Autohover is directly dependent of rotor Rpm as it is coded now, only "not directly" linked to fuel lever position (from a coder point of view)
If rotor Rpm goes below the normal regulated Rpm, the auhover is disconnected
As soon as the fuel lever is not full forward, the rotor Rpm will decrease and go lower than the regulated value, so the autohover will disconnect
Before the main red alarm lamp was switched off a bit before full forward position, it's been corrected now.
There is no "button" as some may have written, the sound is the sound of the lever reaching its max position.
and same when in full backward position
I did my best to try to explain hope it means Something.
