Air Cabin Jr (oz6296)
About this Plan
Air Cabin Jr - Radio control sport model. For .30 power and 3 channel RC.
Quote: "As the designer Al Sievers states, why not rediscover how much fun and how relaxing it is to fly low and slow instead of high and fast. This will give you the ultimate relaxation which we all can use.
How would you like to break away from the super high and fast approach to our fascinating hobby? I don't know about you but I'm a bit tired of the guided-missile approach. Shaky palms and sweaty arm pits are reserved for those who don't seem to mind working at play! Why not rediscover how fun and relaxing it can be to fly low and slow instead of high and fast.
The Air Cabin Jr is the product of over fifteen years of modeling, most of that in R/C and several months of doodling on paper. You know what I mean, letting your imagination wander in a meaningful way of course. Certain perimeters were kept foremost during the design, they are as follows:
1. Cabin type, attractive with a touch of realism.
2. 15-18 oz per sq ft wing loading.
3. .29-.35 power.
4. Tail dragger for soft or grass fields.
5. Different looking tail section.
6. Forgiving, stable design, good for training new pilots.
7. Functional door for added realism.
8. Strong yet lightweight.
9. Name and design capable of Quarter Scale.
10. Modified Clark Y airfoil for super lift at slow air speeds.
The Air Cabin Jr was designed for three channel control, making it an ideal trainer. If one wishes to include ailerons, I suggest the strip type as the barn doors tend to produce snap rolls into Mother Earth, unless coupled with rudder and/or differential movement. Furthermore, with the rudder area as designed, she turns on a dime and gives you the change.
If you are looking for that ideal airplane and a hint of nostalgia, capable of low and slow flight to please the crowd and yourself, the Air Cabin Jr will more than fill the bill. Perhaps you are looking for the lost art of relaxation - then you will thoroughly enjoy this unique airplane. The prototype has been flown on calm days, four to eight feet above the ground. (Four feet for straight flight, climbing to eight feet on the banking turns.) I believe they call this flying uki style! One or two wheeled touch and go's are a snap. If that's not enough, try hopping fence posts; the ample elevator makes pitch changes quick and easy.
Since it's still early spring here in Oregon, I can't try out the Air Cabin Jr's thermalling ability. However, with her large wing area and light wing loading, I am certain she will keep pace with the Kloud King (oz5215) and Buzzard Bombshell (oz5360). As for her ability to perform aerobatics, in a word, I doubt it. Someone will undoubtably stuff a 60 in her nose and send her screaming through the heavens; but she will never whisper sweet nothings if you treat her like that. Instead, why not let her fly the way she likes to be flown, on her wing not the engine.
In summary, the Air Cabin Jr is a fun and pleasant flying R/C model aircraft. If built as per the plans and directions, she will surpass your expectations while providing you with loads of relaxation and enjoyment. I am confident you will agree after building and flying yours. Good luck, good building and happy flying!
Prior to beginning the construction portion, I would like to express my appreciation to John Evans, Portland, Oregon, for his professional, calligraphic touch in lettering the name of the fuselage. Now let's stop gabbing, clear the workbench and start building..."

* 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.
