MAV video from Swift II wing

[icebear]

Hi,

Some of you have probably seen my thread about small flying wings and I recently finished my first attempt using a Mini Swift flying wing which weighs in at 150 grams (5 oz) and has a wingspan of approx 50 cm (20 inches).

I attached a stripped #16 keychain cam and took some video while flying over some friends house during a nice summer evening recently.

Here is the video which features full auto take-off, flight and landning with the Gluonpilot.

Enjoy the music too from swedish Laleh...!

Wow, spot landing! Your landings are more precise than mine

The video doesn't look too shaky with the small wing.

Thanks Tom!

Considering that I planned the route 5 minutes before going to our friends for dinner, it was quite good...

Actually, the small wing is easier to plan landings for since it flies more slowly and loses altitude more quickly.

I just moved on to the bigger TechOne Popwing (900 mm wingspan) and now I have to re-learn again...

The small wing was stable enough in calm weather but the Popwing is noticably more stable.

Any tuning tips for flying wings are welcome - the Funjet is very responsive so I am guessing the wings need a little more P-term in pitch/roll?

Most flying wings are very responsive. I guess the standard deflection of this wing's ailerons is just less than your funjet's. My 1meter wing is very responsive Adjusting the P-term of roll2aileron should help to overcome this.

You are ringht, Tom (as always ) - this wing has not so much surface deflection as it is setup, so I just might increase that a bit before tuning parameters.

So far I have been able to run the "standard" parameters in three different airframes with good results so I may be a little spoilt!

Please post a picture of your wing - here is the Popwing after today's flight in the woods of Småland...

It is all really custom build
It looks fragile, but it isn't because of the 1mm multiplex I glued to the bottom (which also follows the curvature of the wing)

Thanks for the pics and info!

I just did a new flight with more aggressive throw and the Popwing tracks much better. Still a little trouble to keep altitude so I just need to increase gain and I think it will be perfect !
