I would not lift the wings from any point- the actual center of lift is
probably about the middle or so on both chord and span, but it is difficult
to figure that exactly- the reason to install the sings is to pre-twist the
CS spar, not to flex it, which I would guess it would hardly do anyway, so
in my opinion, it would be best to just install the wings and let them hang.

Subject: REFLECTOR:Strakes
I was wondering if those who have gone before me might review my setup and
comment before I glass in my first lower strake. Started the strakes
yesterday. Put the wings on, supported AC by the wing tips, leveled
longitudinal and lateral axis, rechecked canard incidence and adjusted wing
incidence, trimmed and fit the lower left strake. Ready to glass the lower
stake in place this afternoon, but first I am rechecking my setup to make
certain everything is set right. My setup is as follows:
The wings are being supported 12" inboard of the tips.
The landing gear is not carrying any load.
The forward end of the fuselage is being supported under the canard
bulkhead.
The canard is level in the lateral axis.
The canard incidence angle is 0.
The Center Section Spar is level in the lateral axis.
The main wing incidence is 0, set by foam blocks between the wing and
support structure near the tips.
The main wing incidence is being measured:
Leading Edge - measurement point 1" outboard of the strake main wing
junction.
Trailing edge - measurement point 125" inboard of the wing tip.
Please let me know if this setup sounds right.
Thanks,
Joe
