I am very pleased to welcome you on this forum!
Wings ection is correct in that you can be sure if you look at this picture /media/kunena/attachments/legacy/images/air.jpg
Air above the wing must have a long way, because of this air flow rate up above than under the wing, and hence the pressure above the wing is also below.

Hi. I know that,to make good wings you need somethig light, like the carbon fiber and the balsa wood. I have finished an airplane, covered with film, all plane is made from balsa wood. The carbon fiber is sufficiently flexible to make the wings from one rod(without cutting). In the case of balsa wood, you need to put in hot water for a few minutes(10-15 min) and let it dry on the desired form(oval). it takes 30 or more minutes. The normal balsa wood will spilt or break.
And pay attention when you bend the wood, don t bend directly in the desired form. Bend easy at start on an easy curved form, and medium curved shape... until you are sure that the wood is ready to bendon that form. It depends by how curbed is the wing.
The covering part: [img]http://http://aces.nmsu.edu/pubs/_circulars/cr-606/images/Figure10.jpg[img] First, you need to build a simple frame, smaller than the frame from the image, and put the plastic film, very good stretched, like a perfect plane surface. After glue the wing frame and put on the stretched plastic film. For this operation, use a paper glue. After the drying of the glue, cut the exces of film. The next operation will be the heating of the film. This thing can be done with an electric heater.[img][/img][img][/img][img]img.diytrade.com/cdimg/526725/3379784/0/.../electric_heater.jpg[img]
Set to the minim power. the heating proces will make the foil more thight. Attention! Too much heat can destroy the foil or detach it.
the same work can be done to the tail. Good work and happy holidays!
