With the UMX Viper 30mm EDF, Voltmaster adds an impressive new ultra-micro jet to its lineup. Derived from the extremely popular 64mm, 70mm, and 90mm versions, this model delivers a jet flying experience that sets new standards in its class.
Equipped with a powerful 30mm EDF unit, a 4S-compatible outrunner motor, and advanced onboard electronics, the UMX Viper offers precise handling, excellent stability, and outstanding aerobatic performance. Exclusive AS3X technology ensures a smooth, locked-in flight feel even in less-than-perfect conditions, while optional SAFE Select provides additional flight envelope protection for increased confidence.
Thanks to the Bind-N-Fly configuration, the aircraft is nearly ready to fly straight out of the box. With the landing gear installed, smooth-surface takeoffs and landings are easy; alternatively, the gear can be removed for increased performance and hand launches. Functional LED lighting, an iconic design, and a flying weight under 250 grams complete this compact yet highly capable jet.
The UMX Viper 30mm EDF is the perfect choice for pilots with some experience who are looking for a powerful, everyday EDF jet in a small and convenient format.
