retractable landing gear

Posted by renaud barbier on May 21, 2013 at 8:04am

hi,

could not find on the documentation or forum some automated landing gear experience.

 

is it possible to have it controlled by APM2.5 maybe when we trigger landing function or return to home or any other good idea? this combined with sonar should work I guess...

 

any good idea or experience to share?

 

my ultimate wish is that as soon as the multicoper exceeds 50cm altitude it retracts the landing gear and do the opposite while it is coming back to that low altitude.

    I was looking to do this very same thing for a project I am working on. Has anyone made progress on this? I am still very new to programming the Ardupilot.

    Patience Renaud. ;)

    Retracts? I have seen only one old example of this and it was a 2008 or so video of someone who added aircraft electric retracts to their quad, operating by a typical channel switch on the TX. There are several recent examples of this being done.

    APM software, at this time, does not support retracts but I suppose some extra circuitry could be added to perform the function you desire. Is it a necessary feature? For most applications, no.

    If most of the flying would be like a fixed wing aircraft, there might be merit in reducing the frontal area to reduce drag. Is the benefit worth the extra weight and complexity?

    Only you can answer that.
