I got my first 2.4ghz car today. I set my controller per KO PROPO recommendations, paired the car to the transmitter and put it on the track. Worked great. Ran the car till the batteries died down. Shut off everything and put a new set in. I noticed one of the motor caps sticking straight out from the motor and pushed it down. I put it back on the track and only had steering. So I tightened the motor leads and tried again. This time I got smoke. So I shut it off quick. I checked to make sure the motor leads weren't touching the cap/diode deal in between the positive and negative leads and powered it back on. I have full power forward but, reverse doesn't work. It actually rotates the motor forward slowly and starts smoking the FET on the left. Both the top and bottom FET have bubbles. So I'm guessing I blew the reverse FETs. I would like to know how. When I pushed the motor cap down and out of the way did I short it? I can't figure out what I did. I really don't want this to happen again. So any insight would be nice.
