Lube Tube (oz1983)
About this Plan
Lube Tube. Rubber powered contest model for beginners. Dec 1971 Aeromodeller.
Quote: "A 41in wingspan rubber powered duration model for beginners or newcomers to competitive flying.
Having flown Coupe d'Hiver class models for two seasons, the author deicided that he would like an Open rubber model of roughly the same proportions, but with much increased performance for flying in local and club competitions, and so with these thoughts in mind, a model having a rectangular sheet fuselage was quickly completed. With a motor run of approximately a minute, it performed quite well despite lacking a good glide, and while the fuselage proved to withstand motor breakages and landing on rough areas outside the flying field, it was obvious that the whole model needed to be lighter.
The second version presented here is virtually the same, but features a rolled sheet fuselage. When trimmed it has a good climb and three minutes have been exceeded many times. We do not pretend that this model will out-perform larger open rubber models, but Clive has flown Lube Tube successfully over the last two years both in contests and just for fun. The model rarely goes off trim and is as tough as one could hope for, while its simple construction is ideally suited for the beginner, and would form a perfect introduction to competition flying. If you would like to try a flying winding tube, read on!
Fuselage construction is really simpler than it looks. Firstly, choose a light straight-grained piece of 1/16 in sheet, 6 in wide, and cut it to the length of the main motor tube. The width of the balsa blank is determined by wrapping an off-cut of sheet around the former to be used, such as a broomhandle. This sheet blank then has a layer of light-weight tissue doped on one side, and is allowed to dry. Immerse the blank in water for about ten minutes, then wrap the soggy blank around the former, tissue side inner-most, and bind same with bandage or tape of some sort, to form a tube. Do not attempt to cement the seam at this time. Allow to dry for 24 hours so that all the water is evaporated....

Notes
* 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.
Scaling
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.
