Peres I (oz9255)
About this Plan
Peres I. Free flight towline glider model. A ten foot span sailplane.
Quote: "Designed by Dr IF Piattelli the Peres I is a sleek high-winged sailplane with very graceful lines, the fin sweeping high above the fuselage giving exceptional stability in flight, long wings tapering at the tips ensure a high performance. It is indeed a beautiful model whose aspect promises great things and is constructed with hardwood and veneer throughout. On the original model the mainplane leading edge was sheeted with cardboard, but as ply is obtainable in this country this has been modified. The great strength derived from the hardwood construction has enabled this model to survive many accidents that would have completely smashed a model of lighter build. It is always necessary when using hardwoods to ensure perfect adhesion at all joined surfaces and for this reason a cold water glue should be used throughout the construction.
Ordinary bamboo tissue may be used for covering, but for a really strong job silk or 'Planefilm' is preferable.
The size of the Peres I is : wing span 10ft, length 5ft. The all-up weight of the model ready to fly is only 5 lbs. The model will make a very strong job and one that will give excellent results if due care is taken with the construction.
The model was designed entirely by Dr Piattelli and constructed at the Tel Aviv experimental centre for Aero-modelling and Low-Speed Aerodynamics (Tel-Aviv Aero Club). Dr Piattelli is the Director of Research at Tel Aviv, which is the first established centre in Palestine.
Well known in this country for his popular Kirby Kite, scale model glider, and the AP6 contest sailplane, Dr Piattelli puts before our readers the fruit of much research and experiment. Peres I is an outstanding achievement in the field of the large model sailplane, so little explored in this country as yet... "

User commentsThe plan identifies the designer as F.J. Piattelli, whereas the article credits (Dr.) I.F. Piattelli. It's a minor point, but does anyone know which is correct?

The initials stand for Ing. (engineer) Fidia (apparently a Greek name) Piattelli. He was an Italian aeromodeller and aeronautical engineer. He was imprisoned in WW2 for being Jewish. After the war he went to Israel and continued his career. He made some unusual and beautiful model designs.

* 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.
