RC car Motor help

[ironasona]

I was told to make a RC car that can go vertically up a 180 degree angle tube , 2m , and i wanted to ask what type of motor would i need to be able to do that ,car weight is 600grams. or is there a calculation for that .ty )

What's a 180 degree angle tube?  My grandson has a couple of toy cars, they are remote controlled cheapies, they'll drive up a flat vertical surface (which is what 180 degree angle means to me) , they'll even drive across a flat ceiling.

sorry i meant to say a RC car that can climb a vertical tube in a 0.145m diameter tube

How fast?

The motor and gearbox, just needs to provide a force of f = mg, on the outside of the tyres, where m is the mass in kg, 0.6kg in this case, and g is the gravitaional acceleration of the earth: typically 9.8N, giving 0.6*9.8 = 5.88N.

Suppose the car needs to travel at 2m/s. P = f*s = 5.88*2 = 11.76W.

In reality there will be losses, so the motor and any electronics driving it, will need to be rated to much more power.

As I mentioned, my grandson has a couple of toy cars, that are capable of driving up a flat vertical surface, or even across the ceiling - they're powered by two AA cells, I don't see AA cells lasting very long powering an 11.76W load.

The challenge as I see it, is maintaining sufficient traction - the car can't climb the wall unless it has sufficient traction - my grandson's toy does it through what can be considered a "reverse hovercraft" principle - a thin flexible rubber skirt just long enough to bridge the gap between the chassis of the car and whatever flat surface it's on, and a fan to create a vacuum to pull the car against the surface.

The weight of the vehicle is obviously going to be a critical factor.

Is RC Remote Controlled or Radio Controlled?  My grandson's toys are radio controlled, so self contained, but you can do remote controlled using a wired controller which would enable you to put the power source in the controller, thus reducing the weight.
