About this Plan
Sans Egal. A2 glider model.
Quote: "Finland's finest A/2 glider for several years. Sans Egal by Reino Hyvarinen.
DURING THE LAST four-and-a-half years this leading Nordic country's A/2 from the Finnish Champion modeller, has flown in eleven national and four International competitions. The lowest placing has been 8th and last year Sans Egal won four major competitions, including a winter event at Hanko in ideal conditions with 900 secs, the Chrysler-Plymouth meeting at Whitsun with more than two minutes lead over the next of 37 entries, the Finnish Nationals in strong wind, and most important, at the Nordic Countries Championships in Norway in rain the glider won with 90 seconds margin. This displays the excellent all-weather characteristics which make it so very suitable for the normal English climate. Its still air average is 2:45 - 2:50. Thermal hunting and holding characteristics are good and the wing is very strong (it has never broken in towing).
Hardwood is used for the wing spars and fuselage longerons, which give elasticity and strength, they provide a long life for the model, and are very essential for all-weather work. However, the inertia of moments are still not great due to careful selection of materials at outer components, for example, the tailplane weight on the original is only 7 grammes (1/4 oz) and the tail-boom is light and flexible. One can, however, hold the model just in front of tailplane and wave it in any direction, thanks to hardwood longerons!
The wing tips are laminated to their elliptical shape from 1/8 in strips, and the necessary carving is done after assembly. The section changes to a straight bottom at the ultimate tip and it is quite easy to produce the washout when carving TE (and LE). Special care must be taken to get the wing tips light by balsa selection. Centre panels of the wing are easy to make, first notch T.E. and fasten rims to it not forgetting to pack up with 1 sq in..."

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.
