Fred, I haven't measured the ROC yet, but will try this week. So far, things
actually appear not to have changed much. The aircraft does seem to ride
with the tail a bit higher, so I think the tips are doing something, but
without realtively careful measurements, it may be hard to tell.
The weight increased by 9 pounds for the two tips. They're not as light as I
would have hoped, but they do tend to decrease the bending momemt on the
spar in flight. (How's that for a rationalization?)
The biggest change I've noticed so far is a reduced tendency to roll in
turbulence. There is also a slight decrease in the rate of roll, but I
expected that. No adverse handling qualities, and IMHO, the proportions of
the plane look better.
Now, just so I don't run the tip into the hangar wall....
Bill

Yeah, I think there ae enough screws! I followed a suggestion I got form Calbie
that the screws be on 1 1/2" centers. This works out to about 50 screws per tip,
so if that won't do it, nothing will.
There is no spar extension in the tips, they simply screw onto the tip rib. I did
make sure that one screw (top and bottom) went through the spar cap, but that's
all.
Thanks for the compliment. I'm rathr pleased with them myself.

Forgot to ask...... Are you sure you used enough screws to hold them on?
And, did you utilize the old stub spar to attach to any type of internal spar/shearweb?
The pictures looked great.

Ron, if you've been following some of my other replies, the tips were built
from styrofoam cores, using Aeropoxy epoxy resin. The basic technic is the same
as used on the Rutan designed wings for the -Eze's, Quickies, etc. There was
a Long-Eze builder a couple of hangars away who still had his hot wire setup,
so this was why the method was chosen.
I've attached a couple of photos of the work in progress showing the cores
and also a top view of the installation. Sorry about the large file sizes. I hadn't
planned on e-mailing these photos.

Hi Bill,
They do look good.
Have you compared performance before and after at high altitudes? It seems that
ought to be where the longer span would help you.
