Here is a taxi check of the Robbe Airbull flying wing. Pretty neat little jewel I picked a while back from the swap meet. The kit did not come with a spar and I figured it didn't need it right. Not... So I flew it and all was good until I put some excess loading on the wing and got stuck in the bird flap and it snapped clean in two. Sorry no vid of that, figures. Any way I have since added a carbon fiber arrow shaft and now it is strong as a board. The maiden flight is when the wing had no spar. It did fly great without the spar until I overloaded the airframe. Thanks for watching.
