Excellent bit of flying Iman. How about a quad-copter? I know my old Bix with an APM1 wouldn't have the navigational accuracy to fly autonomously in your space, even assuming it could get a good gps fix in doors.

Dear Warren

Thanks for reply.

My research is based on both platforms (fixed-wing and Rotary-wing). So my work for quadrotor is finished and some papers are published. I have 1 more year to work on Fault-tolerant Flight Control (FTFC) for fixed-wing and here in Canada, I can not have any experiment till Apri/May due to weather. So I decided to fly indoor. Fortunately there is good signal GPS inside of this dome. My handheld GPS detected 8-12 satellites.

Here is my quadrotor at the same dome:

And some more FTFC scenarios:

Prop brake (intentional) for 70-100% in flight using control allocation and reallocation:

Trajectory Tracking using Model Reference Adaptive Control (MRAC) and Gain Scheduled PID (GS-PID):

Payload Drop using GS-PID and Model Predictive Control (MPC) and their comparison:

How about a GWS Slo-Stick? The wing is large enough to get your gear in the air without too much speed and large control surfaces work well as slow speeds.

Yes, actually that was the first thing I found while searching in the web. That's for sure one of the candidates. Also here I found the modified version (extreme slow flight):
