About this Plan
Windbag. Unorthodox free flight spot model. Wingspan 9in, length 31in. For Cox Babe Bee 0.8cc power.
Quote: "Looking more like a Martian spaceship, Colin Read's wingless wonder is nevertheless a practical flying model guaranteed to attract a crowd wherever it is flown.
ALTHOUGH being of an entirely new layout for an unorthodox model, some design experience has been obtained, mainly in the U.S.A., with this type of machine. Perhaps some of those who wit-nessed the flying sessions at the Northern Heights and South Midland Rallies wondered why it flew at all. Well I, myself, am still not too sure as to why it did!
The principle factor in giving sufficient lift to fly is a light structure of minimum size capable of maintaining lift. Absolute stability is built in and any variation in trim will still give results, ie less negative tail incidence gives a faster, more level flight, more and it will stall turn all over the sky and still the engine will cut-out way up!
The most suitable power units are the DC Bantam deluxe 0.8 cc or the Cox Babe Bee 0.8 cc. These, of course, are radial mount and feature integral fuel tanks, but any 0.5 cc diesel can be used, provided a suitable tank arrangement is built in. Engines such as ED Baby; DC. 0.5 cc, Mills 0.75 cc. and AS 0.5 cc can all be mounted with no trouble at all. The fuel tanks can be dispensed with and an eye dropper type of tank used to limit engine runs. Perhaps a TD .049 contest version would do for open power, who cares if it glides, just think of the height which a model like this can obtain in 10 secs!
Construction is very simple and can even be completed in one evening. Cut out all the fuselage formers and the eight nose pieces (S1). Cement eight strips of a 1/8 in sq to the S1 pieces and set aside to dry. Cement formers 2 and .r to these stringers, pin where necessary to hold whilst the cement is drying, then add F3. Should an internal fuel tank be considered, ample space is provided behind F2 and no trouble should be found.
When the front end of the fuselage is quite firm and all joints well cemented, add F5, F6 and finally F7, then join the rear of the fuselage together. All 1/8 sq cross braces can now be cut out and cemented in position as shown on the drawing, followed by the 1/16 in end sheeting.
The tail mounting is next built up and the squareness of the fuselage checked. The 1/16 in tail surfaces are covered and doped before cementing in place, although holding them on with a rubber band is satisfactory for initial flight trimming. When trimmed cement in place permanently to avoid any trim changes..."
Quote: "Hi Steve and Mary, I hope all's well over there at the Outerzone ...Cleaning out an old filing cabinet recently I found some more plans from the 1960s, mainly magazine foldouts, some of them do not appear to be in your database. Here is the first one, Colin Reads' version of Roy Cloughs' Martian Space Ship. I have removed a few smudges and cleaned up the text a bit, hope it's OK for listing. Cheers,"

* 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.
