<short_desc>Thrust to PWM model parameter</short_desc>
<short_desc>Thrust to motor control signal model parameter</short_desc>
<long_desc>Parameter used to model the relationship between static thrust and motor input PWM. Model is: thrust = (1-factor)*PWM + factor * PWM^2</long_desc>
<long_desc>Parameter used to model the nonlinear relationship between motor control signal (e.g. PWM) and static thrust. The model is: rel_thrust = factor * rel_signal^2 + (1-factor) * rel_signal, where rel_thrust is the normalized thrust between 0 and 1, and rel_signal is the relative motor control signal between 0 and 1.</long_desc>
