About your 3d printed plane, what are the main features? or some photo?

Thank you
The image is too small to read any values, do you have a higher resolution one?

There's a thread about the plane here with description and a few photos of the airframe: http://3dprintboard.com/showthread.php?2693-Fully-printed-UAV-FPV-plane

I was asking about the wings because that's the heaviest part of the plane in my design, they weight almost as much as the rest of the airframe combined... which is not so good.
Going from memory the wings are around 190 grams in weight and the fuselage plus tail is 200 grams; that's for a 98cm wing with a chord of 15cm, that adds up to around 14 dm^2 so on average the wings weight 14 grams per square decimeter. That's with a 0.4mm thickness, I think at 0.3mm they would still be strong enough and of course save 25% weight.
