Flight stabilisation without IR sensors

Posted by Andy Joyce on April 5, 2010 at 10:11am

Has anyone tried flying an Ardupilot without the IR sensors? Assume if you have a very stable platform ie one with sufficient dihedralthat basic navigation should be possible using rudder alone with the elevatorcontrolled by GPS height.

My first UAV plane (a soarstar/wingo) used Ardupilot V1.0 without IR sensors. The deflection of the rudder had to be turned down to almost zero though, otherwise some serious spiral diving occurred threatening to fold the wings on occasion. Some info of that in the first part of this post: here

I did get a few pretty successful autonomous flights with it...

This was how the first version of Ardupilot worked. I think that would be version 1.*. Yes it can and has worked a couple of years ago. Thermo's from FMA Direct were the first major upgrade. Now we're into 6DOF IMU's. Go back to the beginning. Version 1.0 is still here.

some people use it that way,

autostable planes dont need assisted stabilization but without it is always a risk even in stable platforms
