The Brushless Jato entered it's first race last night. It was a less-then-stellar performance....
2 qualifiers and the main.
Qualifier 1 - on the second lap my motor mount moved and disengaged the pinion from the spur...
Qualifier 2 - on the first lap the pinion actually fell off...I didn't find it until the end of the night. At least the shop had a few 32-pitch pinions that let me get it back up and running. I hadn't lost a pinion or even had one come loose in all the testing...go figure.
Main - about 3 minutes into the race the motor mount moved again...game over, man.:C:
The bonus is that I now know a few important things.
1. This battery (2s), motor (lehner basic xl4200), and speed controller (MGM12012) is a GREAT combination for racing the Brushless Jato. Controller temp never went over 108 and the motor stayed only slightly warm. It has too much power to hit full throttle on the 96' straight, so I have no need to make it go faster. This is the same setup I GPS'ed at 36.8MPH.
2. The problems I had are easily fixed (once I get to work on it, that is). I already put a drop of threadlock on the pinion. Now I just need to get the motor mount to stop moving.
3. I need to work on reducing weight overall, focusing on moving the weight that remains down and to the back. It's still about 1lb. heavier than a "normal" electric stadium truck.
I hope to get it back up and running reliably and see if I can actually race again next week.

Electronics run on smoke... if you let the smoke out, they stop working.
