John
Hill of Leeds completed and successfully flew his De Havilland
Canada Dash 8 - a twin engined propliner - a few months
ago. In a recent letter, he gave the following
information :-
"The
Nimrod PSS design inspired me to have a go, mainly because of
the construction technique, i.e. foam fuselage, which has
produced a very realistic model. The difference on my
Dash 8 is that it is a thick white foam/veneer type instead of
the box clad with blue foam on the Nimrod.
The
nose section is epoxy glassed, which takes care of the
compound curves. The rest is veneered in Obechi, except
for the short curve between the parallel centre section and
the rear tapered section, which was also glassed with epoxy
direct onto foam. The sketch below says a thousand
words."

Dash
8 foam fuselage construction explained by John Hill. |
"The
model is 1/10th scale, 100" span, fuselage 88" long,
AUW 12.5lbs giving 30oz/sq. ft. wing loading. Finish is
in Solarfilm. RC is 3 function - Rudder, Elevator and
Aileron. Ailerons have differential movement to avoid
adverse yaw. The tailplane and nacelles are detachable -
the latter allows access to aileron servos in the wings.
The wing is 3-piece with full depth spar with 1/4"
diameter high tensile steel joiners in brass tubes and 12
gauge incidence pins. The wing is held in place by thin
dowels and wing bolts."
