OK I finally got my main chassi for my xxx-s in the mail and put my car back together exactly the way it was when I took it apart. A few kids in my neighborhood have cars and wanted to race me and finally I could because I had my car back together. One of them has a the electric 4-tec and the other the nitro 4-tec, these are pretty fast cars so I knew I would need to be faster. We were dragging by the way.
So I popped a 28 tooth pinion in my car which made the gear ratio 5.75, opposed to the 6.71 ratio I had before. This is quite a hop, and my car very fast. Yesterday was also very hot here near chicago (90 or something and about 100% humidity which made it feel, according to the weather man, 110 degrees). Just standing outside for 10 minutes I started to sweat.
We raced a few times and I beat them everytime, I even gave them a handicap and still won. However I think I damaged my esc. My motor was a little warmer than usual which I blamed the weather for, but my esc was really hot, a lot hotter than normal. Also where the battery connects to my esc the wire was really hot too. I dont know why?
And since I had it geared so high wouldn't my motor be the first thing to fry? I took it out today with the 6.71 gear ratio and it ran fine for about 2 minutes then pretty quickly got slower and slower until it wouldn't go. It was a fully charged battery too. My motor was just warm but my esc was really hot again.
Is there a way I can fix this, or do I need to get a new esc? Also why did my esc get hot and not my motor? And how come it only goes slow (by slow I mean you could walk about the same speed as it)?
And yes I realize I was stupid for gearing it that high on probably the hottest day of the summer.
p.s. I was using a gm3 esc. with a 19 turn motor
