Strutter plans and parts.

The large tail make ground handling easy. The strutter excels in take off, touch and go, and landings.
My 1/3.6 Strutter is flying really well. It won the contest at Warboys, getting the best static score
and also beating all the 'Flying Only' models flight scores. At Merryfield it was quite windy
and mine was the only biplane to risk flying. It got the second best score and other pilots were
impressed with the models ability to perform in gusty conditions.
It won the next contest in gusty conditions, and scored 10's for landing and touch & go.

Laser 360. 22 x 10 prop at 6700 rpm, 10 kg thrust.
Cowl is 300 mm inside diam.

My strutter is painted with our polyurathane spray can paint,
PC10 colour. With lazer glow engine, at seven years old, the paint was still
good except for a small patch at the botton of the cowling. I just dust this over
from the can once a year.

Kits are 100% scale. Many times contest and championship winners.
They feature working scale rigging, and quick assembly for flying with no loose screws to get lost..
The rigging wires are made from stainless steel spring wire, to scale width and thickness.
Very strong, rustfree and does not get kinked in handling. The scale forkends are fitted in
pairs to each end of the rigging wires. Tension is adjusted as on the original, release the
lock nuts and rotate the wire to adjust. When dismantling the model the tension setting is
not touched. Each time you assemble the rigging setting remains constant. The lightweight
scale wheels are mounted on scale split axles with scale bunjee elastic for springing.
Our original models used 30 cc Laser V twin engines. They will fly on a calm day on a
wisp of throttle, but the larger engine size allows for a big propellor to be used at low RPM.
This gives a more realistic sound and extra power is in hand for vertical climbs and for flying
in very strong winds, which is necessary for a contest model. Our kits have been flown in
the scale world championships by pilots from France, South Africa, USA, Spain, Sweden,
Norway, Italy, New Zealand, Scotland, and England.
Kits contain
:-Plans, Balsa strip & sheet, hardwood Spars, Longerons, Glassfibre leading edges,
hardwood Struts, CNC cut Wing & tail ribs, Ply formers, Ply deckings, Light alloy sheet for panels,
Piano wire, Doweling, Wire U/C with axles, Bunjee elastic, Hinges, Plastic sheet, Scale wheels,
Alloy cowling, Dummy Clerget engine kit, Machine gun kit (2 for Camel), Stainless Steel fittings kit,
Rigging wire, Forkends, Silver solder & flux, Eyelets, Bolts, Screws.

Instructions for forkends.
Pour a liitle flux powder on the bench.
Touch the end of a long screw to your tongue
and dip in the powder.

Hold the screw in pliers on to the rigging wire and melt the solder together.
Hold it still until the solder sets. Check alignment and resolder as needed.
slight bent angle can be corrected by just warming the solder until it softens
and you can bend it straight.

1. Cut flat rigging wire to length minus 20mm.

2. silver solder right threaded stus to wire.

3. fit lock nut & forkend, try in place on model.

4. Cut flat wire if needed, solder left thread stud to wire.

5. fit fork end, aim for half the thread showing so some adjustment
is available.

The solder can be filed smooth and blended in to the wire.
A cheap grinder with a polishing wheel is good for this.

Battling the gale at 2004 Nats ( a jet model landed just before this -'Too windy!)


My 1/3 scale Bleriot.
Span 115". length 101". weight 10.5 kg [glow power]

I had the first flight with this model, powered by Hacker B50 17XL brushless motor with 6.7:1 gearbox and 32 x GP3300mah
cells which fitted exactly inside the scale brass fuel tank..
The model had 4 kg of nose ballast with total weight of 14 kg. Thrust on a 24 x16 prop was 15 lbs at 4000 RPM. CG was 35%.
Model flew well with enough power, but batteries ran out after 4 minutes.
For the second flight I removed 11/2 kg ballast and flew with less throttle than before. Duration was then 6 minutes.
I expect I could have improved a bit on this time, but for contest flying at least 12 minutes are needed, so I decided
electric power could not do the job without more battery capacity. [now lipos are getting cheaper, this would be the way to go.]

I fitted a Laser 360. This gave 20 lbs thrust at 5000 rpm on 24 x 12. With the ballast removed the model was only 10 1/2 kg and flies very well.
With 860cc of fuel in the the scale brass tank I think it could stay airbourne for more than 20 minutes.
It will float along on a wisp of throttle, but with nearly 1:1 thrust to weight it will deal with 25 mph winds easily.
The model lands very well and is very stable on its wheels. I did not try it, but I think it might loop!

