Salut, j'ai retrouve le post sur RCgroup de alexander. Ci joint L'url http://www.rcgroups.com/forums/showthread.php?t=575606 Et son comentaire.
For a perfect PiccoZ, play around the hinge axis on the main rotor should be zero, while beeing absolutely free to move around that same hinge. Easy to understand that this is nearly impossible to accomplisch in mass production. So most PiccoZ come with somewhat too much play to avoid that there is the slightest friction given variances in plastic schrinkage and assembly tolerances. For those who want to get the best results, there is a simple way of reducing the hinge play, altough if done the wrong way, it will make it fly worse. So, on your own risk (no warranty), you could try the following. First measure play by moving one blad tip up and down without bending. Take a metal rod of about 2mm diameter (not critical) and sharpen it to a tip like a pencil. Avoid to make it needle sharp or it will make holes in the plastic (that is not the purpose, see further) . You can use the tip of a small phillips screwdriver too. Locate on top side of the rotor, about 3-4 mm each side of the central hole along the hinge axis. Beneath that are hidden the molded plastic hinge pins. Put one finger on the underside of the rotor for support, and CAREFULLY but FIRMLY press with the pin on the top side (right above the hinge pin) to make a small dent in the plastic. Do the same the other side. These dents actually reduce the gap between the plastic of the rotor and the hinge pin, reducing play. Do this in small steps, and check each time if play has been reduced, and if more could be done. It's better to stop too early rather than too late. In the latter case, there will be friction and that is a realy not what we want. There may be a way back, but I never had to try I have done it a couple of times and it's actually not too difficult for a carefull and delicate modeller's hand. It's best when play is 'just a little bit'. Try it in case your PiccoZ does not has this 'solid' feel and you will be amazed. Once that done, you can check if blade tips (with stabilizer rotor at 90degrees to the vertical rotor axis) are at 90 degrees to that axis too. If not bent one end till it does. Last, check if incidence of one blade side equals that of the other side. If not, adjust one side at the root end by pressure (NOT at the tip) Some small strips of tape on one end or the other can further help to smoothen out things. I emphasise that this is at your own risk (if you screw it up), or satisfaction (if you succeed) a+ Enrique Iglesias Osuna -- No virus found in this outgoing message. Checked by AVG Free Edition.
