The images of our first model!
In order to begin a warm salute to all the navigators who are it lands to you on these new pages dedicated to the dynamic model of the Japanese fighter bomber Yokosuka D4Y.
I and Pierre are PROUDEST of this realization. We say and not us vergogniamo! For we this realization was an incognito and the resolution , even if hoped, it was not at all sure . I show oneself to the world del' aeromodelling for before the time and therefore ne' I had not never constructed, ne' flown . Pierre e' in the field from years and even if e' an optimal pilot never has instead not had the courage to expose itself to the integral construction of a model . For the report we have known thanks to the newsgroup it.hobby.modellismo (whose participants we pick the occasion in order ringraziare for the precious councils) and have uncovered to live to little km of distance.
The left idea therefore e' from the necessita' of having a model that allowed me to learn to pilot and to Pierre to teach to me without to run great risks and moneies in case of destruction of the same one. The endured choice e' directed towards a model electrical worker perche' I am myself in order to graduate myself in Ing Electronic, with annexed and connected, and Pierre lately has decided to be interested to this world.
The inadequacy of the several one schiumini (than both we possessed) to act as from aerial school after a first approach with the remote control was however obvious. To we fortified tail of rudder of profondita' and direction and the wings with ailerons served something with one ! A fort input in so far as e' arrived to us just from the newsgroup.
To the beginning the choice had addressed towards the semireproduction of celeberrimo the hunting Zero Japanese. Pero' after to have found the first measures of the same one and to have them capacities in the scale that interested to us we have uncovered that it would not have been possible a motorization with Speed400 and propeller in direct, for the simple fact that the imposing snout of the Zero with its radial engine would have fagogitato the poor propeller 6x3 that we had intention to use for the first tests.
To me it would be piaciuto however to continue to be on a Japanese subject and to the end, nearly for case, scovato the first versions of Yokosuka D4Y that mounts an in line engine and very adapted for the characteristics to the motorization electrical worker.
The challenge was launch. They are put to me to the CAD and after little weeks, leaving from a series of trittici it finds to you in net, from the considerations learned on the book " We plan a model aircraft " of Kannenwolf, much documentation reached from the net and from I use of several simulation programs are reached to a plan . Sure my inexperience could make to fear the disaster, but thus e' be. The model flies WELL even if perhaps e' just the prototype of the trainer and does not demand not too much a little use of the inches (but!!).
To the beginning we wanted to use the technique that Martinucci has thus disclosed well (ringrazio also he here for some suggestions that have given me) but then we have opted for a various construction piu' similar to that traditional one with formers, spars etc also adapting it to the characteristics of the materials from we uses you : polistirene for the structure and Depron for the cover (remembered the limited cost).
The thing narcotic of which there are shrewed after to only have completed and tried the model e' the extreme robustness of the same one that, after tens of landings on the belly piu' or little hard, not filler that some graffietti. We have also broken a propeller when the model touching of ribaltato wing e'. But the Yokosuka has naturally not endured benche' the minimal lesion .
The result you can admire it in the many attached photos. There e' to say perhaps that we have put po' too much a time to construct it and rifinirlo, but sapete com' e' with the primogeniti ones! ]
The begun plan e' to you open them 2001 and e' concluded to fine October of the same year. Working an evening to week and adapting the plan to the requirements that were introduced with proceeding of the construction.
That dirvi of piu '? To short seguira' a detailed explanation on the methods you follow for the planning and the construction of the model.
In the meantime you enjoy the images that we have released during makes of assemblage and the flight tests.
Seen the many demands I enclose here under a trittico and two illustrations of originate them!
