Bigger Flies Much Better
The full-blown Viper was developed to offer fighter-jet appearances and performance in addition to the stability of a low-wing sport airplane so more pilots might take pleasure in flying a jet. The E-flite® Viper 90mm EDF Jet model follows suit, both in its appearance and how it provides the largest flight envelope possible — whether you've flown numerous jets before or even if it's your first large-scale jet model. We scaled up the very popular Viper 70mm EDF to develop the first 90mm EDF powered and biggest jet from E-flite® yet! This bigger variation provides the very same excellent speed, vertical performance and aerobatic abilities, plus it's still simple to take off, fly and land – particularly when equipped with the unique AS3X® and optional-use SAFE® Select innovations consisted of with the BNF® Standard variation. It's the perfect large-scale EDF option for low-time and skilled jet pilots alike!

A Unique Massive Jet Experience
The E-flite® Viper 90mm EDF Jet is the Most intelligent, finest handling, and most convenient to fly large-scale model of the popular jet yet! It's a scale jet that flies smoothly and deals with like a sport airplane — yet is also capable of amazing aerobatics and top speeds! However what genuinely sets it apart is how simple it is to take off, fly, and land, that makes it the BEST option for a very first large-scale jet model. Assembly is quick and easy, with no glue needed. The lightweight, composite-reinforced EPO airframe is factory-finished in the now iconic Airplane Studio Design trim plan from the popular 70mm model. And the eight factory-installed digital, metal-geared servos with ball-link equipped linkages, plus control surfaces with pinned hinges, deliver crisp and accurate control at every speed. Practical features consist of flaps, LED landing and navigation lights, and electrical retracts with shock-absorbing, trailing-link struts on the nose and primary equipment so you can fly from lawn and other surfaces with ease.

The BNF® Standard variation consists of a 12-blade 90mm fan, powerful 6S-compatible brushless inrunner motor, and a 130-amp Bird™ Smart ESC that all work together with the expertly optimized ducting to deliver an abundance of speed and thrust plus a turbine-like noise. With this power system, the Viper 90mm is capable of level flight tops speeds as much as 120+ Miles Per Hour and provides fantastic vertical performance with SIX 4000mAh to 7000mAh batteries. It's also equipped with a factory-installed Spektrum™ AR637TA receiver including unique AS3X® and optional-use SAFE® Select innovations. When using suitable transmitters, the receiver and Smart ESC supply battery voltage, current, motor RPM and other telemetry information in real-time — in addition to optional-use motor reversing to shorten rollouts after landing and for other special ground dealing with abilities. An ARF Plus variation is also available for pilots who choose to install their own option of ducted fan system, motor and ESC. In either case, for low-time to skilled jet pilots this model provides a massive EDF experience unlike any other!
