Well I raced in the A Main, everything was fine all night. I took 2nd in the main and went to my pit, put my car down, went to marshall for the next race. I marshall, come back to my pit, smell something, smell around, seems its coming from somewhere in my pit. Not my chargers or anything, then I see it.
Some smoke was coming from my car, near the battery/motor area (XRAY T2). It was not alot of smoke, just a little bit, but you could smell it bad and so I found sissors very fast and cut my ESC wires off the battery and undid my strap, got the pack out of the car ASAP. Put the pack on the fan to let it cool. It was very hot.
The thing is, I cannot find one mark on the cells (3300's) or anywhere on my chassis where they would short out. My cells are shrink wraped and I been running good all night, although this is the first time I used this pack. These are not race batteries, there oversized ones, not sure what kind, but they were good cells. I just re-shrinked them too. There were two small "scraps or spark" marks, very small on the end edge of one cell, it may have shorted out with some spot in the battery slot area.
Now I think it may have been my motor that fried out, but it is a BRAND new (just bought yesterday and ran only a handful of times) Team Orion V2 19T Mod. I was running a 25 Pinon w/ 84-48 Spur. It seemed great all night, and the temp was like 122. People say for a 19T my car was SLOW on the stright away, well, fast, but slow for the motor it is. So I take it the gearing is more than fine for it, even under-geared. My ratio is 5.75 right now and people on this forum told me to be under 6 with my motor.
So I think it might be my battery slots. I don't think I sanded/filed them down enough. I just don't know how much to file them down without going too far.
Anyways, any ideas what may have sparked this? You think I ruined my motor, pack, and possibly melted the chassis (even though it don't look like it)? It looks fine, Im throwing that pack out though, I did't like it anyways and I don't know why I even ran it for the Main. Anymore ideas on the gearing for this motor, anyone want to share some helpful infomation to me to prevent anything like this from happening agian?
This is my first car where I had to file the chassis down, glue it, etc...I used to have a FT TC4 which came pre-sanded down from factory. Anyway of telling if it was the pack that is shot without putting it on my car agian or charger and it starting on fire!
Thanks for any of the help you can give me.
On a positive note, my car is dialed
