Minimum throttle setting - how to set it below 25%?

[chrispyfur]

Hi all.

Just a quick one. Is there a way of perhaps CLI setting the minimum throttle to hover to something lower?

My vehicle will be getting some assistance staying in the air from a friendly balloon. 

Thanks!

I don';t get it?, cant you just either drop your motors to idle (the speed they spin up when armed) or just set them to not spin up atall when armed?

wouldn';t that solve the issue?

I would be very careful attaching anything to a quad like a balloon , it might act like a sail, i tried using a quad to release a glider  it took it up no problem but when released the line got tangled up in the props.

why didn';t you have the release end on the quad and a reversed hook on the glider?

that way the quad gets clear the moment the release happens and the glider drops the tow as soon as it gains enough forward momentum. :huh

Because we are stupid, next question. ::)

It';s a custom built frame, the "quad" is 1m long and 60cm wide and the two large balloons will sit in the center. See pic.

I';ve not flown this yet, am awaiting motors and I';ll be getting it working without the balloons first.

I expect the wind to be an issue but I';ve built quads that could loiter in 60mph winds (it was at 45 degrees but stable) so I';m sure a little correction for drift isn';t beyond the APM. It';s a fair weather ship though for sure.

When setting up the APM I saw that variable and assumed it meant the throttle wouldn';t drop below that %.

If thats not the case and It will spin them down to arm speed if it senses it';s loitering at a fixed altitude without much motor thrust then it';s fine.

But what is that parameter used for if not a minimum throttle?

Sorry, bit of a noob here, this is all an experiment to try and find an open source flight controller that can handle a hybrid airship...

just needed to click on laptop to view full image.
Looks like an interesting project. Keep us updated on your build.

Thanks ms for the interest so far, does a home have an answer to my query regarding the minimum throttle parameter?
