Nice plane!
Thanks for the pics this helps some.
So does that telescoping bar stay attached to the cabin front frame all the time?
What is the aluminum sheet labeled "door gusset" ?
I agree that it seems too cumbersome for common use, but that is not why I'm interested
in it. People have commented about how ugly is is and I could not figure
out what they were talking about. But if that bar stays in place maybe thats
what they are referring to?

This is the entry from my the manual I wrote:
Warning: If operating the aircraft at a weight over the gross weight:
1) The load factor will decrease as follows: 1100
g
over gross = 6 x ------------------
Weight in lbs. (1100 +excess)
(for example at 1150lbs the limit load factor will be 3.8
Ultimate load factor = limit load factor divided by the standard aircraft
safety factor of 1.5)
2) Reduced performance:
-Stall speed will be higher.
-Rate of climb and
controllability will deteriorate.
3) The center of gravity must always stay within the design limits.

Let me try that again -- hopefully this is more readable!

Kevin,
Yes that telescoping piece is attached to the cabin frame all the time even with
the wings open.
That was the main drawback for me, it sticks out of the door gusset along the bottom
of the wing causing drag and is very visable.
You could make some fairings to hide them.
With the wings folded the?root of the wings hang from this piece which attaches
to the top of the cabin frame with 2 tabs(rivets).
It would be better to weld these tabs to the cabin frame. Mine did not line up
very well(see pics).
The door gusset is a pain to install without this?option, it would be more challenging
with that tube there. They give you the aluminum
to close up the larger hole you will have to make in the door gusset to get it
to look good.
The tabs or brackets that attach the telescoping piece to the wings will rivet
to the lower spar cap. With the wings folded their full wieght(almost,tips are
on cradle)
is on these tabs sideways and the not so very robust lower cap. If you are moving
the aircraft alot the cap will take some unusual stresses that
could cause cracks. Of course, just folding the wings and storing the aircraft
should not be a problem.
If the telescoping bar could be installed somehow that it could be removed when
he wings are bolted in place(unscrewed at both tabs and slid out the side) and
the brackets
removed from the wings(using bolts and nutplates) ugly looks would go away. If
you made one hole extra large on one door gusset?then the telescoping piece could
slide out from one side, and then access panels made to cover up these holes.
Anyway if you can get this mod from the person on the list for shipping, then go
for it. I was just not motivated enough to go off on another
tangent away from the goal of getting this thing in the air, which I still have
not reached yet. The option is expensive and I traded it in for aux tanks.
Still building and getting close, a recent divorce has slowed building to a crawl,
but I'm very happy I got my plane out of it intact.
Just have to do control cables, access panel for oil in cowl, final inspection,
first flight.
I will update the site soon, it's stuck at Mar 2008 when I moved it to the airport.
Keep sighning the guestbook!

Thanks for the input, that is really what I needed. I think I'll pass on the folding
wing. I really don't plan on trailering it much anyway., just seemed like
a good idea. Well I guess I'm set to start making wings then.
Thanks again!
