Hi Buz,
I chose to register my aircraft with our authority CASA (your FAA),
being GA Experimental. Our flight test program looks very
comprehensive, some 51 pages, with a 40 hr.fly off. I would expect it
would be pretty much the same as yours. CASA here, with all the other
regulations, does seem to just copy yours to a "T"
The other authority here is the RAA, (Recreational Aviation Australia),
I don't know much about it, but most people seem to go this route. I
believe one does not need a medical certificate and maybe there is a
restriction on entering controlled airspace.
I'm sure Dennis could chime in here, there must be many advantages.

Jim,
I actually am currently using a white tape on the wing root that
is a very close color match. I have a roll that I bought from a sail
plane supply place on the inter net, but have found similar 3M tape at
the home supply stores. Those stores also have a white electrician's
tape that is easy to use.
The wide clear tape that I used to use (it does not seem to go
around corners as well as the white stuff) was found at a school supply
store and is used for binding books.
As to the very wide (about 4.5 inches) Mylar that Brain and Earl
mentioned for the flap and aileron gap seals, that was also found on the
net, but was too thin (.01) for the intended use. The best solution for
the flap gaps is the one that Pete Disher has come up with. See one of
the past newsletters for photos. He will be flying soon and I feel
certain he will share his performance data with our group when he
finishes his 40 hour test phase. (By the way, Australia, what are the
test requirements "down under"?

A bit off topic for gap seals but, in brief, a Lightning can be registered under
the national GA (VH- prefix) registration as an experimental where the builder
(or subsequent owner) is solely responsible for airworthiness and the builder
(while still the owner) can do most maintenance. These aircraft can basically
be anything that one can dream up and build, similar to the U.S. experimental
as I understand it.
The RAA registration (19- prefix) is not a national registration (is not recognised
outside the country). The intent of the RAA registration is similar to the
U.S. LSA rule, again as I understand it. There is a weight limit (544 kg for
homebuilt), two place, fixed gear, single engine, maximum stall speed but measured
with flaps etc in use, no maximum speed so no need to go through the propeller
fiddles for certification. Again, owner responsible for airworthiness
and owner builder can do most maintenance. RAA has a flyoff period but no formal
test requirements and I am not sure of the rule relating to development
of an operating handbook.
Pilot qualifications for these are administered by the RAA under delegation and
currently does not allow entry to controlled airspace but rule changes to allow
this with appropriate endorsement training are in work. Medical requirements
are basically fit to hold a drivers licence and no medical exam required.
For the Lightning it would be relatively easy to move from VH Experimental to RAA
19- registration and accept the reduced weight but not so easy to go the other
way.
Hope that helps. Cheers, Selwyn

Good thought! I had vaguely thought about offsetting the frame edge onto tape
on the acrylic then trimming from that in a similar way to the way the book suggests
the cowl be trimmed but marking it up on the bare frame sounds like a good
idea.

You can use this fashion but becarful as the canopy will add some
thickness
to the skins and they may not sit correctly on the frame. We have glued
the
canopy on, than taped it up good so as not to scratch it. Than fit the
skins
off of the aircraft, put a cleco in every 2=94 or so to hold in place.
Trace
the lower skin on the frame. One done take the clecos out and put the
canopy
back on the aircraft. Trim the frame long from the tracing enough to
cover
your gap between the frame and fuse. Cleco back on and continue to block
sand the edge until the gap is what you like. To get the upper tirm
line.
Take the skins off, measure from the bottom of the frame to half way on
the
flange which the canopy was glued, measure this every 2-4=94 all the way
around and transfer to the skins to trim. This gives about =BD=94 or so
left to
feather the frame into the canopy or a nice look. Of course this is
only
one other way to do it.

Hi All,
I have been struggling with getting the canopy skins trimmed where the
acrylic is glued to the canopy frame. What I should have done and now
recommend to you is, after the canopy frame is trimmed and mounted
(hinged
and gas struts installed) but, BEFORE you glue the canopy to the frame,
clamp each canopy skin to the canopy frame and trace its outline both
top
and bottom of the frame on each canopy skin. This will give you a good
reference point for trimming the skin at the top of the canopy flange.
The
bottom needs to be trimmed after the skin is glued on to achieve that
close
tolerance fit we all want.

Back in the day ... we used to use 3M book binding tape on our Titans. It
is a 2 inch wide clear tape that is thicker than the normal scotch tape..

Bummer, perfect timing. I glued my canopy to the frame Monday evening. I
have been thinking about how to mark the upper edge of the skin for trimming
but haven't come up with a good idea. I drew a reference line on the canopy
an inch and a half above the upper edge of the frame. I plan to measure
back down from the line an inch and 3/8th when the skin is temporarily
clamped in place to establish the upper trim line on the skin. Your method
would have been a whole lot easier.
