Fly Baby (oz1537)
About this Plan
Fly Baby. Fee flight floatplane. Plan from the April 1945 Model Airplane News.
Quote: "Performance plus realism makes this ROW Class A hard to beat. Fly Baby, by Lieut Peter M Bowers.
RECORD-SETTING gas models that look like real ships are rare enough these days, but when they are seaplanes as well they are almost miraculous. Fly Baby was not designed to be a record breaker, but rather to be a simple plane to build, and one that would be a steady and consistent flyer. It was this consistent, rather than spectacular performance that enabled this little ship to establish the first Class A open ROW record under the new rules. In spite of occasional duckings, Fly Baby was able to keep flying and build up the necessary three flight aver-age.
The engine used in this case was the Madewell Mite, although the model has flown with many others, including the Brat, the old M&M, and the Ohlsson 23.
For versatility, the ship can be flown either as a landplane or a seaplane, without any change of major adjustments or the adding of additional tail area, giving a year 'round flyer. Another advantage inherent in Fly Baby is its small size, making it possible to carry it to the flying field in street cars or busses, an important point to consider in view of present gasoline restrictions.
Finally, we have appearance which should be a welcome feature to those realists who like their models to look like real planes, especially when fitted as a hydro. The author is one of those who believes a model can possess both looks and performance, and offers you Fly Baby as proof of his contention. She's an easy ship to build, fellows, so dust off the old work bench and let's get going!
FUSELAGE: Enlarge the plan of the side view and lay it on your work bench, being sure to place a layer of waxed paper over it before you begin construction. Pin the 3/16 square longerons in place and fit in the diagonals. Note that aft of the cabin these are 1/8 square, necessitating construction of a right and a left half for the fuselage. The smaller uprights should be flush with the outside 'of the fuselage when it is assembled.
While the sides are drying, trace and cut out the two front bulkheads from the material indicated on the drawings. Make the front landing gear strut of 3/32 music wire, solder it to a small piece of sheet metal, riot aluminum, and bolt it to bulk-head No.2. The landing gear must be in place before the fuselage is assembled, When the fuselage sides are ready for assembly fit them into the notches in the two bulkheads and insert the 3/16 square crosspieces as far as the back of the cabin. When these have set, pinch the rear of the fuselage frame together and cement it. Now cut and fit in place the 1/8 crosspieces. The advantage of this type of construction is that the wood fits into its own natural curve and helps to produce a stress-free, and consequently a warp-free fuselage.
Cut out and form the forward cabin roof and fit it in place: Fill in the windows with 1/16 sheet balsa and cut the openings to the proper shape. Fit a piece of celluloid around the cabin roof former and bulkhead No. 2 and then add an outline of 1/32 sheet balsa.
If it is desired to make the ship a sea-plane, a piece of 3/32 inside diameter tubing should be fitted to the floor of the fuselage just forward of the fourth upright. Metal is preferred, but with the shortages a satisfactory tube can be rolled from paper. The fuselage of the original Fly Baby was covered with 1/64 sheet balsa, which in turn was covered with however, a single covering of silk or Silkspan paper is sufficient.
TAIL SURFACES: These are built by enlarging the plan to full size and using it as a layout. All curved parts are full size on the plans. Do not taper the leading or trailing edges until after the surfaces have been built, at which time a sandpaper block will give best results..."
Note this is a scan of the original drawings as published in the magazine pages in 1945. Not a full size plan, it will need scaling up.

* 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.
