About this Plan
Flinger. Radio control hand launch glider.
Direct submission to Outerzone.
Quote: "Here’s another glider plan (HLG) for Outerzone. It is the Larry Jolly Flinger HLG. At a 57 inch span it is in the 1.5 meter A class of gliders. With 300 sq. in of wing area, an estimated weight of 13 ounces and with an Eppler 205 airfoil it should produce an excellent performance glider. I’m sure modern radio equipment could cut a couple of ounces off the weight. A review of the Flinger is available here https://rclibrary.co.uk/title_details.asp?ID=2292.
I’ll be building this one first as stock to fly in the SLNT (Soaring League of North Texas) Class A Man on Man scramble. We use a 50 meter high start for this event, 25 feet of yellow Theraband tubing, a streamer or small parachute and enough line to make it overall 50 meters (164 feet). One helpful trick to get a little extra altitude is to 'Ping' the model off the high start; just as it nears the top of the climb push the model down to gain speed and then pull up to 'Ping' it off the line. Push the nose over as it climbs and level off at full height and you will get 20 to 30 extra feet on the launch.
Later I’ll build a second model using a Graupner 400 11.1v brushless and a Graupner 6 x 3 folding prop. The motors are pretty rare these days in the US but you may find them in Europe more commonly. Both of the models will include an adjustable tow hook. I’ve also tried the Hobby King B20-40-28L 2030Kv brushless with the Graupner prop (6x3) and it works quite well. I run it on a 3S lipo and get about 100 watts of power for most of the run. It hauls my 13 ounce Kastaway to 400’ in about 15 seconds or less.
Best wishes to all,"

User commentsGood morning Mary and Steve. I always start my day by going to OuterZone to see what treasures you have found to share with the rest of us. Today I woke to find a young me looking at old me!
About the Flinger it is a great all rounder well worth the small build time involved but will give that investment back in the form of hours of satisfaction. My usual recommendations are in order. Lengthen the nose an inch and narrow up the formers to appropriately house your electronics. Better for you older Teenagers, put one of the small 2S Emotor sets up front,and forget the Chiropractor and Cryopacker
...being English you might enjoy some Trivia concerning the name. Flinger, it is short for Fling Her. In a skit from the 70’s the Monty Python Lads are seen Launching a Cat off a Spinning Ceiling Fan. John Cleese is the normal BBC Suit and Eric Idle is his usual innocent unaware simpleton. John Cleese makes a comment like “Well that is very interesting. And just how do you get the cat in the Fan. Eric looks up with child like Round Eyes and quips, Uh I just Fling Her...
Please enjoy and Thank you for Preserving this design. Dad would be pleased. He signed this one by the way. His J’s were always far better than mine.

* 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.
