Better ask one of the Kings of
Aviation.

They are busy with someone that is wondering why he has not been allowed to solo after five hours.

Someone should tell him that no one could
possibly care about the slope of his learning
curve for his first 10 hours.

The slope of his learning curve for the last
10,000 hours of flight time is more interesting. 

If he can maintain a near-vertical slope for
10,000 hours, that would be interesting.

For 5 hours, not so much.

PS  I soloed in 4 hours on a Maule M4-210C
(included spin training on buck fifty) but no
one gives a shit.

The point I decided not to make over there is. Regardless how natural you are and how few hours you fly dual before going solo. You have no idea what you don't know at that point.

Sure it's cool to brag, "I soloed after nine minutes of dual." But it's really pointless. Kind of like "I have 45 000. Hours sitting in a cockpit while auto flew the planes."

Golly Wally, that's neato.

I doubt anyone on AvCan knows the difference.

Easy now, GoBoy is over there, he likes nice old fashioned flying machines.

Granted he probably is not ripping fabric that needs to be temporarily repaired because there's another show in an hour. Still, I bet he knows his tube and fabric.

GoBoy (whom is over here now too) is the real deal.

He has a gorgeous Fleet Finch that looks like it just
came out of restoration.  An airplane like that isn't
about to tolerate a pilot who doesn't have a clue.

A few years back, we flew at an airshow together.
I forget where - Orillia? - but there was a line of
tall trees on the west side of a north/south runway
and plenty of wind blowing.  PDW would have creamed
his pants over the windshear.

It blew a Canso over the flight line!  It was plenty
of fun in the Pitts, with it's high wing loading.  It
was so windy, that huge WWII taildragger - forget
it's name, Lysander? - couldn't even taxi, let alone
fly.  And Rick Volker - fantastic stick - flew the priceless
bf109 out of Muskoka to try to get less crosswind
with that finicky landing gear.

All this to set the stage for GoBoy, risking his
beautiful Fleet Finch in very strong, gusty crosswinds
that would have grounded the military back in WWII,
and he made it look easy.

See, he can both maintain and fly some neat stuff.
Not many people left, like that.  All we have today
are kids in white shirts that push buttons and think
they fly airplanes.

It's coming back to me now.  The weather briefing -
which should have mentioned the wind - instead
focused on mesoscale activity - I don't even know
what that means - over Kansas.  And NavCan refused
to issue a NOTAM for the airspace - they hid it under
federal airspace or something, you needed a PhD in
useless government bullshit to find it.

Oh yeah, and I think Bobby and I mooned Carol Pilon.

So back in high school auto body class a guy brings in his Ventura in with a nice bright yellow paint job for a wash. The instructor says, "Somebody painted it with a brush." We all turn to him and say, "What?" He says, "Look at the brush marks." And points out brush marks. It was the best brush paint job I have ever seen. I have seen plenty of proper equipment sprayed cars that were horribly botched.

Yeah I told him I was lonely over here. He fed me beers at OSH. His buddies down there are awesome too. One made me stop using the word "dude" the way I used to by asking if I knew the origins.

I don't know the cause but I have seen way too many cars with orange peel even from shops paid to do the job.

Actually, you want to see brush marks in the
paint, with fabric.

You want to use a brush to work the nitrate
in.  If you don't do that, the paint won't stick.

Aviat did a horrible experiment back in the 90's
where they tried spraying on the nitrate to get
rid of the brush marks.  All the paint peeled off.

Here's an expert.  He doesn't know as much as
an AvCan moderator, but:

[quote]Nitrate dope is applied as the first coat on all polyester fabric.  Even though nitrate dope is very flammable, it must be used initially.  Butyrate dope simply will not adhere to polyester fabric.  Otherwise it would be used as the first coat.  So, apply nitrate dope first and then all remaining coats will be butyrate to reduce the flammability issue.

The first coat of nitrate dope must bond to the fabric or all layers are in jeopardy of peeling.  I am sure many of you have witnessed first hand the peeling off of fabric coatings.  This is a common problem area and comprises one major reason that aircraft must be prematurely recovered.  If the first coat does not bond to the fabric you can literally peel it off along with all subsequent coats.  I have seen aircraft that you could take an air gun and blow the coatings off of the fabric in sheets. 

[b][u]I recommend brushing the first coat of dope onto the fabric. [/u][/b]

Care must be taken to ensure proper penetration of the nitrate dope through the fabric.  This is why I recommend brushing on the first coat.  You must penetrate the fabric with the liquid to get it to the backside or the underneath side of the surface.[/quote]

Aviat tried spraying the primer.  All the paint
peeled off.  It was horrible.
