Larger Flies Better
The full-blown Viper was designed to provide fighter-jet looks and performance along with the stability of a low-wing sport plane so more pilots could take pleasure in flying a jet. The E-flite® Viper 90mm EDF Jet model does the same, both in its look and how it delivers the widest flight envelope possible — whether you've flown many jets before or even if it's your first large-scale jet model. We scaled up the incredibly popular Viper 70mm EDF to create the first 90mm EDF powered and biggest jet from E-flite® yet! This larger version delivers the same outstanding speed, vertical performance and aerobatic abilities, plus it's still simple to take off, fly and land. It's the ideal large-scale EDF option for low-time and knowledgeable jet pilots alike!

A Unique Large-Scale Jet Experience
The E-flite® Viper 90mm EDF is the Most intelligent, best handling, and easiest to fly large-scale model of the popular jet yet! It's a scale jet that flies efficiently and deals with like a sport plane — yet is also efficient in unbelievable aerobatics and leading speeds! But what truly sets it apart is how simple it is to take off, fly, and land, which makes it the very best option for a very first large-scale jet model. Assembly is quick and simple, without any glue required. The lightweight, composite-reinforced EPO airframe is factory-finished in the now iconic Airplane Studio Design trim scheme from the popular 70mm model. And the eight factory-installed digital, metal-geared servos with ball-link equipped linkages, plus control surface areas 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 turf and other surface areas with ease.

The BNF® Standard version includes a 12-blade 90mm fan, effective 6S-compatible brushless inrunner motor, and a 130-amp Bird™ Smart ESC that all work together with the skillfully optimized ducting to deliver an abundance of speed and thrust plus a turbine-like sound. With this power system, the Viper 90mm can level flight tops speeds as much as 120+ Miles Per Hour and offers 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 utilizing suitable transmitters, the receiver and Smart ESC supply battery voltage, current, motor RPM and other telemetry data in real-time — along with optional-use motor reversing to shorten rollouts after landing and for other special ground handling abilities. An ARF Plus version is also readily available for pilots who choose to install their own option of ducted fan unit, motor and ESC. Either way, for low-time to knowledgeable jet pilots this model delivers a large-scale EDF experience unlike any other!
