Electric Race Kart

[jhb]

I am building an electric race kart and was wondering what motor, batteries, and controller I should use.

Thanks,
Jeff

Biggest you can lift, and biggest you can afford


"Race" implies an organized event with specs for what they allow. Without those specs, or some idea how you'll be using it, its impossable to give a recomendation other than "Go Big 'n Go Fast"

As of right now I just want to get a fast kart that I can play around with on the track. There are no electric race kart race series (at least right now)

All the technology exists for a fast race kart...BUT..
the current state of battery technology will mean you either have a very limited "Track Time" ..5 to 10 min at most, ..OR you end up with a very heavy battery pack (50+ kg of LiPo) to allow a 20 min run time together with an expensive fast recharge system or spare ( $4k+) packs to swap between runs.

Old Zero X/MX drivetrains are awesome. The zero guys have built a lot of em and they're a riot for stealthy parking lot races. Perm or agni motor, with an alltrax AXE at 400amps and a zero battery = fun. Giant smoky burnouts, doughnuts and figure 8's are the norm. I'll dig up some pics and vids.

that would be greats, thanks

After a dozen races, some with 5-6 karts running simultaneously, this is the only crappy footage I could find... I don't think they really convey the sense of speed and acceleration these karts posses. 10-15 minutes of hard racing leaves you sore and sweaty Maybe we'll stage a race with a dedicated photographer soon.






Yes, that's our beloved Luke, burning the tires off the wheels...

Sweet im working on this as well... When I get colossus running... But for now I just got a westinghouse 4.5hp 36v motor im sure i can push it a bit further. I will be building one for off road and then I want to get a shifter!!!

[jhb]

Thats pretty cool. What type of top speeds can you hit? I'd assume they are pretty quick in acceleration with the maximum torc being at 0 rpm.

intresting... I may go try and check this out. It seems like a lot of fun.
