About the Balsa Racer CS
During the summer of 2006 I discovered the Airfield Model's Design & Build Contest. This seemed
like a contest for me, without reading the
rules I thought, 'Cap 20L', 'Turbo Raven' or maybe a 'Giles.'
Then I read the rules… What? No scale airplanes… bummer (or so I thought at the time). I spent the
next few months trying to figure out what to build, biplanes, 1930ish monoplanes, propjets, canards. During
this process I must have sketched a dozen different models, neither one of them intrigued me enough to build.
By this time it was April 2007 time was growing short if I was going enter the contest.
Perhaps the oldest cliché is “necessity is the mother of invention” and it was true in this case. Our local
modeling club, The St. John’s R/C Flyers were going to host a
pylon race on June 9th. The rules were simple any ‘conventional’ single engine airplane with a 40ish motor (or
smaller) and fixed gear.
The club held several building seminars to build SPADs. Those heavy ugly coro constructed machines were
invading, yuck! For the race I had a little 20 size balsa plane I had scratch built many weeks before.
During the third flight of the plane I spun it into the ground — total
It was now 2 weeks before the race I needed a plane. The Balsa Racer CS was born “CS – CORO Sux.”
It took two weeks from design to flying plane.
