fw_iterm_limit_stick_position - possible improvement

[0crap]

Current Behavior

After a roll in ACRO mode, with an airplane, the bounce back is horrible.

Desired Behavior

After a roll in ACRO, when the stick is returned to center, the plane should stop rotating and not bounce back.
(In MANUAL mode there is no bounce back observed.)

Suggested Solution

Add to "fw_iterm_limit_stick_position" the possibility to include zeroing out iterm. (Reset and keep it at zero.)

Who does this impact? Who is this for?

Advanced airplane pilots who like to do acrobatic flight in ACRO mode.

Additional context

The blackbox log from my ATOMRC Dolphin, on iNav 5.0, clearly shows iterm is responsible for the bounce back after a roll.
The blackbox log also shows, when a roll is done in MANUAL mode, there is no bounce back at all. (iterm is always zero!)

ACRO:

MANUAL MODE:

Lowering the parameter set fw_iterm_limit_stick_position does help, but does not solve the issue because iterm is not set to zero.
(The default of 0.500 is also way too high in my opinion.)

This could very well be solved by #9905 👍
