Heres some info on the 3DMP (mein translation ist nicht so gut!)
The Three de MP (modular Powered) a complete new development in the 50er size with a Rotordurchmesser of 1,35m and a take-off weight of ca. is. 3kg. A peculiarity is enabled include the modular construction, that it both versions with a head mechanics that all components up to the drive and to fly an electro and/or Verbrenner module, that can be exchanged in minute fast. My concern was it a mechanics in this sizes class to conceive, lived comes out that is carried out qualitatively high-value and like of Henseleit Helicopters without additional upgrades. At the same time I had the ambition a sport device to create that more yet simpler and maintenance friendlier is constructed, than all my previous constructions. I have all construction steps even repeatedly through lamp and again and again in question placed to optimize around it yet further. Simultaneously this helicopter places got into mine into the electro scene there. He who knows me, knows that I until short time ago yet excluding the Verbrennerfraktion listened to. The reason for that was not permitted to stand the not satisfying rechargeable battery technology, that it to fly kraftzehrende maneuver without after few minutes again at the ground. Through the LiPo rechargeable batteries, all changed within shortest time and becomes to make to create and to show me caused now also a suitable helicopter, that it now possible its to begin with an E-Hubi against each Verbrenner without at the same time Leistungsabstriche. The 50er size appears me at present most meaningfully for the electro flight (seen of the littler hall flyers) because the amount of the rechargeable batteries holds itself yet in boundary. Through an optimal voting, it is arrive me flight characteristics as well as to reach in a larger Heli. To master straight line excursion characteristics in high speeds and the fortune large-area art flight without at the same time the 3D capacities is to be restricted a certain sign for the efficiency a system. In addition the Rotorkreisflächenbelastung may not exceed a certain measure, what one reaches in spite of stable method of building only through leaving out of superfluous parts. Compact and the MP clearly became and lets take apart will use itself it in shortest time into all components what for people with little time for repairing an important aspect its around the precious hours better for flying to can. As comes rotated naturally again my MFS-head (Moving Flybar system) to the use whereby the technical execution became in contrast the NT for the little Heli abgespeckt and Gewichtsoptimiert. It emerged take apart lets itself a stuck system that in minutes completely and fixes with only a screw everything. The paddle pole is led worry with a 12mm ball in a Delrinbuchse where little Einfräsungen for the centering in the middle and the alignment of the paddles. The Mischhebelanlenkung of the paddle pole passes to raise obliquely by the Hillerstabilisierung in spite of large bark-share. Different configurations are possible. The Heckrotorblattgriffe out of Alu are equipped equipped respectively with two radial warehouse and a pressure warehouse, as well as with Propellermomentgewichten to minimize around the Servokräfte. The single stage tooth wheel transmission is standard 20° schrägverzahnt and with module 1 so strongly displayed, that it all drives easily verkraftet. The head advantage lies are in the soft course of an oblique dovetailing, through it that permanently 2 of teeth simultaneously in the intervention and takes place a soft rolling off of the tooth flanks. The axial powers appearing through it are minimal and are received without problems by the motors warehouses. The Carbonheckrohr is with 25mm diameter in the 50er class extraordinary and offers next to better visibility an enormous stability as well as sufficiently place for the stern strap. The Chassisoberteil is out of two Carbonplatten and two out of the full milled Aluleisten with the corresponding warehouse seat and reinforcement thread as well as the stern tube stop put together. The warehouse cathedral receives two ball bearings and serves as a reinforcement for all three Taumelscheiben-servos as well as the Heckservos. With three screws, he can be mounted on the upper Chassis-verbindungsleiste. In the reason disk, a third 12mm warehouse is incorporated so that the hollow Rotorwelle is stored threefold and gives an enormous Steifigkeit to the total construction. Simultaneously the large 12mm warehouse receives game free the axial powers. At the same time the Rotorwelle is equipped is stuck has that at the lower end with a six edge into a gehärtete 12mm neutral bushing the one six angular Aussparung and establishes therefore form conclusive communication. How in the Rotorkopf, a screw holds screwed becomes also that axially at the forehead area of the Rotorwelle, all together. The neutral hub can be mounted into both directions so that one can select the Rotordrehrichtung in the electro version freely. Also the Heckrotor as well as the Anlenkhebel can be mounted beidseitig. Whether the Heckrotor should stand in the car rotation mitdrehen or, is freely eligible. I naturally again so formed the GfK hood that it closely surrounds the mechanics and produces only very slight Luftwiederstand. It removes herself optically through concave side walls and an easily angular lines leadership of my other hoods. A paragraph on the underside improves at the same time in addition the visibility and situation recognition and enables an inspection of the fuel state during the flight. The Verbrennermodul is constructed out of two Carbonplatten with motor carriers and the Kufen. The tank is pushed simply of behind between the disks and sits exactly in the focal point so that during the total flight no Lastigkeitsänderung enters. The visibility of the abundance state in the flight is given. Silencer let itself selectively on conventional manner on the side of mount alternatively gives or it a silencer that before the blower layer completely under the hood sits and lends the helicopter therefore a perfectly Aerodynamik and optics. A little disadvantage is there that to the candles change in addition the two exhaust reinforcement screw must be solved. My experience showed however that this is in correctly adjusted motors at most 1 once in the year the case. A Schottwand out of foam material holds off the hood and schottet simultaneously the warmth air of the muffler of the mechanics. The receiver rechargeable battery is attached movably on a Carbonstab and can pushed therefore to the attitude of the correct focal point situation into the corresponding position and become arretiert. The coupling bell has a warehouse cover with fine thread and is stored so beidseitig of the Fliehgewichtes. Through it it was possible that otherwise too little Ritzel to position in spite of the 9,5mm standard crank shaft of the OS of 50 motors directly at the crank shafts warehouse and to minimize therefore the load. Further a low building height of the coupling unit arises through it. That extended is unscrewed Fliehgewicht with the mounted coupling bell to the crank shaft. Based on the overheating problematic nature of the 50er motors the MP was equipped standard with a 69mm Alulüfterrad and has therefore the cooling of a from growth 60er machine. The electro module consists of an extremely distortion stiff Carbonchassis with a rechargeable battery room of 60x60x350mm and offers therefore sufficient place and Crashschutz for most LiPo or NiCd rechargeable batteries. The rechargeable battery becomes stacked pushed in of behind in that and so positioned that the focal point agrees. The E-motor is secured with a support ring on the motor carrier disk. The Befestigungsbohrungen so are formed that all current E-motors can be used. Through solve lets of 4 screws the total disk itself horizontally shift and permits a very simple and comfortable attitude the tooth flanks game. How the NT also the MP became sets a Fun-Heli to fly that through the possibility both electrically and also as a Verbrenner in the more bargain 50er class new standards. The reached flight behavior in this size surprised me even and places a handy alternative or also expansion to the large class there. To be able to fly the possibility now also electrically without achievement losses almost before the front door opened totally new telescopes in our pretty hobby.
