Did you ever find a good way to do this? @Amirabadi

@Huax oh I think i know nothing about PID
but i will try smooth thanks for helping

You can either use smooth or PID.
Both makes your plane less responsive though.
Example would be
smooth(expression,number)
PID(Pitch,-VerticalG+1,1,0,0.5)
but PID requires some tuning

In your case, don’t do anything with the 2nd number corresponding to I, just play around with the 3rd value corresponding to D to make it easier

now it perform dolphin maneuver can test and find its problem
it happened on wasp 1.11

@Huax let test it thanks for helping

So, I tried the codes.
The 1st thing to say is that those signs are weird.
Then it’s /9
Also there is -1 so your planes doesn’t go crazy at level flight.
The price is it could go 10G at the bottom of a loop, if you don’t want this, set it to /8
So it ends up to be
clamp(Pitch+(VerticalG-1)/9,-1,1)

@Huax sorry but not working
can you test it on wasp

@Huax looks simple
Lets test it
Thanks

Pitch-VerticalG/18
should work for 9G as at 9G Full Pitch, the output is 0, so it will not go beyond that point
Change 18 for 15 if you want 7.5G
