About this Plan

Tiny FF gas pylon model. K&B Infant power.

Quote: "This tiny and novel free flight has wowed the boys at last two Nationals with its breath taking performance under power. Build, fly one for fun.

Here is a small model to give you all the thrills and fun of a contest type pylon model with a minimum of effort.

The Funster will give you a terrific rolling climb with a fast but very flat glide. The average glide is usually only two to two and a half minutes on approximately 20 seconds of engine run; however, many flights of ten minutes have been made.

This vest pocket model is the development of about two years of trial and error of various types and designs, to a stable and highly responsive type of aircraft The climb for its size is fast; when properly adjusted it will shoot up at about 2,000 feet per minute, and will give some of its big brothers a good run for their money.

Being so small you would expect the Funster to be tricky to fly. due to wind and other evils. This is not so as it will hold its own in a wind with most any size model. Because of its fast climb it seems to cut through the wind like a knife.

Construction is simple. First is the wing. Cut two panels from medium soft 1/16 balsa sheet. Sand lightly, top and bottom surfaces with 200 to 280 sandpaper and round leading and trailing edges. It is not necessary to sand in an airfoil as usually done for solid wing construction as the slight under-chamber will take care of this. Wet the top half of the wing panels only and, when the wing reaches approximately 1/8 off the table, pin in four places until dry.

If there is a large electric roll ironer in the house, the job of under-cambering the wing is easily done by soaking the wing panels in water, then rolling them through the ironer at about the same temperature used to iron silk or rayon. The wing will come out dry and under-camber set ready to use. Next cut the two tip panels as shown and fit for polyhedral. Pin inside panels flat to table and cement on tips, raising them 1-1/4 in off the table. Set the wings tip to tip; this will assure both sides being equal. Join the two halves together raising each one a 1/2 in at the polyhedral break and cement well all joints.

Cut four fuselage sides, using pattern and carbon paper to trace with. Pin all four pieces together and sand equally. Sand edges at a 45 degree angle to assure a good fit. Spot cement the four small ends together and wrap with a small rubber band. Now cement balance of all four sides and work into place, wrapping with rubber bands about every inch. Cut and insert sub-firewall, set in with 3/16 downthrust and 1/8 left-thrust. As fuselage is drying, cut remaining pieces to shape and sand lightly..."

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.
