Hi Alan,
Sounds like the cockpit module might be a touch skewed, doesn't need to be
much to throw the wing rigging out.
Easy fix [ done it before] is a shim on the rear face of the seat back, thi
n piece of steel Reduxed on, clamp it up with a straight edge across the wi
dth of the module, so the port spar sits square up to it. Put a couple of C
SK rivets in as well, so it can't get knocked off when rigging and fall int
o the bowels.
This will true out any skew, shim won't need to be much as when the port ti
p moves aft, the stb tip will move fwd the same amount. A 1/2'' large area
washer might even do it ?
This will open the gap between the port lift pin / fuselage, and close the
drag pin gap.
Cheers,
Nev

I am so pleased Dave is flying. I set myself a task,over the Christmas holi
days, of fitting my newly modified (Mod 78) wings on the fuselage for the f
irst time.
Bushes bonded in and cured I moved on swiftly to align the wings only to fi
nd the Port wing seeming to be 1" further forward at the reference point th
an the Starboard wing. This means that the gap for the new front right moun
t will not even take the mount let alone the layups, the rear right gap is
correspondingly too much. The right wing sits really well both bush gaps as
expected.
I have tied the wings forward to ensure no rearwards movement of the spars.
I have had my remote camera in to cross check.
I have a grave fear that my port spar has sagged but cannot work out how.
I suppose a shim on the port spar inner bush front face will cure this, can
any one think of something else, I have rigged and de rigged 4 times with
different helpers.

kit 463 and full of dread.

did the wings bend much at 3 G? Stiffening the spar stubs should help
to give more bend and a slightly softer ride.

The Phoenix has risen from the ashes. Test flight this morning went very we
ll. No issues and no significant changes.
I was able to pull 3.1 Gs. That is quite a bit of pull. This was both in a
wind-up turn and a straight ahead pull. I didn't feel the need to go beyon
d that level. Its quite a dramatic maneuver. Stall characteristics normal.
Trim settings unchanged from pre mod 78.
It took a few days less than 3 months to complete this. Too many hours to f
athom. I hope there are no more such modification to come in the future. An
ything else down the road should seem like a walk in the park compared to t
his.
I still officially like the change of bolts to flush screws on the CS08 bra
ckets. Piece of mind.
Thanks to Neville and Bud for all their invaluable help.
