Similar to the full-scale ViperJet, the E-flite® UMX™ Viper 30mm EDF delivers fighter-jet looks and performance with low-wing prop-driven airplane handling so more pilots can enjoy flying a jet! It’s a scale EDF that flies smoothly and handles like a sport airplane - yet is also capable of incredible top speeds and aerobatics. But what truly sets it apart is how easy it is to hand-launch or take off, fly, and land, which makes it the class-leading choice for a wide variety of pilots. The lightweight, composite-reinforced airframe arrives factory assembled and nearly ready to fly right out of the box, plus it’s factory-finished in the now iconic Aircraft Studio Design trim scheme. A 4S-compatible power system delivers modern-day EDF performance to make it the highest-performance ultra-micro class jet model yet!
This model is equipped with Horizon Hobby and Spektrum exclusive AS3X (Artificial Stabilization – 3-aXis) and optional-use SAFE (Sensor Assisted Flight Envelope) Select technologies, and when SAFE Select is turned on using the mode switch (B on the Spektrum InterLink DX controller) it offers:
Pitch and Bank Angle Limits: These envelope limits keep the airplane from rolling or pitching upside down. They also prevent excessive climb or dive angles.
Automatic Self-Leveling: The airplane instantly returns to and holds level flight when the sticks are released and in the center position. It’s also helpful for keeping the wings level during takeoffs and landings.
