I think it's great that you are doing what you are doing and I think it's great why you are doing it.
If you could produce 5-20 a year, think of all the people that you could lend mobility to.. Get this one done for your son, and try to find an investor. Just my 2 cents..
VERY nice work, by the way.

Hi first I would like to say this is one hell of a kart. Looks more like a production than diy.
I understand you want it to serve for couple of years since you made it larger than needed for a 4 year. Probably dad's want's a ride too..
Which batteries are you planing? deep cycle?
Is there a "master" circuit that controls both controllers?
How do you make sure they will have exactly the same speed on straight ride?
And please more pics...

Newspaper article about the Scarab electric car
Hello everyone
Thanks for the kudos. We set out to make a wheelchair in the shape of a go-kart that would give my son off-road mobility well into his adult life and therefore we gave it everything. In my situation I am sure you guys would have done the same.
Hi Baer
We separate the joystick output into forward/reverse signals and left/right signals. The FR signal goes to a dual motor controller that handles 75A cont per channel and 220A crank. The controller has various accelleration curve options and it will always stop the motor briefly between forward and reverse. The LR signal goes thru a bit of electronics that we designed to a server motor attached to the steering rack via two sprockets and a chain. We have a feedback mechanism between the motor and our electronics so that the brain box knows where the steering rack is at all times. We will install a manual trim switch that will make minor corrections if the vehicle doesn't track straight when the joystick is centered. This will counter any minor differences in the speed of the backwheels. We could also use the controller in skid/steer mode but that would have to be controlled quite carefully.
We will start some serious testing in about two weeks time and I will post more pictures and links to videos.
The local newspaper learned about our project and published the article below.
Good luck with your projects, electric is the way to go!

Hey Clint....Good job!! I like the comment the article made about the boerewors curtain. I think it is great that you have done this for your son. It also sounds as if there are going to be loads of gadgets on board
Hi landuse
Thanks.Other gadgets I haven't spoken about include a headrest with fingers that cradle his neck and his head. They are malleable and wrap around to provide lateral support. I am also putting a hooter under the nose cone which will be attached to a piece of cord and a pull-to-make switch so that he can yank on it like a train driver.
If you are in Cape Town on 25 Feb come along on his first beach walk.

Congratulations on the good publicity! You built a very unique and practical machine and you should be applauded. Good on ya!
I have to confess, this made me laugh. HARD!
You see, although what you know as a hooter, I know as a "horn". The problem is, around here, "hooter" is slang for breast. So- Tugging on a hooter.... LOL. Sorry. I got a sick mind. I admit it.
Great build!

Yup....we have hooters installed in all our cars, and push them often. LOL
I wish I could. I hope it all goes well, and your son loves it. I am sure he will though.
I haven't been to Cape Town in About 10 years now. I studied and lived in Stellenbosh for about 7 years. I also worked at Delheim Wine Farm. I don't know if you have been there before.
Scarab body panels
Hi
Progress is picking up after a bit of inactivity. The mudguards and the nose cone have received their paint and their graphics are now ready to fit. Testing of the car to begin any day now....

Nice!
Picture of frame
Thanks chaps.
The tubes are stainless steel and very difficult to shape so we had the bending work done for us by an engineering company. My son likes the shape of the Ariel Atom and this was our design inspiration. I have attached a better picture of the frame, in the background you can just make out the breakneck trailer that we purchased to transport the Scarab.
Adios
