Here
is an original design of a Dehavilland DH-53 Hummingbird
based from a 3-view I found on the internet. It
has posed some challenges that I am slowly figuring
out
nice solutions. This landing gear shows a few of
those: the nylon friction fit washers and spacers
to retain
the wheels are made from bits of zip-ties drilled
with an exacto knife to a bit smaller diameter than
the
wire.
The gear struts straddle the fuselage
and the middle of the wing. It is only attached in
the
front.
The rubber bands that hold the wing on also act
as a shock absorber.The nose is a network of bluefoam
and balsa and wood putty. The putty is actually
pretty
nice to work with, it is from Elmers and is very
light and sandable like a spackle. It's not pretty
but ...
we'll see how it finishes! The drawing on the
wall is one view of the 3-view found on the internet
from
which
I based the plans. More as it progresses!

| The motor is from a Braun shaver,
but is the same as a speed 280 from a Firebird using
the prop turned backwards (converting a pusher
to a puller) |
This shows how the landing gear
really just dangles from the nose. I am planning
on retrofitting a plank in the bottom of the
wing to take the shock of the rear strut brace.
It feels rigid now but able to break away easily
without damaging the body too much. |
As you might be able to see above,
the motor mount is a network of balsa and blue
foam (and some wood putty) |
