* At 1500 on the throttle channel, the PIDs will begin to be dampened.
* At 3/4 throttle (1750), PIDs are reduced by approximately 25% (half way between 1500 and 2000 the dampening will be 50% of the total TPA value of 50% in this example)
* At full throttle (2000) the full amount of dampening set in TPA is applied. (50% reduction in this example)
* TPA can lead into increase of rotation rate when more throttle applied. You can get faster flips and rolls when more throttle applied due to coupling of PID's and rates. Only PID controllers 1 and 2 are using linear TPA implementation, where no rotation rates are affected when TPA is being used.

In Angle mode, this controller uses the LEVEL "P" PID setting to decide how strong the auto-level correction should
be. Note that the default value for P_Level is 90. This is more than likely too high of a value for most, and will cause the model to be very unstable in Angle Mode, and could result in loss of control. It is recommended to change this value to 20 before using PID Controller 1 in Angle Mode.
In Horizon mode, this controller uses the LEVEL "I" PID setting to decide how much auto-level correction should be
applied. The default Cleanflight setting for "I" will result in virtually no auto-leveling being applied, so that will
need to be increased in order to perform like PID controller 0.
The LEVEL "D" setting is not used by this controller.
In Horizon mode, this controller uses the LEVEL "I" PID setting to decide how much auto-level correction should be applied. Level "I" term: Strength of horizon auto-level. value of 0.030 in the configurator equals to 3.0 for Level P. Level "D" term: Strength of horizon transition. 0 is more stick travel on level and 255 is more rate mode what means very narrow angle of leveling.
