About this Plan

EDO Floats. Plan showing construction (only) of floats to fit the 51 in span Lanzo Puss Moth (oz440) model.

Quote: "Rubber Scale EDO Floats, by Hal Cover. The Puss Moth, or most any scale ship for that matter, on floats is a thing of beauty and a joy forever. Use these scale Edo jobs as a basis for putting your model on the water.

With the past flying successes experienced with the updated Lanzo Puss Moth (oz440) it was a natural to add floats. Edo floats 1 inch to foot scale (June 1938 Air Trails) were selected for this purpose.

Initial flight tests illustrated only one problem, a slight tendency to dutch roll. Fin area was added to correct this. All other flight adjustments were left alone.

Several items should be kept in mind when installing floats on any scale model. First, is the correct location of the step in relation to the center of gravity. It should be located slightly ahead of the CG, 2 to 3 percent of fuselage length. Next, the float angle should be 1.5 to 2.5 degrees positive to the thrust line. It is also important to mount the floats firmly so no movement can occur.

Construction: Cut out two keels from medium 1/16 sheet - don't forget to cut out the center as shown. Four of each former should then be cut from medium 1/16 sheet. You will notice that formers No.3 and No.5 show notches for the inner float struts, but only two of the four formers require it. Glue the formers to the keels, making sure they are in line with each other and at right angles to the keel. Glue the two upper 1/8 square stringers to the No.1 nose former.

When dry, glue the two stringers in place to each former. Always work with both stringers at once, otherwise it will be difficult to keep the float keel straight. Attach the bottom stringers in a similar manner. Sand all the 1/8 square stringers to the correct former contour..."

* 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.
