    Power Wheels Racing

    Alright, some of you are familiar with this and some are not: http://www.powerracingseries.org/ A lot of my friends compete and I'm considering giving it a shot this year. The rules are a little tricky, the total project has to cost less than $500 but that doesnt include the initial power...

    Burning up brushless ESCs

    Is the consensus that the Phoenix Ice HV 160 is the best speed controller out there for RC builds? I've read a few people talking about burning them up under acceleration.

    Best Long Range Option

    Hi all; I'm currently building the dead-sexy (at least I think so) Delta Wolf trike from Atomic Zombie. It looks like this in case you've not seen it: From my previous electric project, I have two 1000 watt Unite motors and controllers from TNCScooters as well as four 85 amp hour deep cycle...
