The Airframe
Returns:
It was certainly
enjoyable to bolt my nice, clean, painted airframe together; knowing
that we had previously fitted and drilled all the parts. All nuts
that were permanent were torque sealed at the time, so that any
future movement could be monitored. I should mention that, as
this is an American helicopter; all measures are in Imperial units.
Suits me fine, as I grew up under that system and can tell the
difference between a 3/16" and 1/4" drill much more
easily than I can with millimetres !
The rotor
head is installed at this time and then we start the fitting of
body panels. All of them are curved but there is a logical sequence
to it. We start with the seat back, then move forward via the
floor, tub, windscreen, door posts; moving back to the doghouse
on top and the rear panels. Some panels need cutting and all is
held together with cleco bolts. There is some sanding and filling
to get the shape right and Kevin's workshop nouse is always at
the fore. He uses cotton flox in the epoxy for anything that needs
strength and automotive type body filler for simpler jobs, as
it dries quickly and is easy to sand. During this process, the
tail boom is added and the whole machine starts to look like a
helicopter.
Any rare
mistake Kevin should make is referred to as "an error of
judgment" but you will see from the photos that my numerous
errors are not so kindly described !!
It was certainly rewarding to sit in what resembled the shell
of a helicopter, in the knowledge that one day soon, it would
evolve into the real thing. Then we took it all apart again, to
begin installing the machinery.
During this
building period, I have started my flying training with Helibiz,
here at the local airport. I don't have a helicopter licence,
so am enjoying learning to fly the Robinson R22 Beta 2 ; similar
to the Rotorway but not as forgiving in many ways, which makes
it an ideal trainer. It's a lot of fun learning to fly -- a helicopter
is just so much more exciting than the fixed wing aircraft at
my aero club. A helicopter can do a bewildering number of manoeuvres
-- quick stops, hovering in tailwind and all sorts of things that
are impossible for fixed wing aircraft.
So -- installing
the engine comes next !
