Larger Flies Much Better
The full-blown Viper was designed to provide fighter-jet appearances and performance along with the stability of a low-wing sport plane so more pilots might take pleasure in flying a jet. The E-flite® Viper 90mm EDF Jet design follows suit, both in its appearance and how it delivers the widest flight envelope possible — whether you've flown lots of jets before and even if it's your very first large-scale jet design. We scaled up the exceptionally popular Viper 70mm EDF to create the very first 90mm EDF powered and biggest jet from E-flite® yet! This larger version delivers the same excellent speed, vertical performance and aerobatic capabilities, plus it's still easy to remove, fly and land – especially when equipped with the unique AS3X® and optional-use SAFE® Select technologies consisted of with the BNF® Fundamental version. It's the best large-scale EDF choice for low-time and experienced 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 design of the popular jet yet! It's a scale jet that flies smoothly and manages like a sport plane — yet is also efficient in unbelievable aerobatics and top speeds! But what genuinely sets it apart is how easy it is to remove, fly, and land, that makes it the BEST choice for a very first large-scale jet design. Assembly is quick and simple, with no glue required. The light-weight, composite-reinforced EPO airframe is factory-finished in the now renowned Airplane Studio Style trim scheme from the popular 70mm design. And the eight factory-installed digital, metal-geared servos with ball-link equipped linkages, plus control surface areas with pinned hinges, deliver crisp and exact control at every speed. Functional features include flaps, LED landing and navigation lights, and electrical retracts with shock-absorbing, trailing-link struts on the nose and main gear so you can fly from yard and other surface areas with ease.

The BNF® Fundamental version consists of a 12-blade 90mm fan, powerful 6S-compatible brushless inrunner motor, and a 130-amp Bird™ Smart ESC that all interact 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 can level flight tops speeds approximately 120+ MPH and uses great vertical performance with SIX 4000mAh to 7000mAh batteries. It's also equipped with a factory-installed Spektrum™ AR637TA receiver featuring unique AS3X® and optional-use SAFE® Select technologies. When using suitable transmitters, the receiver and Smart ESC supply battery voltage, current, motor RPM and other telemetry information in real-time — along with optional-use motor reversing to shorten rollouts after landing and for other unique ground handling capabilities. An ARF Plus version is also readily available for pilots who choose to install their own choice of ducted fan system, motor and ESC. Either way, for low-time to experienced jet pilots this design delivers a large-scale EDF experience unlike any other!

Optional-use SAFE Select uses pitch and bank angle limitations along with automated self-leveling that can be switched on and off at the flip of a switch to make this a much easier to fly Viper! And if you don't want to enable the SAFE Select features, simply bind the receiver usually and just AS3X will be active.
