I was using a mild BL in my Zerda but it was still too much for the all belt transmission so I decided to go back to a brushed setup and chose a Goolrc 17t motor with the same pinion/pulley a 20 tooth one , after 5 min running it was so hot it desoldered the negative wire

, so I went down to an 18t pinion/pulley , after 5 min it was up to 169C

so I went down to a 16t pinion the lowest that came with the car and try'd again and after 5min I still had 155C . The belt tension is not over tight , infact I still had a little slip on the last run

oh I'm running 2s lipo by the way .
Now the question is this , is a 17t motor just too much in the Zerda , too heavy ? Too much transmission drag with the dual belt drive ? Or do I have a duff motor ? , the motor is brand new .
If a jobs not worth doing then its certainly not worth doing well.
A problem shared is a problem halved but an advantage shared is no advantage at all.
