nice as always

thanks james & carl! keep in mind these were from last year ... :) I think we've stepped things up quite a bit after fine-tuning our aircraft a bit more.

I'd love to see these runs as seen by the camera used for control.

arashi, working on something like that in the near future.

The thing I like most on this video is the long duration clips. 

Chopping and mixing camera angles to the beat of the music is "edgy" but this shows me what the view the pilot sees.  And for me, FPV is all about the virtual reality of having my consciousness being in the plane flying down the slope through the trees over the water.  Or under and around the Golden Gate Bridge.

Hey,
Great Video and great flight, however I always wondered: Why are you using a flying wing design and not a conventional aircraft design? Would a conventional fuselage not offer the advantage of having increased yaw stability? Because on most of your videos the poorly damped yaw oscillation is cleary visible. Or does the flying wing offer other features which are more advantagous to FPV flight?
Thanks for your answer
phil

any plane weighing 2kg travelling at 150 - 200kph through turbulence is going to get knocked around. look at 99% of the FPV "conventional aircraft designs", they have terrible roll stability or very bad elevator authority and return to level flight by themselves both on roll and on pitch. A wing, for the most part, flies like a dart, which gives the best feeling of flight.

Do you have any plans to counteract that yaw stability issue?? I know that pretty much all flying wings suffer this lack of stability, but perhaps one could come up with a simple solution like an airbrake controlled by a D-controller or passive means?

you call a controlled airbrake simple? :) we are KISS people - one thing goes wrong, it means a long walk. the yawing is not noticeable in flight. plenty of people have tried. nobody has come up with a solution so far that does not make the aircraft more complicated. we've been having a lot of fun with a little bit of yaw while others have built countless of planes and made countless of experiments - and will probably go back to what we fly with eventually :)

:D, okay I see your point, but you see nothing is so good that it cannot be improved by a microcontroller :). However I would be curious if it really would work to improve yaw stability by an Airbrake controlled by a controller.
