ESC/Motors for a custom designed 1/5 scale project
I'm working with a team at my university to design a 1/5 scale off-road vehicle for a specialized purpose which I cannot disclose here.
We're using a chassis taken from this car:
As you can see, this is a 4-wheel drive vehicle.
We stripped out the stock motor and ESC, along with the driveshaft to make room for specialized electronic equipment that the vehicle will be carrying.
We are now designing our own drive-train for the car, and want to use 2 brushless motors, powered by a 4S LiPo (14.8V) setup.
That is, the car will remain 4wd, but will be powered by a front and rear motor.
Here's the big question:
What ESC and motor setup should we use?
I'm asking here because I'm sure there are RC enthusiasts with greater knowledge in this area than any of us on the team have.
Here are the requirements based on the design:
The ESC should be sensored and must support 4S LiPo power.
The brushless motors (x2) need to provide high torque rather than high speed (i.e. higher turns / lower kv): This is because the vehicle will be quite a bit heavier than stock and is not going to be driven at "bashing" speeds. Rather, it needs to have very good low speed control.
So, what do you guys think?
It sounds like your making some sort of FPV or robotic arm crawler. I would take a look at this. It will let you set up and run 2 ESC's off a controller.
