Many of us fly cheap airplanes, but few fly anything as cheap as the Multiplex Fox.
Looking a bit like a scaled-down Multiplex Easy Star, it’s sold as a $15 glider: no motor, no control surfaces. Throw it hard and high and wait for it to come down.
But it looks so much like a small version of the planes we fly that inevitably people began tinkering with it.
Matt Abrams had the first one I saw. His was blue, a work in progress on the day I saw it at the PCC airfield.
Mehmet had sliced out elevator and aileron surfaces from the horizontal stabilizer and wing.
He said he bought three and was going to experiment until he came up with the best configuration.
Next came Dennis Castleman, ever the innovator.
Dennis simplified his controls by independently pivoting each wing on a carbon fiber rod, rotating each one with a servo, allowing the wings to serve as both elevator and ailerons. He powered his plane with a 12mm Feigao inrunner motor and a small press-on propeller.
He glued solid carbon fiber rods along the center of gravity of each wing, then mated them to a carbon fiber tube buried in the fuselage.
His build was the cleanest I’ve seen so far, and his plane was quick and nimble in the air.
Its only drawback, he found, is that it falls out of the air when he slows it down: it stalls quite easily.
If Dennis, Mehmet and other inventive builders can tame it into slower, more stable flight, this is a good candidate for combat sessions.
Multiplex foam, which they call Elapor, is a bouncy and durable isotope of EPP, perfect for destruction derby flying.Airplanes, Baylands, Combat, Flying.
