I have been an aeroplane nut as long as I can remember—I think I
inherited it from an uncle who was involved in models in the
1930’s—and started building models as a boy. Remember the old Keil-
Kraft rubber kits—Playboy, Orion, Ajax etc? I built most of them. By
the time I had reached mid-teens I was building free-flight scale and
own-design models powered by motors like the Mills .75 and the ED
Racer and A2 class thermal sailplanes of about 72" span. I have found a
couple of surviving photos from that era—the first is me in 1958 with a
Thermic 72 sailplane and the flying shot also appears to be a the
Thermic 72 but as yet unpainted.
Towards the end of this period I even did some experiments
in radio control with a single-valve super-regen receiver and
rubber powered escapement to drive the rudder. The idea at
that time was to build a stable, well balanced free-flight
model and attempt to influence its course with the radio. I
remember installing the gear in a scale Tiger Moth, but I
don't remember it ever working properly. That receiver and
escapement survive, I found them at the bottom of a carton
of junk, but not the transmitter with its single central pushbutton.
By the time I reached my twenties I had moved on to other things – full-
sized aircraft (I got my PPL) and then boats. I never lost my interest in
model aircraft though, but it was only after I retired that I got
back into the hobby.
Things were very different after 40 years; radio control had
changed. I now have a 4 channel fully proportional receiver
that weighs less than 10 grams, a quantum level smaller and
lighter than that old receiver, and there are all kinds of
wonderful new building materials on the market
I tuned up my building skills on a number of simple rubber
powered models, and then went on to build a couple of slope-
soarer gliders. (for the uninitiated: all gliders need rising air
currents to remain aloft; thermal gliders use the rising air
currents created over warmer parts of the landscape, slope-soarers use
the rising air created when wind has to pass over a hill. With modern
radio control both types of model can be kept in the rising air-currents
so flight times are limited only by how long suitable conditions remain)
This island is perfect slope-soaring country as we have nothing but hills
— a good way to learn to fly radio-control.
And now I am back to designing and building flying scale models of
planes from the early years, but this time electrically powered. Electric
power is quickest growing area of the hobby with new batteries and
motors producing more power for their weight every month it seems.
And we no longer have the noise and mess of the old internal
combustion engine.
