3D Multicopter Graupner Alpha300Q Hysteresis
#2
You have switched to the flight condition 3D or 3D Hot? Then you can modify the throttle curve in the setup. There is no specific Hysteresis setup because during my tests I have not noticed any difference to the real model.
Maybe you like to decrease the 'Response Pitch' preset? Or increase the 'Pitch Hardness'?
I use 3D, but the problem is that at zero pitch the throttle goes to zero. So if you are in the air, do a loop, go to mid stick you have zero control because the motors do not spin. This is completely unrealistic since the motors always spin in a 3D quad, so you can do a roll at mid stick.
I tried changing the throttle curve, but how do I change it so I always have some throttle when reversing from pos to negative?
Also, I do not really agree that hysteresis is not important. If I fly normal and go to mid stick I do not want to go negative, nobody can fly that accurate, and the motors would start flip-flopping between pos and negative around mid stick (eg from pos 10% throttle to neg 10% throttle). That is why there should be a dead band with hysteris.
But I would already be happy if I could just figure out how to set the throttle curve so I have no motor stop at zero pitch (without hysteresis). So it goes from +10% immediately to -10%, how do I do this:

Ok, booster works, thank you!
>Please name me a system which has this feature in reality. Then I can take a look.
All the 3D quads I know work with hysteresis. I personally have two (Graupner Alpha300Q with graupner gyro and a betaflight quad I built myself).
Betaflight also has the 'booster' feature, it's called airmode in betaflight. But it cannot work like you did it in the sim in real life. With airmode on, betaflight temporarily augments the throttle if one of the motors would drop below a certain value. So it is a bit like your booster but with a big difference, the motors never stop.
Also, the quad would become unstable if the motors stop because then the gyro+controller cannot do anything anymore. Spinning up a motor from zero takes too long, the gyros+controller make little corrections all the time, even at zero pitch.
