Building the cowling was another
challenge. The full-scale cowling is
aluminum and hinged on each side of
the fuselage with piano hinges. It pulls
down to cover the engine compartment.
On the port side, the cowling flares
out to partially cover the external oil
reservoir. Then it bolts to each side of
the bottom of the fuselage, both fore
I constructed it from three pieces of
1/64-inch aircraft plywood, which I cut
to shape with heavy scissors. I doped
the outer sides and covered them with
silkspan, then added several more coats of
clear nitrate dope, sanding between coats.
I added standard Du-Bro nylon
control surface hinges. Between these
I installed 1/16-inch diameter brass
tubing that I scribed with a razor blade
to resemble piano hinges. These were
epoxied to the inside of the covers. The
entire assembly was then fastened to the
upper fuselage with wood screws.
The Tiger Moth was covered with
Solartex from Balsa USA. I’ve used
this covering on other airplanes and it’s
outstanding material, both for the ease
of application and for its beautiful finish.
I simulated the wing and tail rib
stitching by pushing Titebond aliphatic
Right: This photo shows several features of the
empennage. Rudder dual pull-pull cables run
along the outside of the fuselage from beneath
the forward cockpit. Elevator pull-pull cables
emerge from the fuselage beneath the anti-spin
Inset: The tail wheel assembly
is constructed from plans
drawings using brass and
aluminum with a fake spring,
fabricated by wrapping soft
aluminum wire around a dowel.
This close-up shows the
wing attachment brace, the
turnbuckles on the external
double rudder cables, the
tie down for the forward
wing guy wires, and the
weathered wing walk.
The spinner was turned
from an aluminum
block with a metal
lathe. I modified a stock
wooden propeller to
resemble the original.
Note the backward-turning propeller, a
curious characteristic of
the Tiger Moth.
Below: The Tiger Moth sports a novel aileron
pushrod arrangement. The metal disc is
activated by a pushrod inside the wing. When
the disc turns, it moves the aileron pushrod
back and forth to move the aileron.