The wings come off for transport. The tail can be removed, or the rear fuselage with the tail, which takes less length in the vehicle.
We carried the whole fuselage with rudder in a Mondeo estate, the rudder resting on the rear view mirror.

I noticed that photos of the prototype at Old Warden show about 30 degrees of UP elevator being used. My model requires
quite a lot of DOWN elevator for level flight, which suggests to me that the full size machine is flying much slower. I wonder if the engine
is lacking power. The wing warping is said to be no good at all, but my model works well with the warping except when the
airspeed is very low.
I have since seen of photo of the full-size in normal flight- Yes, it had down elevator just like my model!

Assembly of Sopwith Pup for flying. Takes about six minutes.


Lower wing panel is plugged in.

The first landing wire is connected

And the second - No loose screws.

Aileron linkage to servo.

Strut plugs in.

Then top wing plugs in.

Front flying wire- tension is automatic.

Second wire through the wing

Aileron link wire.

Ready to fly

Rigging our Biplanes

1. Wings are carried in four flat panels, easy to transport.
2. On assembly the rigging tension is automatically set.
3. All screws are captive on the model.
4. Tail and U/C are also removeable.

1 1/2 Strutter assembly for flying.

All the wing rigging wires are left connected on the top wing,
with an elastic strap to hold them neatly.
Plug in the centre side struts (stored in the cockpit)
Fit the top wing onto the struts, then onto the pins at the root.
Secure the top wing with the sliding wire from the rear.
Plug in the bottom wing to the fuselage.
Connect the2 landing wires.
Plug in the two outer struts to the bottom wing.
Lift the top wing and fit the struts in place.
Screw the 2 flying wires to the fuselage sides.
(The wire tension is automaticly applied.)
Connect the aileron wire.
That is five screws each side. All are captive on the model.

I have this genuine piece of fabric from a Sopwith Camel

Camel news. June 20th 2001. I took down my twelve year old 1/3 Camel and shovelled off the dust.
The model weighed over 14 kg and I wondered if I could cut the weight down to meet the new FAI limit of
12 kg for F4C competition. I made calculations several times, but it always seemed impossible. Finally I started
the attempt. The metal dummy engine weighed 875 gms. I remade this in plastic and got it down to 200 gms.
The steel axles with cross-over drive were put back to the original alloy ones. The broken metal guns were
redone in plastic. Pilots body and dash were removed. The spark ignition system was removed and I fitted
glowplugs and small battery in its place. Lots of odd bits were removed and some wood cut away. .
I cut away some parts of the homemade 80cc V twin engine to save 400 gm. The model is now under 12 kg.
What about the CG? I made a balsa box above the engine, weighing 6 oz. This carries two polythene bags
which hold 3 1/2 lbs of fuel to bring the CG forward. In competition, the fuel is drained out before the
weight is checked. Crafty!
Strutter news. Sep 2002. At the Team Trials 2002, the wind was strong, about 15 MPH.
We needed to fly so that the Britsh team for next year could be selected, so we began the contest.
My 12 year old small Strutter was the last to fly. By then the wind had risen to 25 MPH, too windy for most sports models.
I was thinking 'I must be mad to risk a slow flying scale biplane in these conditions, wish I had the Spit or Hurricane
which were also competing, or better still my jet Lightning.
The model would not stand still on the ground. I had to put on quite a lot of throttle to prevent it rolling backwards, and
the tail came up. The model was at flying attitude and speed on the ground. I waited until the model stopped moving around
for a moment, then opened the throttle further for take-off. Holding the Strutter on the ground at higher than its normal flying
speed gave a good take off. Having plenty of power from the Laser V enabled a good flight including a touch and go and a
long straight landing for the best flight of the day.
In future, when we get a windy flying day, I wont say "wish I had my Jet model" but instead "wish I had my old Strutter!".

2005 My big Strutter now comes into the F4c class at just under the 15 kg limit. It has been decided that the Strutter must be
considered as aerobatic, so I have rearranged my schedule accordingly. I am happier doing aerobatics.

2008. The big strutter met its end. I got out the old 1/3 Camel. Fitted a 100 cc flat twin petrol and the model flew well at 14.7 kg.

2010. Now building a new Strutter, slightly smaller to keep under 15 kg. 3.6/1 scale, 112" span. Looks like it will be 3 kg Under the limit!
