At some time in the 1950’s,
the Eastern Suburbs Model Aero Club (ESMAC) obtained the plans for a 60
foot line radius Carrier
Deck, complete with arrestor ropes, superstructure, etc. It is pictured
here at the Albert Park flying field, on the edge of the
lake. Contestants were scored for a low-speed run, a high-speed run, then
a successful landing on the deck with arrestor hook
dropped and extended.
The Roberts third-line control system was used
almost exclusively, with only a couple using the
floating bellcrank system.
Unfortunately, following construction and when fitting the ropes,
the designed 5 pound weights were apparently not available, |
but 15 pound ex-window-sash weights were! So, three ropes were attached to
just one 15 pound weight at each end - 5 pound
per end per rope - right?
The result? -
An effective 30 pound arresting weight per rope instead of
the designed 10. The error was eventually discovered,
but only after countless models had their arrestor hooks ripped out! Even
models using only their undercarriage for being
arrested suffered damage.
This deck was subsequently used for many, many years until it literally
rotted away. |
