to its limits already?
yeah i pushed it, and the windings burned out after about 10 mins. i should have monitored the current and temps while using the board.
oh well. i contacted the company who makes the motor, and they are very helpful. they say they can produce a motor with more copper to keep the temps under control. but its chinese new years, and they wont be able to start production again until the 24th, then it will be probably about 2 weeks to arrive in romania. then probably a month in romanian customs office. anyway, im feeling impatient, so i just ordered a "lehner torqstar 3 7050"
i think the chinese motor would probably be fine. but my 79mm prop and 70mm pitch are a little aggressive for it. i have now redesigned the prop to be 79mm dia and 55mm pitch, and that coupled with a custom chinese motor would probably have been great. but unfortuately, thats not how it worked out for me.
for now the chinese esc is still working, and it has some kind of protection on it which is good!
