CFTP archetype gurney

[Stan Whitney]

Got around to trying out the archetpe gurney for the cftp wing. Fits the AC wing I have well. 1" gurney, let me lower the wing to the 'street' AoA settting and still handle the same.

I think that's about the best data you're going to get with this. I haven't seen Archetype put anything in a wind tunnel or release any CFD info before.

None to be had, just the real world test. Nine lives has good data on the gurney effects on their 10" and 12" chord wings. 3/4" provides about a 50-70lb bump in Df at 100+, so thats what I figure. My other calculated numbers for this wing line up pretty well with theirs. So about up to 20% , with a bit more drag.

They dont. AJ is the only one with wind tunnel data
