Forgot what mag I saw them in mabey 3D flyer but the designer of SFG's I think there called, is working on 3D plane totally Symetrical and with the SFG's.

Due to the added hight of sfg's and Tail put retracks in the wing, thin wire and small wheels. I think he is a aero engineer.

Mabey similar planes will be marketed, closest one with the concept now is the Tensor 4D foamy, no retracts though.

Of course weight would be a concern.
