Help with unusual project - large car/dolly to haul 60+ lbs
Hi all,
New here, and zero RC experience.
I need to build a larger RC vehicle to haul weights of about 60+ lbs around.
Here are basic specs/requirements:
- electric motor
- speed 8 to 12 mph
- chassis about 15" x 30"
- no need for suspension at this time
- steering not absolutely necessary. I may end up building some with and some without steering.
- easy battery change. Motor needs to run reasonable amount of time, and when battery dies, I need to be able to switch to a fresh battery as quickly as reasonably possible. (less than 3 minutes, but <1m is far better. "Pull out, push in, done" procedure preferred.
I was thinking of starting with something like a "power wheels" or "kid trax" toy, hook it up to a controller.
Does anyone know if such motors/chassis combos exists on the commercial market? And if not what is the closest, and who can help me with it?
Thanks.

The fighting robot crowd will probably have more for you than we will. Years ago, they mostly used wheelchair motors, but there may be something better now. I can't think of any off the shelf RC gear made for anything that big, but it wouldn't be so hard to copy the steering setup of an RC10 or Traxxas truck.

If you want the parts from a ride on toy, browse Craigslist. The plastic bodies on those are usually ruined before the motors and switches are, so you can get them cheap. There's one in my backyard now you could have if you lived close. You could scavenge the motor, battery, wheels, and steering from a ride on toy and add a real brushed ESC if you want to have real control over the speed and not just on/off. You'll need a linear actuator for the steering and a BEC to power it and the radio gear. If you really want to fancy it up, you could add a 3DR controller to it and have autonomous capabilities where it navigates a path using GPS.
