Around 95 cm span and 14 cm chord.
It's styrofoam so weight would be around 100 gms for the wing with the tape. Add some more for the spar.

Yes we are getting very nice finish if we are using hot wire cutting , but i hand carved the wing
Anybody have some idea about the technical detail of the wing profile and performance of the skysurfer wings because i copy it in my piper cub wing.
