John, The simplest method is to use a pair of 3/8 inch ID CF tubes for the spar. If you are using fiberglass for the skin, a 30 inch spar will give good support. If you are using wood or CF for the skin a 20 inch spar will work. If the wing is a two piece, an aluminum joiner rod 10-12 inches long will work well and will not break. I have one built this way (built by Fred Sage) and it will take a full pedal launch. Check my web site (hilaunch.com) for tube and rod prices.
