Quote: "The Talon has been especially designed to suit the SMAE Rules for combat flying, which limit engine capacity to 3.5 cc (.21 cu in). Other rules concern the streamer and line dimensions which are detailed on the plan. The requirements of a model for successful combat flying include:
1. Quickness and cheapness of construction, in view of the high 'mortality rate' of this type of model in competitions.
2. High speed and good maneuvreability.
To satisfy the first point, a flying wing layout was chosen, being cheaper in materials and exceedingly quick to build. This kit contains almost all parts cut to length or die-stamped and by following the Quick Building Sequence faithfully, the model can easily be completed in 9 - 12 hours including covering. Secondly, the tail-less configuration has less drag and weight than wing-and-tail designs, resulting in higher airspeed for a given power. The maneuvreability of the model is governed by the balance point position and you are best advised to conform to the pos-ition on the plan, even if weight is required at nose or tail to achieve this.
Beginners to C/L flying can safely use a CG location as far forward as the leading edge of the wing, but on no account must the model be flown if the CG is too far back, regardless of the experience of the builder.
On opening this kit, inspect all the parts, identifying them with the plan and Building Sequence. Check that the bearer spacing on the two ply formers is correct for your engine and adjust if necessary. Drill one of the formers to take the tank lead-out. This former will be F1. The other will be F2. Drill the two bellcrank mounts (B1) to take the bell-crank fixing bolt (see plan). It will also be necessary to drill the control horn to take the horn fixing bolt.
QUICK BUILDING SEQUENCE:
1. Using plenty of cement (or better still, hardwood resin-type glue) fix engine bearers to F1. Slide the fuel tank into position from the rear, packing with scrap wood so that the tank lies exactly centrally to the bearers. Now glue F2. in place.
2. Drill bearers to suit engine, mount engine in place, solder-ing the bolt heads as shown on plan. This assembly is shown on the plan by the sketch marked 'STAGE 1.' Glue the fuselage sides to the formers and leave this assembly to dry thoroughly.
3. Mark the rear spar for the position of all the ribs and slide the ribs on to the spar, getting them all in the correct order. Pin them to the spar accurately but DO NOT CEMENT ANY OF THEM TO THE SPAR YET.
4. Pin the leading edge to the fronts of the ribs, and when satisfied that all ribs are parallel and vertical and that the wing is not warped, cement around all joints to the LE and spar.
5. Pin and cement both the 3/16 sq main spars into the wing. Follow with both trailing edge pieces, and once again check that the wing is not twisted.
6. Glue the lower B.1. into place between the two ribs W1. Install the pivot bolt and bellcrank, then add the upper B1... "

User commentsThis was my stunt trainer, very robust and manoeuvrable, it saw out two second hand engines, both died with bent crankshafts. I flew it for well over a year before selling it on and building a Commodore.

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
