Many people ask us about these settings and so we will explain them here: 

Stop gain

During a tail stop it will be helpful to use a bit more tail gain to get a crispy stop. This adjustment can be done for both sides independently.

1 - Side A:
CW rotating main rotor: Stop gain for stops from CW piros (TX stick will be moved from right to center)
CCW rotating main rotor: Stop gain for stops from CCW piros (TX stick will be moved from left to center)

2 - Side B:
CW rotating main rotor: Stop gain for stops from CCW piros (TX stick will be moved from left to center)
CCW rotating main rotor: Stop gain for stops from CW piros (TX stick will be moved from right to center)

Tail optimizer

When you give any kind of tail stick input we will have a better overall response if the system knows how much throw should be approximately set for the rate you want to achieve. This will be much faster than the control loop can do. This has also effects for a negative acceleration (deceleration)—especially a tail stop.

The optimizer will estimate the used throw to get a good stop automaticlly in flight. Therfore turn it on, do a flight with some piros left/right, and with stops.

If you will get a high value as result (80 or more) and a weak stop behaviour, there will be some work to do on the tail now. Possible reasons for high values can be too little headspeed, to short tail blades, too little tail throw—or even too much tail throw (this will cause a stall effect at the stop). Try less or more throw as a first thing, bankswitch can be used here because tail throw can be set individually each bank ;-)
