Tipsy Nipper. A 24 inch span, free flight scale model for .46 - 8cc. From Aeromodeller, May 1959.
Quote: "Full-size plans overleaf for CC Badger's model. Build a Tipsy Nipper.
AS A MODEL PROJECT the Nipper catches the eye because of its simple lines and ideal proportions. Though rather heavy at eight ounces for its 24 in span, the model flies fast and is tough enough to withstand those early trimming prangs.
Construction of the wings is quite straightforward following the normal ribs over spar technique, trailing edge, then leading edge additions. Ensure that correct amount of washout (1/4 in) is in each wing panel (made separately) when pinned down for doping. Note that the rear wing dowels are short and the dowel holes in the fuselage are at different heights so that the port (left) wing has a greater angle of incidence.
Start the fuselage construction with F,2 and glue the dowel box to it, next fit the 3/32 in thick sheet balsa sides to the former and also add F.3. Whilst this assembly is drying, glue the ply nose former and engine bearer onto F.1. Now bring the two assemblies together and fill the space between the engine mount and the fuselage side with soft balsa block.
Next pull the rear ends of the fuselage together and add F.4, F.5 and F.6. At this stage the rear dowel plates and the ply support for the rear u/c legs should be glued in position. Now bind and glue the nose leg and the rear leg into position. Next stage is to add the stringers o the top of the fuselage and also the soft block fairings to the base. The Nipper is now ready for the top cowling, instrument panel and the remaining undercarriage leg.
One of the three legs to each rear wheel on the real aircraft has been omitted to save a little weight.
Hinges for the elevator trim tabs can be made simply by pushing a pin right through the tab and into the tailplane and then snipping off the head. The tab can then be bent up or down and will stay fixed. Hinge the rudder tab in a similar way..."

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.
