Simple Simone (oz10651)
About this Plan
Simple Simone. Control line tainer.
Quote: "Most control-line events nowadays are flown on 2 lines in a counter-clockwise direction. Did you ever try to find a trainer for this? There is one of course, but most have to be modified in some manner. Makes it a little rough on a beginner who is completely green about everything including the engine, tank and basic truths about yo-yo operation. Anyhow we decided to try one. The result was Simple Simone (she's a lady), one of the smartest li'l ole planes you'll ever meet.
Flown with a 19 engine it feels like an airplane, while not tearing around like a rocket powered bat. Speed isn't much over 45 per. Knows where the circle is and stays there, but won't break your arm. Takes off by itself and is steady enough for wheel rolling and handkerchief pickups. Excellent for balloon-busting, and it's cheap. Designed for the 19, it will handle a 35 with a thicker fuselage, although then it goes like a bat.
We just finished flying it with a new Fox 15 in a 20 mph wind, and it flew like a veteran. Of course this engine really puts out for its size. Both of my ships have been piled in many times with no significant damage, due largely to the fairly slow speed. A 35 would probably break it up if piled in 'cause that way it will turn over 70. We use 60 foot .012 dia lines for everything which gives you a fairly slow revolution and very little dizziness.
Most fascinating aspect is that Roberts Throttle installation. We used the bellcrank, handle and three .010 dia. cables, coupled to Bob Smurthwaite's Vari-Speed throttle. (If ye usend him your engine and 4 bucks at 2460 Clark St., Baker, Oregon, he'll fix you up right - it isn't a home job unless you have proper equipment and a few years experience at machine operation.)
With Bob's throttle, the flight pat-terns are infinite. For instance, it will slow-fly under 20 mph, land, stop, and take-off at your whim. The ship has no bad habits under any condi-tions of rpm or acceleration. It sim-ply responds to a boot by speeding up smoothly. No wild climbs or dives from a misplaced thrust line.
Simone is simple to build and built to last. Makes an excellent club train-er; our throttle job has logged over 200 flights with 1500 landings and take-offs, and appears ready for 200 more. The youngsters put in as much as 2 hours a day without shutting the engine off. They even let ME fly it every now and then. So shall we cut wood?
Carefully trace the outline of the nose section on 1/2 in Fir Plywood. Cut out for engine to suit the one you've got. Mark the tank saddle holes, throttle slot and gear mounting holes. Do likewise for rear fuselage on 1/2 x 4 in medium balsa. Extreme accuracy is necessary on the surfaces to be glued together since they determine the wing incidence and angles. Do the job on a jig or band saw if at all possible. Check that they mate properly then sand rounded edges. Set these aside for a while.
Carve the wing as shown on plans. A model maker's plane is excellent for this. Try to shape as closely to plan as possible - make a template on cardboard to check with. The tips are shaped up from the bottom..."

* 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.
