I have spent hours trying to pick out the right electronics for my longboard trying to find the motor that best suites my needs. I need a nice balance between range and power output. I have been using http://www.howtomakeanelectricskateboard.wordpress.com for some guidance on picking my motor and esc. I am using the same motor but the esc that he used (and that I was about to use) was fried while he was riding. I picked out another one with a high burst current rating.
I plan on plugging the motor into the esc along with the battery and plugging the esc into the arduino (escs are fairly easy to control with an arduino). I’ll then plug the wireless wii nunchuck into the arduino and use that to control throttle and lights. I also plan on installing an emergency kill switch that I can hit with my foot.

Maybe some EL lighting and definitely headlights
BATTERIES I haven’t picked any out yet but I am going to use 25c 6s batteries.
