I am working on a robot with focus on speed. At the moment I am looking for a suitable motor but it would help if I understood the difference between the various options.
To provide some background, I have not worked with RC model components before, but I think this is the only place for me to find the components needed for my robot, such as the motor.
I have already figured out how much power the motor needs to accelerate my robot as desired, taking energy conversion efficiency and tractional resistance into account. It's about 170 watts, depending on the final weight.
To limit my search further, I need to decide on either using a RC car motor or a RC helicopter motor now, but I don't understand the difference between these options.
Focussing on brushless motors (if that matters), what are the differences between RC car and RC helicopter motors? What needs to be taken into account when choosing between them?
