Re: "Pitching Machine" motors

Oh, check out this post that has a spreadsheet to calculate velocities, angles, etc. and try reading this thread that has stuff with torque, speed, and motors in it that address the questions on the OP.

Yes, but that results in less ball energy at the same launch speed. There's the extra friction given by the cowling and the lack of energy from a second wheel. If you're aiming to hit a goal from a distance with any accuracy, you'll need to have more energy in your system to hit from ~20' or more than a single CIM or similar motor can supply.

Also, this.
