Shorty (oz1892)
About this Plan
Shorty. A/2 class towline glider, with a snub-nose design.
Quote: "Jeff Hancock's snub nosed rally winning A/2 glider.
Bora Gunic started the short nose glider fashion when he flew his BG.44 (oz4333) to first place in the 1952 A/2 at Graz in Austria, and quite a few modellers followed his style by massing all the ballast in as short a nose as possible. Among them was Jeff Hancock of the Surbiton club - a regular competitor of note in all London area events and close companion of Pete Buskell, John Barker, etc.
Jeff, decided to go 'ultra-short' early in 1954 and started a series of contest wins to outline the value of his approach. At the Croydon Gala he placed first with 12:00 (maximum total). At Northern Heights, he tied for first place with two five-minute max's then slipped to third with a poor fly-off time, and at the Radlett meeting he came second.
To start the ball rolling right for 1955, fourth position in the closely contested Blackheath Winter Glider contest—only 6 sees, short of double maximum time with 5 = 54—was proof indeed that "Shorty" is still in the groove for the coming year. Jeff uses a one-piece wing; but details are given on the plan for separate halves as an aid to transport. One thing about this A/2 design is that the fuselage will comfortably fit any model box!
The Fuselage is constructed on the former F4, and the lower 1/4 inch square hard balsa lower longeron. Cement to this the tow hook, bound to hard 1/4 inch balsa, and also add the d/t hook. The vertical formers F1, F2, and F3 are next cemented in place. Add the former F3 and the top 1/4 in square hard balsa longeron, taking care to chamfer the end of the longeron where it meets the lower longeron at the rear of the fuselage; also cut the slots in the top longeron to accommodate the fin, which is added at a later state of construction.
Position the auto rudder arm, and attach the nylon thread auto line. The sides, cut from medium soft 1/8 inch sheet, are added filling in around the nose with 1/16 inch sheet balsa, having a hole to pour in the lead ballast weight. Add scrap block balsa behind the rear wing mount position, and before adding wing mounts and dowels sand the whole structure smooth and round of sharp edges..."

Dear Steve, I've just finished a 36" Shorty by scaling up the plan from the original Aeromodeller magazine. I first built one in 1955 when my father brought me my first Aeromdeller as a 6 year old - but I Simply cut out the wings and tailplane from 1/32 sheet with scissors - it flew! My latest version almost 60 yrs later follows the plan exactly [see more pics 003]. Covered in Jap tissue it weighs 54 grams of which 27 is the cast lead nose weight ! First flight was on Minchinhampton Common using my friend Robin Kimbers bungee -7.5 ms of 3/32 rubber 22.5ms 15 lb fishing line. It towed beautifully but with such a narrow chord wing the duration was not outstanding. But it's such a stylish and elegant model who cares?RichardFalconer - 24/05/2014

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.
