My Airplanes Before 1998
I've been interested in model airplanes since I was a little kid, and
in 1992, I started building them in earnest. In 1994, I taught myself to
fly. I currently (1997) have two flyable airplanes, and one pile of wreckage.
All my airplanes are electric powered. No gooey fire-breathing noise
makers for me. Typical power is around 150 Watts input (about 1/5 HP).
Wing span ranges from 46 to 78 inches (1.2 to 2m).
Below is my lastest plane. It's called the Fred's Special, in
honour of the designer's dog (named Fred). It's a medium-performance sport
plane, and can do loops, rolls, hammerhead stalls, and stuff like that
(I'm not that good at it yet). It also flies quite fast (up to around 40mph)
and is a bit more of a challenge to fly than my glider(s) (see below).

I built this plane, from scratch, using plans from a magazine article
(Model Airplane News). Like all of my planes, this one is built almost
entirely from balsa wood, and covered with a heat-shrinkable plastic film.
Wing span is 46.5". Weight is around 51oz. Power is a Graupner Speed
600 8.4V, a home-made high-rate speed controller, an 8x4.5" folding
propeller, and a 7-cell 1400SCR battery.

To the right is my first airplane. At the time of the photo, it was
a glider (it had no motor, and was launched by means of a 300 foot long
sling shot). This is the plane I took the various aerial photos (see below) from.
The plane is a Carl Goldberg Gentle Lady. Wing span is 2 metres.
Weight is around 24oz. I have since modified it for electric power, which
has raised the weight to 47oz. Power is a Great Planes Goldfire motor,
a home-made on/off controller,
an 8x4.5" folding propeller, and a 6-cell 1400SCR battery.
The photo shows what can happen if you accidentally hit the control reversing
switch on the transmitter while launching the plane.

The Gentle Lady is no more.

On June 16, 1996, this plane crashed. I was doing some aerial photography
with it, and it suddenly went haywire. It went into a spiral dive and hit a
cottage roof (no damage was done to the cottage). Analysis of the wreckage
suggests that the crash was caused by corrosion in the negative lead between
the receiver and battery (the same crud you get on the negative terminal of
your car battery).
On the flight prior to the ill-fated one, I successfully took some aerial
photos from the plane, using a Kodak Disc camera, which used a film disc
that could should 15 frames. Here are a couple of the photos:

This Great Planes Spectra was the replacement for my Gentle Lady.
|
Next, we have my second plane. It is very similar to the Gentle Lady,
but was designed for electric power. It's the first powered plane I flew.
The plane is a Great Planes Spectra. Wing span is 2 metres. Weight
is around 58oz (a bit on the heavy side). Power is a Great Planes Goldfire
motor, a home-made on/off controller,
an 8x4.5" folding propeller,
and a 7-cell 1400SCR battery. This photo was taken just before it's
maiden flight (at which time it had an 8x4 fixed propeller). After flying
this for a couple of years, I rebuilt it into something lighter and
more powerful, the Spectra-V.

A scratch-built scale Piper Cub that never flew.
|
This photo is of a Piper Cub I built in 1993. It never got
off the ground due to lack of power (a very high-wind Mabuchi RS-550; I
didn't know much about motors back then) and lack of skill. I crashed it
while taxiing around, but I may build a new wing and put in a new motor
some day. This plane was scratch built. Wing span is 48". I don't
recall the weight.
Here's me (on the left) and one of my friends discussing/admiring the
gentleman's Simprop Excel. The photo was taken in Halton Hills,
at the
Electric Model Flyers of Southern Ontario
fun-fly.
