Hi , I’m interested in the qs205 . What winding is it? 3.5 turn or 5turn ? Or do you know the kv? I’m looking for a high torque version 9.3kv , I’m not interested in the high speed version (14kv ) can you post to UK ? Many thanks Nick

I'm having the same problems, First problem was the motor over temperature, which was sorted by shorting ( I also used a resistor in series just in case). the white wire to ground on the hall plug .

Finally my sabvoton has arrived , but I'm getting a motor over temperature system error in the software There doesn't seem to be anywhere in the software to disable this , so it won't let me run the hall auto map . There is a white temp wire in the hall plug , how is this wired , can I bypass...
