You can mount a camera by using a very thin piece of ally, or steel, from a buiscit tin. First you need to build an aerodynamic cradle using wood. One that streamlines the camera from the slipstream, while holding it rigid. Mount the camera to the cradle, by drilling a dole through your sheet metal, then knocking the countersunk head of the screw to recess it. Typically 1/4 UNC. then simply tape the sheet metal to the wing using 2" tape (white) orientating the streamlined end of the mount with the direction of the glider. You can either use a remote control to take stills, or leave the movie mode on!! Alternatively a wooden cradle can be made to mount it to the fin of the glider.
