Test Flight Report
Having had trouble with the two stroke twin, then two burn outs with electrics, I fitted THE perfect engine for the model,
Bought second hand at the Nats. The four stroke OS four cylinder engine is amazing. It starts on one or two flicks, and runs on all cylinders through the flight,
Even doing snap roll at idle. Power was enough to climb vertical for some way, cruise around at 1/2 throttle.
All manourvres went well, spin, stall turn, avalanche, etc. Over-shot on landing with the idle set a bit too high. Delightful!
Model weight about 11 1/2 kg, Engine turns 19 x 10 prop at 6700 rpm.
No need to tune very lean for max power, slighty rich was fine. The 1 ltr tank was needed.

We have heard of other kit models of 1/3 RF4, where the wings collapsed in flight.
This model, with ProSkin covering was able to perform very violent snap rolls, left and right, with no problem!

53 cc Flat twin twostroke.                        Now changing to a flat four cylinder OS 320 engine. Perfect scale!!
                                                           Exhausts are now joined together on the top, to port side scale exhausts.

I printed the cloth as 1/3 copy of my own shirt, and sewed the model shirt

I came acroos an old movie of the World Championships 1978, with some shots of my RF4
I was impressed! by what I had managed to do the!.
.All the cockpit equipment worked.
Moving the throttle operated the tacho and oil pressure gauges
The compass worked. The turn and bank gauges worked.
The temperature gauge worked
The ASI worked from air pressure in the pitot tube.
The altitude gauge worked from atmospheric pressure.
The elevator trim tab moved, from handle and gearbox in the cockpit.
The handbrake operated, with ratchet locking.
The red test light indicated the glow plug was good.
The stall warning light worked from th tab on the wing LE.
The earphones on the pilot, plug into the dash and pick up radio two.
And we had no home computer or printers then?
and the pilot (Me) was dressed in cloth corduroy trousers and woollen sweater,
and secured with working seat belts.

The model needs a minimum of 16 metres solartex.  

Most models of the Tiger have the wings as two sets with the struts attached. This takes a lot of space, especially in 1/3 scale.
My aim was to produce an accurate scale model, but made easy to build, and easy to rig the on the field,
whilst making the wings dismantle into four seperate panels for easy transport.
We have now achieved this with the rigging in the scale positions.
The wings are attached with only six screws, which are all captive on the brackets. The model can be rigged in five minutes.
The tail can also be removed if needed.
Our prototype flew with the same electric power set-up as our big Spitfire and Bristol M1.

hat makes a classic? Its that indefinable combination
of good looks and performance which combine
to set the standard for others to follow.
The Classic
often copied but never bettered has long
been a favourite with thousands of modellers.

GANGSTER 63 classic

The Gangster 63 is renowned for its smooth flying characteristics
It will perform advanced manoeuvres with a 50 to 60 engine
yet is suitable as a first low winger for novice pilots with a 40 engine.
It can fly incredibly slowly without stalling with a flying weight 2.5kg
Veneered foam wings and sheet balsa fuselage and tail as
it was in 1970, wire legs are in the kit but you need to supply
fuel tank wheels & hardware.
Classic Gangster 63 kits made in small batches for keen builders.
2022 price 195


Much lighter than the the classic Gangster. Model was tested
with an 20 year old 40 engine. It showed all the qualities     
of smoothness and predictability of the original, and was
also very aerobatic. With the CG at 3" very small loops
and knife edge were possible. With the throttle well back
and full up elevator, the model would fly along slowly
without stalling. The CG on the original was 1" further
back and this would give a livelier model for the expert pilot.
Flying weight 1800 grms.
Basic Kit with cowl, canopy & wire legs 125

Epoxy cowling 10. wheels, hinges & horns pack 11

Gangster 52 Classic

The original Gangster 52 kit like its bigger brother is loved for its aerobatic performance.

This is my first model boat ever. 70 years ago, at seven years old, I saw a picture of a boat which took my fancy.
I decided that I should now realise my desire (Steady!) by building one.
So the design is 'scale' but only a far as I can remember.
The prototype model had its maiden run, and was very successful, with 1 1/2 kg ballast at the stern.
It reach a good 'planing' speed, and my 5 AH, 22 volt lipo would probably give an hour running time.
Motor, 5040. 270rpm/volt. 6 cell . more than enough power. Good fast runs at 3/4 throttle.
Tried with total of 8 1/2 kg ballast. A bit slower, but lower in the water and the spray pattern
at the bow did not look so good. I will go back to 1 1/2kg in the stern, and the 1 1/2 kg battery amidships.

The superstructure just lifts off in two parts, to give quick access to the whole interior.
Two lifting handles are provided inside. This makes lifting by one person easy. No need for a special harness to set it on the water.
The prototype model was finish very quickly, using self adhesive vinyl sheet in white and red, and dark woodgrain for the cabin sides.

The Party in the back has Mike Myers playing the banjo, whilst the girl dances.
