Little Clinker. Small CL biplane sport model for 1.0 to 1.5 cc engines.
Quote: "Reminiscent of bygone barnstorming days, this bipe will thrill you with its realistic appearance and snappy performance. Little Clinker, by Phil Powis.
While designed primarily for an .074 engine, any good 1/2A engine may be substituted. Note the wide tread on the gear, insuring ground stability, and the general sturdiness of the model itself, capable of withstanding the occasional minor mishaps incurred in a day's flying.
Sport flying makes up most of the average modeler's activity, and it was for this type of flying that our Little Clinker was designed. With the right prop, speed is high enough to be interesting, while response to the controls is quick and easy. At the same time, the ship has sufficient wing area to allow smooth, gliding landings, resulting in few smashed props.
While the Little Clinker was designed around the Cub .074 engine, other crankcase-mounted engines such as the Wasp or Cub .049 can be substituted. Wing span is 19 in and length about 16 in. Plans are printed half size and must first be scaled or photostated up to full size. Articles in previous issues of Flying Models have covered the scaling up of plans - we suggest you refer to them.
FUSELAGE: Cut the fuselage sides and bottom panels from medium-hard 1/16 sheet, and the formers from hard balsa of the specified thickness. Indicate all former positions in pencil, and lightly crack the sides at former 5, as shown. Note the fuselage sides are notched at the front for the cowl lugs. Cement former 5 to the bottom wedge and add the fuselage sides. Install formers 6 and 7, cement the sides together at the tail. Note the 1/16 sheet wedge at the tailwheel location. Formers 3 and 4 are then installed, followed by the wing mount and doublers. Add 1/16 square diagonal braces to maintain alignment.
Now make the bellcrank mount of 1/4 sheet balsa and 1/4 plywood as shown, and bolt the plywood or a 2 in Veco bellcrank to the mount.
TAIL : Cut the stabilizer and elevators from hard 3/32 sheet and sand to a streamlined cross-section. Cut the elevator joiner from tin-can stock and cement into slots cut in the elevators. Solder the control horn to the joiner, then hinge the elevator assembly to the stabilizer with conventional cloth hinges.
CONTROLS : Hook up the controls and install the stabilizer and bellcrank mount in their correct positions. The two-piece pushrod is made of 3/32 dowel. A wire fitting is now bound and cemented to each end for attachment to the horn and bellcrank. The overlapping ends of the pushrod sections are then cemented together, between stations..."

* 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.
