Those with a very long
microlight memory may recall the Tiger Cub, a miniature biplane
sold to budding microlighters in the days before Section S. It
acquired something of a reputation for sensitive handling, but did
achieve approval once regulation was upon us. Russ was involved
with the Tiger Cub, and so it's no surprise that the basic biplane
layout was chosen when Russ wanted to produce an updated
microlight. It also produces such a practical microlight, I'm
amazed no-one else has tried it.
Russ decided that going places
wasn't his first priority. His experience in light aircraft told him
that even with the high cruise speeds and sophisticated instrument
panels of a conventional light aircraft, we in the UK are still to a
large extent at the mercy of the weather, so it was more important
to have something that would be cheap to operate and maintain, quick
to get in the air, fun to fly, and good to look at - and for this,
the traditional folding-wing biplane, as developed in the 1920's,
was the perfect vehicle. Remove the four pins from the leading
edges, and the wings fold to make the aircraft towable within five
minutes, thus saving hangarage charges. The taildragger biplane
layout is phenomenally strong, and will stand rough treatment both
on the ground and in the air, and the classic looks will appeal to
everyone and not be subject to the whims of fashion. A kit-built
aircraft will keep the initial cost down.
He took this idea and fitted it
around a bolted tube structure for ease of manufacture, and produced
an airframe of immediate appeal to all aviators. I flew the
prototype in 1995 and was instantly taken with its light handling,
ease of stowage, and attractive looks.
Although the idea was sound, Russ
had problems producing the kit, and only a trickle of kit-built
aircraft have made it into the air so far - four to date from about
a dozen kits sold.
