BMJ-B-307
In 1921 the Sperry Aircraft Company produced a thick cantilever monoplane wing
which was specifically designed to be interchangeable between the U.S. Curtiss
Jenny, and Canadian Curtiss Canuck, advancing these bi-planes to
state-of-the-art monoplanes. The wing was internally braced, in one piece and
completely free of external bracing wires. Construction used stout “I”
section spars giving the wing a safety factor of 15 before failure. The high
efficiency of the wing and reduced drag over the wire braced biplane
configuration, provided significantly improved performance. The BMJR kit was
inspired by an FAC Peanut by Doc Martin flown at
Palm Bay
and a construction article by Dave Lindstrum published in the Sept. 1995 issue
of Model builder Magazine. Model has a 30” wingspan and 187 sq. in area, is
intended for electric power, with full 4 channel control. With a wing loading of
about 7 oz / sq ft we have flown this model with both brushed and brushless
motors.
