Quote: "Ramsey Flying Bathtub, by Don Drury.
WH Ramsey designed this unusual home built in 1931 and, although it flew very well, the records show that only one was ever constructed. The plane's unusual features included the bathtub type of cabin, seating two side by side, and the Aeronca 30 horse power, two cylinder engine. Complete history, three-view drawings, and de-tails, were published in the June-July 1963 issue of Air Progress.
This little gem is an ideal rubber scale model due to the high thrust line, related wing and tail size, and general moments. Also the combination of open framework and tub gives added eye-appeal and takes the model out of the norm. The amount of scale detail is up to the individual modeler and the level of competition in your area. Two mod-
The condenser paper covered indoor model almost disappears into the background. High thrust line allows generous size propeller.
els were built, one indoor light-weight with condenser paper covering, and one heavier outdoor version with colored tissue and paint trim. Both models were photographed, but the plans are for the light weight version.
Construction is conventional and quite simple. The bath tub is 1/20 sq, or 1/16 x 1/32 sliced from light weight 1/32 sheet. Formers are 1/32 sheet and deck stringers are 1/32 sq. Nose of the tub is light weight styrofoam. Landing gear is 1/64 wire and wheels are, again, light weight styrofoam.
The engine is a tube of 1/32 sheet balsa soaked and wrapped around a pencil. The engine pylon is a sandwich of three 1/16 sheets, and the center piece is out into the foam nose of the tub. Add 1/16 engine nose plate and thrust button and install tail skid and Styrofoam cylinder heads. Cover with condenser paper and tub is completed.
The propeller is made from 1/32 sheet sanded to 1/64 and mounted on hub sections at 40 degrees to the propellor shaft..."

NotFound | help
This is a scale plan, but ScaleType is set as NotFound.
This happens when we can't find a relevant Wikipedia page to link to. Usually because the type in question is uncommon.

User comments
This model (builder/pilot unknown) is being flown during the 1976 annual Peanut Scale competition in Montreal, Quebec [pic 004]. This event was quite competitive, with 15-20 models entered as I recall. No indoor R/C in those days, and peanut scale was very popular. Model Builder magazine published a new full size plan every month to keep us busy!ChrisMoes - 11/03/2021

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.
