Describe your preferred solution
Re-add the throttle cutoff option as disabled (-1 value)
Describe possible alternatives
Re-create a new parameter to cut the throttle before flare to prevent prop strike for belly landers

"I’m flying an Opterra, 6ft wing. This is a tractor configuration and is a belly lander. I am using q ground control for my ground control station and I have an Ark electronics Pixhawk board with px4 .15 firmware.
I have a pitot Air speed sensor and downward facing lidar for terrain detection. I have it working very well in auto mode and am preparing for my first Auto landing. I am trying to find a way to stop the motor spinning sometime around the flare so when I land on the belly I don’t get a prop strike but I can not find any sort of glide command. "

"Interesting. This used to be easy but throttle cut at alt during landing was removed (during the landing 1.14 refactor).
Ok, there’s obviously still a use case for it. We should leave it to -1 for disable (that used to mean 2/3 of flare alt for throttle cut).
@james_sawyer can you open a git issue. This wouldn’t be too big a deal to put in."
