Gentlemen!
We do have Peter's most excellent material list, with all the "bits & pieces" --
I have "assembled" the spar from these pieces on paper some time ago -- Moment
of Inertia for the front PFA spar is very close to the routed "I" spar (1"
x 4 3/4" with the 1/2" web thickness). It's really a good design that only needs
a wider opening for the front spar in the Piet wing ribs (1 1/8" vs 1") --
The rear spar only needs the original 1" spar opening.
I could use some hints on the "swallow-tail" blocks between the caps! ;-)
Cheers!
