Alan Leppanen of Cambridge, Ontario Canada designed this cardboard RC Zero.
The wing has a symmetrical cross section and balsa edging on the tail surfaces and ailerons, laminated for the curves.
The model is powered by a Super Tigre .90 2 stroke engine. Separate channels
were used for each aileron to make setting up differential easy, resulting in 5 channels total.

The Zero has a 78" wingspan, 900 sq. inch area and weighs 8.5 lbs. The canopy
is glass over foam and the cowl is molded fiberglass, split and hinged for easy engine access.
The Zero is Alans third CB model. The first was a 72" span trainer called
the "Cardbird" which he used to learn how to fly RC. His second was a low wing .40 powered RC for sport flying.

Nice in-flight photo. The cardboard airframe results in minimal cost and build
time, but the finished paint job and some detailing definitely give it that scale-like appearance.
