About this Plan

Sky Hopper. Rubber sport model.

Quote: "If you think gas models have a high rate of climb then you should see this Class C rubber job point its nose up and go. Sky Hopper, by John Neustadter.

NAMING this contest performing rubber powered model SKY HOPPER was quite appropriate, for the original design, of which the model pictured above is the latest development, has been hopping all over the New York sky for the past five years. Although this latest model has, to date, never entered any contests, its consistent dead-air performance makes it a strong contest- contender and, what's more, a super all-around pleasure flyer.

With well over 500 flights to its credit, the job is still zooming up into the wild blue yonder - and turning in an average time of better than 2-1/2 minutes per try. In recent tests conducted by MI editors, the SKY HOPPER'S average time for five flights was 2 minutes 46 sec-onds ROG, the best time being 3:15 and the lowest 2:26. With but 150 hand turns the time aloft always topped 35 seconds!

SKY HOPPER can be built by anyone knowing the difference between a wing and a tail. Perhaps the fuselage, with its octagon cross-section, is a bit more complex to build than that of the conventional 'box' type, but with a little care no difficulty, should be encountered. The cross-section shape is one of the reasons why the SKY HOPPER'S climb closely imitates that of a rocket.

Construction will require full size drawings, which can either be made by enlarging the plans on these pages or else sending to the MI Reader Blueprint Service for exact full-sized reproductions made from the original plans. The fuselage is built up from hard strips of 1/8 in square balsa. The heavy lines on the plans indicate the basic fuselage framework, on to which the longerons are placed.

First form one side of the fuselage by pinning the 1/8 in square longerons over the heavy lines, and then cement the uprights in place..."

Quote: "Steve, This plan is from Mechanix Illustrated magazine, March 1946 issue. For several reasons, I decided to purchase the original magazine pages, and put the plan together. Wingspan is 30in."

This plan was published too on booklet "Model Builders' Manual No.4" - 1950 Fawcett Publication. The editor of this and other Fawcett booklets was Larry Eisinger, a famous modeller that (for me) designed the most elegant Old Timer airplane of all the time, the "Duchess" of wich there is on outerzone the italianized version "il Duca". Larry was one of the most prolific editor and is considered the Father of Home Improvement booklets. His intersting story is on internet and youtube. I'm not surprised if he still around. regards,

* 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.
