Hello Service Team,

can someone explain to me how I enter exponential in pitch?

I can only enter in one direction, right?

Invert Flight ?

Go in ADVANCED, Setup tab then select Input.

Here you can find all the flight contorl unit exponentials setup. Also for collective Pitch.

Exponential curves are symmetrical with respect to the centre (Pitch=0) so you get the exact same effect in normal and inverted flight.

immagine

When the model is vertical, the curve being symmetrical on both sides with respect to the centre, you get the same effect by giving positive pitch or negative pitch.
When you are in normal flight, however, reducing the pitch will result in a smaller reduction in pitch than when you increase the pitch.
This effect of making the model go down less than it goes up will give a 'floating' feeling to the model that some call 'anti-gravity'.
The exact same effect will occur in inverted flight (the model tends to descend less than it rises by giving commands of the same amplitude but in opposite directions to ascend or descend).

Don't worry, you can land.
In fact, exponentials do not reduce travel but leave full travel. They only change the stick positions in which you hover the model (straight or inverted).
Setups 1, 2, 3 are also for this purpose.
Copy the Setup you are currently using to the other two Setups.
Then set the pitch expo to 5% on Setup 1, 10% on Setup 2 and 15% on Setup 3.
I assume that, per the instructions, you have dedicated a three-position switch on your transmitter to control the three Setups.
In flight, you can change the Setups to see which of the three values works best for your model and your personal taste.
Remember, however, that RC heli flying relies heavily on automatic control of the model, so once you know which value to use, you should always use that value and avoid changing values and curves all the time so that you can develop automatic control of the model's flight.
You did not say how many channels your transmitter has.
If it has enough channels, you can also use a side dial on your transmitter to linearly change the pitch expo value.

The now (Anti Gravity) included to Pitch Expo latest firmware, there is no added info to the hover flag, is it plus or minus exponentials.

As explained in the balloon, negative pitch exponential values (of more than -20%) require more stick travel to lose altitude and less stick travel to gain altitude. This has always generated the feeling of "floating" in the model that some have recently decided to call anti-gravity.
In future software releases we will try to make this clearer in the balloon.
