Radio controlling a Mobility Scooter: Need help finding out what kind of ESC I need, and where to get one.

I have a 48-inch long fiberglass "F250" style truck body.

 I want to turn it into a rideable car, but ALSO an RC car!

 I am using the remains of a 24 volt Mobility Scooter (rear suspension, motor, drivetrain, and differential axle, and part of the chassis) with slightly larger wheels and tires.  Steering will be actuated with a 12-volt motor and drive out of a car seat that had electric adjustments.

I want to be able to set the original seat from the mobility scooter back into it's original place through a hole int he bed and sit on it and hold a WIRED controller in my hand to operate both speed AND steering.  I want also to be able to remove the seat, unplug the wires controller, turn on an RC receiver and transmitter, and drive the vehicle by remote.  I am NOT building an autonomous robot or anything hugely techie like that, just a sort-of cross between an RC car and a gocart.  It doesn't need to be any faster or more powerful than the original mobility scooter either, so all I really need is batteries and a motor controller..  Controlling the steering actuator will be done with some limit switches and relays simply, that's not-at-all a problem at this point.

 I need a battery set (two garden-tractor batteries?  I don't think I can afford SLAs or anything high-tech right now...) and an ESC and honestly have no idea what I need or where to find it.  I do not know exactly what the amperage of the motor is, but I have a car-battery stress-tester as well as a multi-meter device and with someone's help I am sure I can figure out how to get an accurate measurement of current from the motor.

 I would love for someone to help me out with this project!!?  If you have a business and it would benefit you, I WILL put your name ON the truck like a sponsor!!  i want to be able to take it to certain garden-tractor shows and maybe even run it in a local parade or two.  I want it to be seen.

Try "Dimension engineering" for a good ESC.

See Canucksgirl's link for actual build ideas. For what you describe, it'll probably be much easier to wire the thing as a pure RC controlled device. When you're riding on top, just have a place to clamp on the RC controller and drive it that way. Having duplicate controls, and needing to switch between them, is more likely to lead to failures.

Have you looked at some of the "Related". -------->

There's a "Build a HUGE RC MONSTER TRUCK..." that does seem to address some of the questions you have.

It may be worth a look.
