  • Atom 550 Ultimate


    The 550 Ultimate is the consistent further development of the 6HV Ultimate. The details make the model maintenance- and assembly-friendly or are for a better flight-performance. The 550U has got a third bearing block and the screws of the arm links are M4 diameter. Aluminium brackets are mounted into the carbon side frames so the assembly of the servos is fast and easy and the ESC got his own mount. Some fixing points for the wires are milled into the new two-part side frames. This reduces the cost in case of an crash and makes the helicopter easy to fix. The tail is widely used from the 7HV Ultimate and got an aluminium tail control arm, a 6mm tail shaft, reinforced tail blade grips and a stainless tail center hub. The most distinctive features are the new canopy leant to the design of the Warp360 and the new 25mm tail boom. The automatic belt tensioner first used in the 7HV is also used in the 550 Ultimate. Much more details like the notches for the velcro tapes, the head button, the canopy quick-releases, a new motor mount, the cf tail control rod and a new high-quality, helical delrin main gear make a perfect overall package. Get inspired by the all new 550U design!
