Kerbal Space Program

Expected: Rotor uses up to all of its maximum motor output too reach the rpm limit and not more than necessary once the rpm limit is reached.

Actual: Depending on the circumstances:
A Rotor uses maximum power even though it has already reached the rpm limit and should reduce the power.
B Rotor does not use all available power and fails to reach the rpm limit.

To reproduce, launch the craft from the attached craft file and perform the following steps:
1. Open the menus of one of the blades and of the motor.
2. Increase the torque limit of the motor.
3. Observe bug A occur. The rotor reaches the target rpm but still uses 80mu/s. 80mu/s is the limit as the motor size has been set to 5% during construction.
4. Set the deploy angle on the blade to 34°.
5. Observe bug B occur. The rpm decreases but instead of increasing torque to compensate, the motor decreases output below the previously achieved 80mu/s.
