will be placing the batteries 2 x 12v 15ah or 12v 22ah plenty of room there, the low centre of gravity and balances ride. probably will end up putting another battery under the hood for a 36v upgrade.

Doing it right!

You should seriously consider building in a roll bar loop into the frame. Even through the cars CG is low, the kid driving it has a high CG, sticky rubber, short wheelbase, TONS OF POWER = very high rollover risk. With your skills it wouldn't take much to do something like this

That's so much fun it should be illegal! :P Really good to see him wearing a helmet, safety first cause kids are a hassle to replace :shock: :? Ok bad joke. Good to see you setting the example! :D

This car has to be my favourite build and Sunny's to by the looks of it. No helmet, no ride policy with these cars that are beyond the 12v range in our household.also if any kid breaks the rules there license gets suspended for the weekend.happens from time to time on serious breaches like crossing the road with out being told to etc etc. @toycrusher

Sure looks like he can drive with out the use of a brake, but does it have one, and if so how does it work?

No mechanical brake just the regen brake in the controller,back off the gas pedal and it kicks in. Simple and very effective.these are the controllers I use,Australian made.

So it's a similar situation as stock?
Motors generated power build up fighting the rotation.
But I suppose it is dependant upon the motor used Huh?

Sort of same principal but the regen braking principal actually puts power back into the battery. But on the small scale as these rides it doesn't generate power but applies a braking function.

pretty sure it was B @redline,i only hook up the reverse switch and bridge the on/off switch as i run a isolater on the positive line from the battery to the controller.

Ahh nice ... you run just the single motor right? It should run dual motors ok though?

First of all, really neat build. Love it.
So, interested in these controllers you are using also.
Looks like a neat way to eliminate a lot of the relays used with the standard ESC method folks are applying.
Do you need one of those special golf cart accelerator pedals that provide a SPST contact on release of the accelerator, or is all this done from inside the controller based on the hall sensor input (or lack thereof).
For applications with multiple motors have you tried to run series for reverse and low speed or do you run a single speed for all gears?

the controller can be used with twist throttles or foot pedals,yes they are simple for wiring and the regen braking eleminatesa second pedal.reverse function is simple as well but the speed can not be adjusted.ive tryed putting a pentimeter on the control line of the pedal but it didnt do anything.why? i'm not sure. dual motors is a easy set up using the controller.check out the video on motion dynmaics page it has the run down on the controller.
