after a lot of research, programming, setting and tuning, I'm proud to announce that my Proxima II went in flight.
It was already, but without any autopilot, only to set the right controls, trims, CG and wings angle of attack.
Now it is fully autonomous. This is the more complex autopilot equipped plane I ever build.
Here you can see the plane in full action.
In this video there is a demonstration of the controls possibilities.
The pilot has the following controls over the plane :
- ailerons, differential !
- flaps, with those functions : thermal flaps, crow flaps
- autopilot mode
- coming next will be camera pan / tilt and camera mode controls
Possibilities are :
- roll control over two (ailerons) or four surfaces (ailerons and flaps)
- camber control over four surfaces (I could program it over two surfaces too, but actually I don't need it)
- crow flaps, with roll control over two or four surfaces
- fine trimming of both ailerons and flaps for roll or camber
About the plane :
And finally an amazing board that allowed me to have all those functions mixed with the autopilot.
This mixer is incredibly flexible in programming.
It is fed with PPM stream from RC rx. The UDB is daisy chained to it and feeds back to it again ailerons control for stabilization and autonomous flight.
Here are the schematics of all the connections :
Here you can watch some more pictures of the plane.
Next plans are to mount a video system and use it as an FPV platform, for long time flying using thermals.
This plane is dedicated to Bill Premerlani, as a tribute to him for starting this amazing adventure, for all the improvements he achieved and for letting me the privilege to travel a short distance on this long road with him.
Thank you Bill !
