|Ball MOI RatioRatio of MOI to mass times radius squared.
2/5 for a solid sphere, 2/3 for a hollow sphere, 1/2 for a solid cylinder, 1 for a hollow cylinder.
|Ball StiffnessStiffness of the ball. This should be evaluated as a shock condition and near the amount of compression in the case of nonlinear balls (which, practically any ball will be)||+/-|
|Hood StartAngle that the hood starts at, with respect to vertical.
A larger value would mean the hood wraps around more.
|Hood EndAngle that the hood ends at, with respect to vertical.
This would be the same as the release/departure angle with respect to the horizontal.
A larger value would mean that the hood wraps around less, and creates a more vertical shot.

|# MotorsHow many motors do you have in total for this mechanism (assuming they're identical, and geared together)|
|EfficiencyEfficiency of the transmission|
You could find this empirically using this tool by guessing values until the idle current matches your shooter.
|Free SpeedThe maximum RPM of the motor||[RPM]|
|Stall TorqueThe maximum torque of the motor, occurring at 0 RPM||[N-m]|
