Inflation bladder works great. The original was done that way too.
7.5% E374 is the original foil. But lots of other popular ones out there. DS4, SD7003, S6062, S6063, RG14, RG15, HD45, MG06, dd928416, Don Ayers foils, etc. James Hammond has a TWF foil too, I think it's called something like JHHS701. I used modified Drela foils on my last wings and they work great. How good is the lift at your local slope?
The standard size wingrod is 5/16" steel pin (8mm carbon rod fits too) and the wing tube is 11/32" K&S brass tube (0.014" wall).

Thanks for your fast and certain information.. i study the inflation bladder, ( and aire in my Favorite list.... ) but, are other technic diferent...? itīs because the inflation bladder represent to me, buy all the equipment, bag, valves. etc, and if can avoid it, better for me, if the only way is the I.B. go for it....
Thanks for the airfoils and the diameter of the tubes, stell and carbon bars, i follow you in other post about the xica and i like your comments of these birds.

Is the dia. too small to use a clevis with a washer on the end of a control wire about 6" long attached to a 1/4" stick as long as necessary. Of course you may have to hold a flash light in your mouth to see what's happening in the mold. It can be done.
