New AM Cabin Duration (oz4168)
About this Plan
New AM Cabin Duration. Rubber model.
Quote: "The New AM Cabin Duration, by Bill Dean.
This the 97th design from Bill Dean's drawing board, is a revival of an old favourite which has never failed to arouse interest. With latest construction methods and use of commercial plastic propeller and wheels, both appearance and performance are even better than before!
BACK in 1941, one of the writers' first magazine designs the AM Cabin Duration (oz4190) appeared in the August issue of the Aeromodeller. Its neat semi-scale appearance soon made it one of the most popular models in the APS range, and over the years many thousands have been built and flown. Looking over the plans recently, we decided to simplify and generally clean up the design in order to bring it into line with present day constructional trends. The result is this completely new version of an old favourite The 'New AM Cabin Duration'.
Simple stage-by-stage instructions are to be found on the next two pages. Before you start construction, let's pass straight on to flying hints.
Check glide first - adding or taking off nose weight until a stall-free flight path results. Adjust the wing trim tab to give a gentle right turn. When satisfied with the glide, wind up 125 times (clockwise), and launch the model into wind from shoulder height. If the model shows a tendency to spin in either direction, check carefully for warps as these are usually the cause of erratic flight. Gradually work up to full turns (about 350), correcting any tendency to stall by increasing the downthrust. Average duration when fully wound is about half a minute, but longer flights are possible in thermal conditions
Follow this simple stage by stage construction:
1. Begin by cutting out all the parts, tracing or pin-pricking the patterns onto 1/16 and 1/8 in sheet, garin along the longest dimensions. VChoose soft sheet for the tailplane and fins - to keep the tail light. Build up formers 2, 4, 5 and 6 flat on the plan..."

User commentsHi Steve, Many thanks for the New AM Cabin duration plan - I've been looking for this one for a long time! Maybe I'm not seeing this right but there's formers F1 - F3 on the plan but the other fuselage formers appear to be missing. Any chance you can put a call out to get these? Thanks,

Attached is a photo of my AM Cabin Duration in uncovered state, built a year or so ago from original free plans in 1952 Aeromodeller [model photo]. Almost the same as article photo but in colour! Model is now clothed but as yet unflown.

hi steve, i built the am duration in 1976 , from the original 50s plan. it performed admirably, and was flown to death over the long hot summer we had that year. it flew superbly right off the board. after building many keilcraft and veron dime scale models that never really got off the ground so to speak this was a real eye opener. i might just have to build it again. all the best and thanks again,

I built this in about 1962 and it was great. Now going to build another !!

* 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.
