going brushless (savage x 4.6)

i got a rough prototype running today. i mounted the motor mount, the $30 esc i got from hobbycity, 2 25c 5000mah 3s lipos in series, and the KB motor. i plugged it in and i got no response. i then remembered that the esc has no BEC, so i threw my orion 1600mah rx pack in and off it went. after a solid 10 mins of speed runs with a top speed of about 50-55mph, the motor was at 170F, the esc was at 160F, and the batts were at 95F. the ambient tempurature was 90F.

i never did achieve top speed because the stock savage x tires balloon a lot and the truck was too unstable. i actually flipped the truck over with the esc sticking out of the top of the plastic roll cage and i already got a nice dose of road rash on it.

the charger i am using is the turnigy accucell-6. it works great. very accurate.

i did not lock the gears. it was able to shift and so far, there are no problems with the tranny. i will post pics and possibly a video tomorrow or monday.

Nice,mind showing the link for the esc you got?
Also what is the gearing?

Sounds like your gearing is a bit high with those temps. Drop a few teeth on the pinion.
