UMX Ultrix, BNF Basic, Spw. 342mm
Horizon # EFLU6450
The UMX™ Ultrix™ is an extremely versatile delta for relaxed sport flying, classic aerobatics, and even aggressive 3D, performing even better than its looks suggest. The brushless twin motors provide an incredible power-to-weight ratio with hovering capabilities and unlimited vertical climb. Differential thrust provides yaw control and the ability to fly advanced aerobatic maneuvers, including harriers, amazing flat spins, and more. The extremely durable EPP construction makes this model one of the toughest ultra-micro models ever. The Ultrix handles windy conditions well. The exclusive AS3X® (Artificial Stabilization - 3-aXis) technology works behind the scenes to counter the effects of wind and turbulence – making it feel like you're flying a larger aircraft. The optionally activatable SAFE® (Sensor Assisted Flight Envelope) Select technology makes it a breeze for inexperienced pilots to master the Ultrix, while its ultra-small size and lightweight construction allow flying almost anywhere. Experienced pilots can enjoy indoor flying in smaller gyms, while large soccer fields and model airfields are ideal for almost any pilot. The Ultrix comes factory-assembled and ready to fly within minutes of opening the box. Simply install a 1S 500mAh LiPo (EFLB5001S25) and bind it to a™ DSMX® / DSM2® compatible Spektrum transmitter! You can even attach the optional LED lighting kit (EFLU6455) to improve daytime visibility or fly at night.
