Sundowner (oz7388)
About this Plan
Sundowner. Free flight sports model for .020 cu in motors.
Quote: "A 45 inch span free-flight model for beginners, sports flyers or sufferers from nostalgia alike! Sundowner, designed by Peter Scott for .020 cu in motors.
FREE FLIGHT SPORTSTERS never lose their charm - there is nothing quite so relaxing as flying late into the evening equipped with nothing more than a little fuel sloshing around in the bottom of its container, and of course a well charged battery! Vintage flying is another satisfying sport, but the inherent drawbacks are the relative bulk of the models and their potential proneness to damage. Sundowner was thus designed to capture the spirit of the vintage model but on a scale suitable for the ever popular Cox Pee Wee power, and without structural complications or weaknesses.
The resulting model really satisfies these demands and its flight performance proved to exceed all expectations. Genuine rise-off-ground take-offs are easily accomplished over short grass, while landings are equally smooth with no nose-over tendencies. The climb is most stable and the glide impressive - so you really can relax with this model, no will-it-won't-it scares as you release it to the skies!
If you've built a few models before, follow your own favourite sequence; if not, follow these notes and you can't miss - construction really is straightforward.
Commence with the wings, building a port and starboard section in turn; balsa cement is the quickest, simplest adhesive to use for this purpose. Make up the two halves of the main spar, using scarfe joints at the tip dihedral breaks. Build the centre panels first, remembering to angle R1 with the aid of the dihedral template. (Note the TE is best shaped before assembly; and R8 is added after the tip and centre panels have been joined.)
When making the tip panels, prop-up the centre panel by 4 in under R1 to incorporate the polyhedral angle. Some care is needed when making the tip outline from pieces W1 to W3, but the result is very strong; a piece of the same section as the spar extends from R11 down to W2. Add R8, and the gussets, and one wing-half is complete.
Repeat for the other side, then the two halves can be joined by pinning one centre panel to the bench and propping-up the other 3-3/4 in under R8. Add the dihedral braces and the centre section sheeting to complete the wing construction. Sand the LE and tips to section, and give the com-plete wing a light sanding. Cover with lightweight tissue, and give three coats of 50/50 dope/thinners; coloured tissue trim was used on the original to give the 'scalloped' effect (using the last coat of dope to adhere this to the covering), then a coat of fuel-proofer is applied.
The fuselage is very robust. and straightforward. Only a dozen pieces are required, so cut all these out before assembling. The sides are from 3/32 in medium grade straight-grained balsa..."

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.
