Steve, the copper buss bar comes with Van's wiring kit. You could
probably find stainless sheet at Aircraft Spruce. A lot of times we find
stuff like that at Home Depot or Lowe's.
Leland in Pleasanton
Going to place an order for the FWF this morning
"PS What sort of place does one buy stainless sheet? Also, while I am
thinking about it, copper bar to connect the contactor
to the solenoid? No
one got any copper in their FWF kit did they? This is
the kit that supplies
'everything' to finish it off!"

Actually I think thier is copper bar in the FWF kit. Thw FWF includes a
wiring harness which includes the copper bar, I think. I'll check today when I'm
at the shop and let you know.
You can get stainless sheet from A/C Spruce. Current catologue, page 67.
You fellows could just solve this problem by just building a tail dragger.

The plans say to cut a 2 1/4 inch hole in the little wingtip rib adjacent to
the tip of the aileron.
What is this for?

Leland / Dennis - thanks. That makes sense. I ordered the basic electrical
kit wayback before the FWF kit was created, so when I ordered FWF I deleted
the electric kit. I expect the copper is on the spare parts list.

Yep, my elevators are just out of trail down also in cruise. If I had the choice
again I would raise the rear of the wing just a touch as I had to press down
the rear spar quite a bit to get the desired incidence per the plans. If I had
left it at the neutral point that the wings wanted to have I suspect I would
be in trail at cruise.

You could soften up the wing incedence a little by raising your rear spars
and drilling out the hole to a bigger bolt size, but on the other hand the
trade off would be more up elevator needed for slow flight and landing. Maybe Vans
decided it would be better to have more trim drag in cruse and less nose down
pitching in slow flight. Wont know for sure unless somebody tries it.

Why not adjust the horizontal stabilizer for neutral trail of elevators?

That might be safer, wouldn't be changing the wing angle of attack in
relation to the thrust line of the engine that way, and also easier to put back
where
it was if it produced undesirable results. Maybe just stick a washer under
the HS forward spar where it bolts to the fuse longerons?

Seems to me a big point in all this is: At what loading and load distribution
are you talking about? Solo with no baggage and full fuel is quite different
from two fat boys, and a cooler of beer in the back. And, does trim drag cost
as much performance as extra baggage?
Changing the horizontal stab incidence would be pretty easy, if it didn't screw
up the tail fairing fit.
On a previous subject, the hole in the wingtip rib is a lightening hole, according
to Van's. Also for letting birds and insects inside the tip.

Staying within the cg limits of the airfoil is a pretty narrow little teeter
totter, keeping in mind this is a low wing where we are sitting on top of the
triangle rather than below it as with the high wings. Were splitting hairs
here but a really small change to the HS should wind up being equal to fat boy
passenger drinking all the baggage, then ejecting it plus his lunch forward
about to the CG moment of the rudder pedals, This of course is assuming he had
one
of those Great falls 10th ave Big Boy greasy gut bombs for lunch with approx.
weight of 2.5 pounds, give or take a chunk.
