Overview

The Viper 70mm EDF offers smooth, sport airplane-like handling plus incredible performance and aerobatic capability that makes it the perfect choice for experienced and first-time jet pilots alike. At its core is a 6S-compatible brushless motor and 70-amp ESC that are matched to a 12-blade fan to deliver an abundance of speed, thrust and a turbine-like sound. Functional, factory-installed flaps and electric retracts are included to provide the best jet experience and the widest flight envelope possible. Assembly is fast and simple with a one-piece wing and stabilizers that bolt into place–no glue required. The detailed cockpit is integrated with the large top-mounted hatch that makes flight battery access as easy and convenient as possible. Digital, metal-geared servos and ball-link equipped linkages provide precise control, and the lightweight yet strong EPO airframe adds to the durability and precision. But what truly sets the Viper 70mm EDF apart, and helps make it the BEST choice for a first jet model, is how easy it is to take off, fly and land. It’s a scale jet that flies smooth and handles like a sport airplane, with stability that makes it feel rock-solid so all you have to do to make your jet pilot dreams come true is advance the throttle.

 

High-Power EDF

The 12-blade 70mm fan combined with the high-RPM brushless motor, 70-amp ESC and a 6S 3200-4000mAh LiPo battery delivers nearly unlimited vertical performance and an incredible speed range with virtually instantaneous throttle response. But what makes the experience truly rewarding is the amazing sound produced by the power system—it’s almost like a real turbine.

 

Functional Flaps

The factory-installed, fully-functional flaps offer improved slow-flight capability and performance while also making it possible to take off and land in shorter distances and at slower speeds.

 

Electric Retracts

The steerable nose wheel and wide-spaced main gear feature reliable electric retract units equipped with durable metal components and sprung wire struts for operation from a variety of surfaces including paved runways and even grass.

 

Durable Precision

installed digital, metal-geared servos with ball-link equipped linkages deliver crisp and precise control at every speed.

 

Amazing Performance

The Viper design offers incredible handling across a wide speed range and flight envelope. From slower-than-expected landings and low-speed passes to 100+ MPH high-speed flybys, the airframe and power system combine to deliver unbelievable performance and aerobatic capability so you can perform smooth rolls, giant loops, knife edge flight and other maneuvers almost effortlessly.

 

Easy Assembly

No glue is required for assembly, and you can have the Viper ready to fly in less time than it takes to charge a battery. Plus it’s factory-finished in an exclusive and unique, highly-visible trim scheme by Aircraft Studio Design.

 

Bind-N-Fly Completion Level Advantage

Already own a Spektrum™ transmitter? Bind-N-Fly (BNF) aircraft make getting into the air quickly and with the best control experience possible easier than ever. They come out of the box with the power system, servos and a Spektrum 2.4GHz receiver installed so all you need to do is bind the receiver to a compatible transmitter, finish any final assembly, and fly!

This Bind-N-Fly Basic model is equipped with a Spektrum 2.4GHz DSMX® receiver featuring AS3X (Artificial Stabilization–3-aXis) technology that works behind the scenes to smooth out the effects of wind and turbulence. The result is a heightened sense of stability and precision that makes you feel like you’re flying a much larger, expertly tuned aircraft.

If this is your first model of its type, or you want an extra margin of safety while familiarizing yourself with the airplane, you can enable the optional-use SAFE® Select flight envelope protection technology built into the receiver. No programming is required. Simply change up the binding sequence as directed in the manual.

 

With SAFE Select enabled, you get:

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/launches and landings.

Easy Switch Assignment—No Complex Programming Required

• The simple procedure for assigning a transmitter switch to turn SAFE Select features on and off doesn’t require any complex programming and takes just a few seconds.

If you don’t want to enable the SAFE Select features, just bind the receiver normally and it will function like a standard AS3X receiver.
