Power is a measure of the electrical current being supplied to the motors. If you set your Helix on the table with the motors on, you can turn the tilt motor and feel the amount of force it takes to move it from one magnet to another (this is called “slipping poles.” Lower power makes it easier to go from one magnet to another. Higher power makes it harder.
Slipping poles while operating the Helix can cause problems with stability. If this happens, you should increase your power settings.
Higher power usually means better performance for erratic or harsh (e.g. windy) conditions or when you are being more aggressive in your moves with the Helix. If you have added accessories (especially a large monitor), you will likely need to increase your power a bit. Higher power also causes the motors will heat up more. Normal power settings range from 100 to 210, depending on the size of the camera and the axis in question (assuming no encoder use). The pan axis uses more power than the other two motors. Heavier cameras, of course, tend to require more power. Always check your motors and control board for heat when tuning and lower the ‘Power’ value if necessary.
Low Power will result in the Helix being pushed into position by wind or other weak forces with not enough power to recover
High Power can result in motor heating, aggressive oscillation and controller failure (in extreme cases)
