Slo Poke (oz13071)
About this Plan
Slo Poke. Free flight sport model. Optional power pod.
Quote: "A study in slow-motion flight in various forms: powered job or glider with tail first or tail last. Slo-Poke, by Gabriel Bedish.
IF you've wanted to build a sure-fire, out-of-the-ordinary addition to that roster of fine performers for weekend get-togethers, Slo-Poke fills the bill for both novice or sport flying enthusiast. The design also is intended for transition by the beginner to high-performance without having to start with a Nordic model. Our model is close to Nordic specifications for learning to fly models of Nordic size.
Slo-Poke is a simple model which performs well above average in several roles. It is relaxing to fly. Powered versions are ideally suited to the Cox 020 Pee Wee, which takes the model well up in a smooth turning climb.
Cost of building Slo-Poke is about $3. The original model is still flying after years of fun, with no repairs beyond a few punctures in the covering.
Construction: Medium-hard balsa is used with exception of hard balsa for fuselage longerons. The framework is light but rugged. Conventional construction is used in a manner to enhance efficient streamlining.
Use enough cement in assembling the framework if you want a long-lasting model. Fuselage construction is begun by assembling two sides directly over the plan. Wet the balsa longerons where curved before pinning them down. Allow the glue to dry thoroughly before removing from plan.
Insert the top and bottom crosspieces, working from rear to front. Upper and lower sheet-balsa keel-type stringers, taken directly from plan side view, are put in place. Notch out keel stringers for fitting over crosspieces. Add the numbered formers. Put in wing and stabilizer mounting dowels, the mount rests and sheet balsa fill-in around the mounting dowels. Add attachment receiving pieces for engine as well as dethermalizer. Tow control is optional. If utilized, follow the plan drawing for installing parts.
A landing wheel can be located into the front underside, or you might prefer a soft copper-wire skid, added after covering the model. Both are easy running for ROG flights. Streamline the wheel well with a carved balsa fairing. Plank in the nose section. Carve and hollow the nose block for snug fit over the retainer piece mounted to the front of the fuselage frame.
The wing is a fairly standard form construction, with medium-hard quarter-grain sheet balsa planking along the upper for-ward surface. After separately assembling the two panels, plank both. Dihedral is added and the wing center-section soft-balsa block shaped and affixed to secure the dihedral. The block adds strength. Attach carved tips at the outer extremities of the panels, as well as those pieces next to the center section.
Construct rudder and vertical fin by laying out outlining pieces and vertical inner brace over plan. After the unit is dry, remove from plan and fit the horizontally cambered braces by bending the lengths around the vertical inner brace. Cement them. Rudder tabs are carved from balsa and set in position. Soft sheet metal is used for the trim tab. The tow control tab is mounted on celluloid, while a small music wire (.040) horn is placed as shown.
Of streamline cross section, the sub rudder is formed from sheet balsa, to which is attached a soft copper-wire skid. A length of wooden dowel is placed as indicated to limit dethermalizer travel.
Stabilizer construction is similar to the wing. Our unit is hefty to withstand striking objects, also because it has generous area.
The balsa engine pod is put together as illustrated in the schematic drawing. Nuts for the engine mount bolts are cemented to the rear of the firewall. Recesses in the balsa pod permit room for bolts and nuts. Fit of the pod to fuselage mounting should be snug.
There is no timer for our model. To add one, install either an eye-dropper variety behind the engine firewall, or measure the fuel placed into the engine tank..."

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

The photos printed in the article are confusing, I agree - and the 2-colour paint job on the tail fin makes it even harder to 'read' the black and white pics - but yes, this is indeed a model that can be flown both as a conventional layout plane or as a canard.

* 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.
