Default Skydrill engineering problem...

Per plans the wing is built upside down to maintain a flat top wing (dihedral bottom). So the "jig tabs" are correctly on the top of the ribs. But the slot in R1 for the ply wing mount "tongue" is cut on the wrong side of the cord centerline. It should be on the top side of the cord centerline. It is currently cut on the bottom side of the cord centerline, opposite the "jig tabs". See the R1 rib dwg.

So the Skydrill's that have been built already, either have the wing on upside down (anhedral top) or must have had the fues former cut out. Which I guess I'll have to do(?) I skimmed over some Skydrill threads and didn't see it mentioned. Did I miss something?

Hi EDH... I went and looked at a plan and I see what you may have found. The tab on that one does look like it is on the wrong side doesn't it. Its not the slot that is cut wrong but the tab. There is a tab on the RR rib not far away so I wouldn't worry too much the tab on R1. The airfoil is symmetrical so you could cut it off (tab) and glue it on the other side. Don't cut the former... Not too much meat there as it is.

Wow that's what I call service! Ten minutes and I got an answer from the man himself!

Thanks Skaliwag. Unfortunately I'm pretty well finished with the wing. Ill cut 1/8" out of the former and reinforce it with some ply. I'm kit bashing this one a little. It's going to be electric and I'll probably do a little build thread on it over on RCG. I'm trying to make a "mini-me" version of Bridi's original orange Kaos. I've already shortened and sharpened the nose and trimmed a little off her waist for that sexy sub-fin. Tricycle gear with NWS. Look for the thread next week.
Thanks again...

Can you redo the tongue?

Nope it's installed for good. But maybe I can it dremel it off at the leading edge, cut a slot and add another to the top of the original(?) That might work.

Be a better idea than cutting the former..
