Little Mavis. Rubber sport trainer model.
Quote: "THIS MODEL USES fairly stout wood sizes for its small size to allow for youthful handling and the anticipated crash (not so far fortunately). It is important to use very soft balsa, mainly because it is easy to cut, but also for performance reasons. Wing and tail leading and trailing edges can be a little firmer, and the ribs are best cut from medium quarter-grain 1/32 sheet, but light 1/16 sheet will do.
The fuselage is assembled in the usual manner. Two sides are built first over the plan, these are then removed and split. Find two suitable blocks, or make up two sheet formers to the width of the fuse-lage between the sides. Lay one side flat on the bench, put the blocks at either end of the parallel part of the fuselage (top view) and use set square to make sure that the top side lays exaotly above the lower one. Then glue in the spacers between these two supports. Allow this to dry, then remove from the bench, cut nose and tail spacers and fit these with the help of rubber bands and pins.
Draw the tail end in also, and cement. Then add the rest of the spacers and sheet parts. Reinforce the rear motor dowel hole with ply or celluloid. Cut out and cement the tailplane mount at this stage.
The fuselage can then be covered with lightweight rnodelspan and doped with 50/50 dope-thinners twice. Then fin the wing mount side pieces and dowels.
The wing is straightforward except..."

* 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.
