About this Plan
Bullet. Free flight sports power model. Simple profile all-sheet construction. For .5 - .8 cc power.
Quote: "BULLET WAS BUILT to provide a simple all-sheet sports model which would have a reasonable appearance and yet be easy to make. If you are looking for a rest from that super built-up job, this one can be built in a few evenings. It's the sort of model to take along for fun between more serious flying and is very suitable for the newcomer.
The original flies around comfortably with an 8 x 8 Frog plastic to keep the revs on the Merlin in check and to give a nice steady climb. Although the wing loading is around 9-12 oz/sq ft a quite reasonable glide can be obtained and the job seems pretty rugged; what is of particular interest to the flat-dweller is that it packs up easily for transport.
All sheet construction lends itself to a good finish and in spite of a fair amount of colour dope it weighs a little under 11 oz.
Wings. First cut out the 1/8 in sheet ribs all the same size as the root rib. Cement two pairs of two ribs together to form the two wing roots. Now space ribs over the plan and pin through the rib 'tails'. Also put steady pins either side of the rib at mid chord. Pin and cement the 1/8 in medium hard sheet leading edge strip. This should lie easily on the flattened front part of the ribs. Take the soft 1/16 in sheet for the centre area of the wing; do not cement to the ribs yet but only along the rear of the leading edge strip.
When set, the part-finished wing may be carefully removed from the building board to enable a good cement job to be made of the ribs. Return the wing to the board after applying the cement and pin down the curvature. Add the trailing edge piece of medium hard balsa and leave to set. Now take the wing off the board and sand down the step formed where the 1/8 in sheet butts against the 1/16 on the top of the wing. This should blend into the curvature. Use a small sanding block and work along facing the L.E.
Sand down the root rib at an angle to allow for the dihedral and fix the 4,-in. ply wing root facings. Ignoring the protruding rib tails, cover the top surface of the wing with lightweight tissue. Dope upper and lower surfaces and return wing to build-ing board and allow to dry out thoroughly. Finally cut off the protruding ends of the ribs and chamfer off the rib under surface to the trailing edge. The wing has now a sizeable built-in wash-out of incidence.
Make the wing struts from split pieces of garden cane, bind on and cement the wire attachments and when dry sew the wing and wire to the under-side of the appropriate rib.
Fuselage. This scarcely warrants any description except to say that a good firm grade of light balsa should be chosen. Do not omit the binding or sewing through the fuselage especially at the under-carriage well to prevent bursting. Cover fuselage with lightweight tissue, after sanding..."

Supplementary file notes
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsFantastic job you are doing Steve, thanks for preserving plans such as these that I've never seen before. This could be easily modeled in modern sheet foam and made to fly with miniature R/C gear and either electric or nitro motor.

* 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.
