Title: New Prototypes nearly done
Post by: JoeJust on January 02, 2020, 09:35:22 AM: OK, start laughing, but here are two pictures of the prototype "European Style" profile Carrier ships.The lousy looking covering really isn't that poor, I just reflects the dormant "trumpeter Vines hanging over the table of our gazebo. Questions? The wing is held on and is removeable to try another type.

Paul, not engraved in stone as yet. The whole project is to see if several new ideas an be put to work. I these two prototypes show promise then I will build something like the attachment for entry in a contest if I ever get up enough energy to ever fly competitively again.

Flat bottom airfoils let you fly slow, but make it harder to hang.

Symmetrical airfoils can be stalled-out easier and are thus better able to hang.
