Remote Controlled Gokart, What do you think?

[camarossnitro]

I have a Manco Dingo. I have rigged it up with a predator 346. I want to make it remote-controlled. I have a Traxxas 2.4 System ready. I can get 3 servos within a few weeks. What do u thing? :biggrinjester:

 

[whiteoakraider]

do it !!

 

[carter]

one servo to the throttle, one big one on the steering wheel, another on the brakes, your set, except maybe some kind of pneumatic piston on the brakes.

 

[chris_the_poser]

Your going to need good servos for steering and braking other than that go for it

 

[Jcotz]

I am assuming you have a basic steering setup at the moment. In which case, you might have to make or get some sort of power steering setup, because I don't think a servo would be able to control the steering. (Unless you have a very heavy duty one).

 

[carter]

you also might be better off using some sort of pneumatic piston for the break pedal control, because I don't think a servo would be able to push a drum break setup well enough to stop a cart, also you might want to use a very large servo for your steering, or attach some form of gear to the wheel and use a large reduction on it. and make sure you set up some form of emergency fail safe, if you suddenly lose connection while gunning it, it might continue to just keep going till it hits something or someone, or runs out of gas, or flips

I am definitey using a pneumatic piston of the brake pedal. One of the smaller servos will be mounted on the bottom. There is another one will do as the fail-safe. A powerful servo will be mounted on the bottom of the steering rod.

What servo will you use for steering ?

when i do power wheels jeeps i have to use 2 1/4 scale servos to turn the wheels.

you will need a very powerful one for a kart

 

[camarossnitro]

I am using http://www.hobbypartz.com/servo-mg90s.html this

 

[camarossnitro]

I am using a setup of 2 servos with steel cable to pull the throttle

 

[carter]

and I assume that you'll be using this on 6V for the extra output?

 

[ML-TOYS]

That servo will not do it

[carter]

wow, that has alot more torque than the ones he suggested

 

[camarossnitro]

yeah. I need one of those. I have several batteries.

 

[camarossnitro]

Oh yes, Where can i get a hydralic piston?

 

[carter]

go with pneumatic, it runs on air pressure, much less complicated

Could always drop some bucks and use

Search the forum, I believe this has been discussed before. As of right now I can remember seeing a remote control go kart in a PM or POP SCI magazine. I also came across a website with a remote control buggy that was about go kart size.
