This toy of 60/70, is a playful approach to the world of flying odjets, especially that of kites. I found intact in my memory as my children (who forty years), we relived their holidays in Vendée, my grandchildren to whom I have offered (5 and 6) were immediately enthusiastic, and do quits as soon as there is more wind.
No batteries, no electronics, no engine, they crossed, without aging the generation gap and gathered them for long hours of laughter and joy. Of course we must learn to send messages to the pilot until the load is too heavy and causes a crash, or a paper parachute detaches when it reaches the plane, this is the opportunity to speak Aircraft, lift, strength of the wind, clouds and sky, as many lessons learned things in good humor, effortlessly.
A little tip, the first flight remember to attach the nylon thread to the coil to avoid losing the craft, and do not forget a roll of tape (scotch) for repair of tears of the wings or fuselage, as the toy is quite fragile. But with a little care and a lot of "dressing" it can Erte used long enough.
