These holes are used to clamp the door halves together while they cure.
I never found a spot in the plans were it said to rivet them, but I filled the
holes after the doors where completed.

| Subject: | Rear Wing Spar question |
Thanks to Carl, Fred, and Pascal for getting me by my brain fart this
weekend. Using the pneumatic squeezer and dimpling worked just fine.
Thanks,
Bob

Bob;
It's been about year and half and I looked over that section again. I
think I did get out my big squeezer and dimpled that line on top the
1007 a. As I remember, the skins would have fit better if they were
countersinked, as long as you had adequate metal there. My wings are out
at the hanger so I couldn't look at them. Maybe someone else has some
more recent recollections.

OK, I'll bite, what is it about the Grove brake cyls that make them an
upgrade? (I can't stand knowing there's a mod/upgrade I haven't considered )
The whole shebang took 12 hours. of that 1 1/2 was removing center
console and associated electronics.
It took another 1 1/2 hours to remove the old rudder pedals.
fitting the tunnel cover and cutting the slots (took me 3 times) and re
routing the Scat tubes took 3 hours.
Installing the new pedal assembly and connecting the rudder cables took
2 hours.
Remounting the brake cylinders took 4 hours
I figure this should be about worst case:
a. I'm slow
b. It was/is 110-112 degrees
c. my panel is 2 inches lower than stock further restricting access
d. I'm fat (but working on it)
e. I'm old (working on it as well but haven't made much progress)
If these were being installed during the build vs a retrofit, without
the instrument panel or upper fwd fuse in place, it should take no more
than 2-3 hours total. Given that they come fully assembled, that would
actually be a time savings over the stock pedals.

N291RV had its first, second and third flights today! WOW! Great plane! What
a beast! Handles almost hands free. At hi cruise, it needs a little left
rudder to center the ball.
Total time 1.75 hours!
All went well with only a few minor problems to work through. Idle EGT on #6
cylinder was high and was found to be an out-of-round intake pipe causing an
air intake leak Late in first flight, the #2 CHT suddenly went high and was
later traced to the CHT probe.
The plan is to continue tomorrow.

The Groves had/have improved machining, HD O-rings and could sustain
higher pressure creation. They might have had a slightly larger
capacity. They were black anodized - not gold (Kool). They remain the
choice of Lancair builders who are upgrading performance(but that is not
enough after Matco's are installed). They have a Helper spring on the
outside of the shaft to assist to a Return to No Brake mode.
I have suggested to Paul that a 1/8 Elbow fitting added at the firewall
would assist Retro Builders to redirect Scat tubing away from his
fulcrum arms. He is considering that.
The DHI lines are a Big Deal. There have been lots of upgrades from
Nylaflow lines.
Lancairs come across the fence 50% faster than a VANS (in flare) and
more than 60% heavier (with WOW). That all works into the math
calculation for rotor mass, pad surface area and pressure of H-5606.
When the brakes get mushy and the field is short, the operators look to
improved performance. Lancairs need hard surface and 4,000+. Tim
wanted Dirt or Grass and 2500 feet. When there is a cliff, trees or a
dogleg, the improved braking becomes a bigger deal than just HP.
Tim went with dual calipers and 75% more rotor mass (I think 0.435"
rather than 0.250"). I have a firm back east, that grooves my rotors on
the BMWs. The groove is set to minimum caliper width so it is also an
indicator line for rotor replacement. It allows outgassing from the
heated pads to dissipate and return to conversion of energy mass into
friction and heat. It is the heat dissipation that is the science.
Hoyt Fleming put NACAs ducts on the side of his wheel pants and cooling
ducts internally like on NASCAR vehicles to direct the flow over the
rotors. I told John Jessen it is the heat buildup that caused NASCAR to
go to a cool down lap to avoid warping of the rotors from uneven
cooling. Seems the pads were retaining heat and contributing to rotor
warp. It is much like the respect pilots should have for turbo oil and
a cooling cycle before shutdown. Short taxis should be avoided on hot
days. Land long, taxi back, save rotors and $$$.
