About this Plan
Tipo. Free flight sport model. Wingspan 36 in, for 0.5 to 0.8 cc diesel engines.
Quote: "Your Premium Free Plan feature. Find the challenge of free flight with this 36 inch charmer for .05 to 0.8 cc engines and featuring a quick-build Jedelsky wing. Tipo, by David Boddington.
Radio Control Rules, OK? No, not really. R/C is, without a shadow of doubt, the main interest of aeromodellers these days, but it isn't the only type of aeromodelling worth pursuing. Flying an R/C model is challenging and requires considerable skills. Free flight flying, where you have no control over the model, probably needs more skill and aerodynamic understanding than any other branch of the hobby. It is both challenging and rewarding. 'Tipo' is a simple model to build and a good introduction to free flight activity.
It begins here: The only decision you have to make before starting on the construction is to decide which engine you are going to install. Although a diesel is to be preferred because of the ability to set the engine at a safe consistent operating speed, a Cox 'Bee' glo motor could be fitted. If you want to convert it to two function (or three) then modify the fuselage formers to cope with the linkages and allow for elevators to be cut from the tailplane. It is doubtful if it would be very suitable for electric power - but you could prove us wrong. ]
Cut out all the parts, selecting wood quality carefully, check the engine bearer width to suit the motor you are using. Sand the underside of the wing panel sheets thoroughly before commencing construction, it is difficult to get at these areas after the ribs have been glued to the sheeting.
Fuselage: A simple box sheet affair, first glue the upper and lower sheet side parts together, then glue on the insides the doublers and longerons. Also mark the locations of the formers. Glue formers F1 to F5 in position (the undercarriage is bound and epoxied to F41 checking that the bearers are a good fit to the cut-outs in the formers. Use a slow drying epoxy (1 hour Speed-Epoxy) for gluing the bearers into position.
Pull in the fuselage sides to the rear, gluing the formers in position as you go, pin them to the sides until the glue has set. Sheet the top and bottom of the fuselage with 1/16 sheet, add the 3/32 windscreen sheeting and make holes for the wing dowels.
Sand the fuselage and add the sub-fin, it slots into F10.
For the wings you should pre-shape the leading edge sheet to a reasonable degree before fitting, the final sanding can be completed when the panels are completed. Pin down the ribs, with the pins at the extremes ie outside the sheet area, the root ribs must be angled for the dihedral. The 1/16 sq strip to the trailing edge of the wings and leading edge of tailplane) is for more ding-proofing' and is optional.
Join the wing panels, packing up the tips for the correct dihedral, the brace is fitted into slots cut into the root ribs. Reinforce the centre top joint with a piece of glass cloth, bpdage or nylon, glued into position with adhesive (white glue or aliphatic) epoxy resin, or dope. The rib ends are trimmed at the leading and trailing edges, but not on the underside, note that the W2 ribs sit either side of the fuselage.
Tailsurfaces: No need for explanations here except to say that parts of the fin slot into the tailplane and fuselage and that the anti-warp insert really does work.
Finish: Dope and sanding seal the wings and tailplane and sand smooth, it is only possible to decorate the top surfaces of these components, this can be done with tissue or self adhesive colour trim vinyl. The fuselage and fin can receive the same finish treatment, or they can be covered with tissue or film. Keep decoration to a reasonable minimum. Fuelproof as necessary.
Flying: Balance as shown on the drawing, go out to your flying field and commence flight tests with glides. Procedures for trimming out free flight power models are described in this issue, so there is no point in repeating them for 'Tipo'.
Just watch the amount of fuel you are using and remember to add a name and address sticker. Now go ahead and organise a club free flight scramble - that will sort out the men from the boys, or the other way round! "

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

Notes
* 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.
Scaling
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.
