Drag spars.

The Drag spars are being glued into the bottom skins along with the control surface LE spars.
The drag spars were pre made by winding 30mm wide strips of 100gsm glass on plastic covered carbon rod for a mandrel. Then wrapped with more plastic and allowed to cure. The spiral wound plastic pulled out of the cured tube easily.
The LE spar was made using the drinking straw method. The straws were threaded onto a mandrel and taped together. Then they were spiral wound with glass as above. Wet out, slipped off the mandrel and cut to length before gluing into the lower skins.
Drop sheet plastic was placed on top and the top skins and moulds where then clamped onto them for curing.
