I just received my speed passion rs2, I got it for the girlfriend. I read the manual, cut off the silly plug the esc comes with and soldered on a xt-60. Plugged in a cheap 2s lipo and took it for a spin, the power delivery seemed a little odd. But I figured it was a $160 truck, and not a $160 esc so honestly I didn't expect it to be as quick as it was. I checked the temps after about 5 minutes of running up and down the driveway, had 115°f on the motor and 105°f on the esc. I was thinking about gearing up. Then me and the girlfriend went to my buddy's track to see how well it flies. When we got there I plugged a fresh 2s lipo and handed her the controls. I checked the temps after 5 minutes again, both were around 100°f. Set it back on the track , she takes two more laps and the truck just simply stopped moving. Walk up to the truck, notice that the fan wasn't running. Pulled the body off, the fan was to hot to touch And it had shorted itself. But the esc was still cool. After troubleshooting I've determined that every component is good except for the esc and the fan. I tried many times to set the endpoint, the motor chimes and it acts like it excepts it. But nothing. Any advice for me? Anything I should try?
