the windows, I used a flange from Tower Hobbies that actually grips
the Lexan window from both sides, and provides a flange to glue to the
Each window is first rough cut, then
taped to the opening. I then scribe a line on the plastic
1/32" inside the opening. This allows for the thickness of
the window flange.
To accommodate curves, you make little
wedge-shaped cuts in the flange, on the inside of the curve only,
working around the entire periphery of the window. These cuts,
as well as the joins will be filled in (as well as possible) using a
water based black bathroom caulk. Just smear it into the cracks, and
wipe off with a damp cloth!
The windows are affixed
with Canopy Glue, which looks a lot like Elmer's, but is acrylic
based. You can clean it with water until it cures, which makes
it easy to apply and clean up. Once the window is placed and
glued, it is taped down for 24 hours. Adjacent windows have to
be done over two days. It takes about 1 1/2 hours to properly
fit each window.
We tinted the upper
windows (as in the real Heli), by adding a mix of green and blue
Tamiya paint to automotive clear, then sprayed the inside surface of
the Lexan. It came out very, very nice!.
