Working with RedwingRC, XionRC has sent a check returning my funds. Thank you, Jeff, at RedwingRC.
Jeff has asked if I could help find someone to manufacture about 100 1/4-20 studs and rubber grommets for the wing lock product. Picture, attached. If a serious source makes contact, I may have drawings, soon - they're on a computer, somewhere, but I think Jeff has his hands full with higher priorities.
