Update:
I did a speed validation run today followed by a clean stall attempt.
I actually can't get it to break same as rv10flyer stated its a rocking horse ride
and you loose just altitude. I guess I will have to move the cg backwards
to produce a stall break. The controls were at the backward stop.
I will slowly move the c.g. back.

Myron,
You are way too generous doing this year after year with only a little cash
thrown your way for appreciation. The time spent provisioning and setting
this up all takes away from your building.
I for one will be present. I hope we can both add flying RVs to the show
next year.

At some point you will need to test the rear c.g. limit at full gross. I
certainly agree with approaching that slowly to avoid any nasty surprises.
It is likely useful to know how differently the plane handles stall at
forward and aft c.g. limits. I've heard that if one fully explores the c.g.
envelope and checks all the other flight characteristics and airspeeds that
you will use up most or all of the 40 hours.

I have done so stall testing this past month. I saw little difference between
reflex and 0 deg flaps. Dont remember exactly but maybe 2 knots or so. Stall
at about 2500 lb was at low sixties.
You might want to also verify your weight and cg calculations prior to your next
flight.

My experience with birds down low in slow movers agrees with your
conclusions. I used to do a fair amount of ridge running in gliders;
<500' @ 130-150knots. Lot's of birds down there, especially this time
of year during the migration. Years of talking and reading about these
conflicts led to the same two conclusions; birds will fold and go down,
and pulling up to over them is the best way to avoid them.
More specifically, we would often find ourselves coming up in a bird's
sixes and at the same altitude or lower. Lateral deviations with 50'+
of glider wing is sluggish at best. The thing we learned never to do
was to attempt going under the bird, even if it was 10' to 20' above
you. At near treetop altitudes on the ridge, the bird folds and heads
for the tree tops. Absolutely every time. Pulling up was the way to go
and one would usually just manage to see the bird fold and split S
before the nose covered him up. Some learned the hard way and landed
with bloody cockpits.
However, at higher altitudes my experience (and I think the experience
of others) was that birds were likely to do just about anything. In
slow speed gaggles when sharing the air with them, they just played see
and avoid just as we would. If surprised, the same thing. That is,
they would just react with some quick move that seemed right to them at
the moment.
My personal thinking and plan for action at altitude in an airplane is
to quickly react laterally, towards it's tail if possible, and to pull.
Pull unless the bird is above me. In any case, given my aircraft and
skills, I'm going to go wherever I think the bird won't but it will
always be a pull and never a push.

| Subject: | Air seal fabric around prop governor |
I'm having a hard time conceptualizing what happens at the interface of the prop
governor, the air ramp and the air seal fabric. It seams like a big leaky hole
to me. Does anyone have pictures... or wonderfully descriptive words... of
that area?

You pretty much summed it up. Seal it with rtv and seal material as best as you
can. Keep fiberglass cutout snug except for control arm area. Think of cowl movement
locking prop control up. I have everything else tight and no overheating(over
400F for me) at full gross 120 kt climbout on a 100F day.
