Description
The full-scale viper was designed to offer fighter-jet looks and performance along with the stability of a low-wing sport airplane so more pilots could enjoy flying a jet. The e-flite viper 90mm edf jet model follows suit, both in its appearance and how it delivers the widest flight envelope possible â whether you've flown many jets before or even if it's your first large-scale jet model. We scaled up the extremely popular viper 70mm edf to create the first 90mm edf powered and largest jet from e-flite yet! this larger version delivers the same excellent speed, vertical performance and aerobatic capabilities, plus it's still easy to take off, fly and land â especially when equipped with the exclusive as3x and optional-use safe select technologies included with the bnf basic version. It's the perfect large-scale edf choice for low-time and experienced jet pilots alike!
The e-flite viper 90mm edf jet is the smartest, best handling, and easiest to fly large-scale model of the popular jet yet! it's a scale jet that flies smoothly and handles like a sport airplane â yet is also capable of incredible aerobatics and top speeds! but what truly sets it apart is how easy it is to take off, fly, and land, which makes it the best choice for a first large-scale jet model. Assembly is fast and simple, with no glue required. The lightweight, composite-reinforced epo airframe is factory-finished in the now iconic aircraft 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 surfaces with pinned hinges, deliver crisp and precise control at every speed. Functional features include flaps, led landing and navigation lights, and electric retracts with shock-absorbing, trailing-link struts on the nose and main gear so you can fly from grass and other surfaces with ease
The bnf basic version includes a 12-blade 90mm fan, powerful 6s-compatible brushless inrunner motor, and a 130-amp avian smart esc that all work together with the expertly optimized ducting to deliver an abundance of speed and thrust plus a turbine-like sound. With this power system, the viper 90mm is capable of level flight tops speeds up to 120+ mph and offers great vertical performance with 6s 4000mah to 7000mah batteries. It's also equipped with a factory-installed spektrum ar637ta receiver featuring exclusive as3x and optional-use safe select technologies. When using compatible transmitters, the receiver and smart esc supply battery voltage, current, motor rpm and other telemetry data in real-time â along with optional-use motor reversing to shorten rollouts after landing and for other special ground handling capabilities. An arf plus version is also available for pilots who prefer to install their own choice of ducted fan unit, motor and esc. Either way, for low-time to experienced jet pilots this model delivers a large-scale edf experience unlike any other!
exclusive technologies
This large-scale viper model is equipped with exclusive spektrum as3x and safe select technologies. As3x works behind the scenes to smooth out the effects of wind and turbulence to deliver a locked-in feel that makes it seem like you're flying an even larger airplane. Optional-use safe select offers pitch and bank angle limits along with automatic self-leveling that can be turned on and off at the flip of a switch to make this an easier to fly viper! and if you don't want to enable the safe select features, simply bind the receiver normally and only as3x will be active
smart technology
The exclusive spektrum avian smart esc provides a variety of real-time power system related telemetry data including motor rpm, current draw, overall flight battery voltage and more via compatible smart receivers (including the ar637ta installed in the bnf basic version) and spektrum airware equipped transmitters (including the dx6e, dx8e, dx6 g2/3, dx8 g2, dx9, nx6, 8 and 10, ix12, ix20, and others) while you fly. Plus, optional-use motor reversing can help shorten rollout after landing and offers other special ground handling capabilities (7+ channel transmitter required for reversing)
high-performance edf
The 12-blade 90mm fan, high-power brushless inrunner motor and 130-amp esc combine with your 6s 4000 â7000mah 30+c lipo battery to deliver great vertical performance and a fantastic speed range with virtually instantaneous throttle response. There's even room to fit two 6s 3200 â5000mah batteries so you can run them in parallel to achieve class-leading performance and flight times
functional features
Factory-installed led navigation and landing lights, nose gear door and flaps are functional features that take your experience to another level
capable gear
Shock-absorbing, trailing link struts on the nose and main gear soak up the bumps of rough surfaces including grass and make it possible to fly from a wider variety of fields. The reliable electric retracts are equipped with durable metal components, and the steerable nose wheel plus wide-spaced main gear offers excellent ground handling
unmatched capability
The viper design offers incredible handling across a wide speed range and flight envelope. From slower-than-expected landings and low-speed passes to 120+ mph high-speed flybys, the airframe and power system combine to deliver unbelievable performance and aerobatic capability so you can perform giant loops, rolls, endless knife edge flight, snaps, tumbles and other maneuvers almost effortlessly
durable precision
The composite-reinforced epo airframe is lightweight yet durable. And the eight factory-installed digital, metal-geared servos with ball-link equipped linkages, plus control surfaces with pinned hinges, deliver crisp and precise control at every speed
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! the stabs plus the two-piece wing with hands-free connections bolt into place and can easily be removed for convenient storage and transport. Plus it's factory-finished in an exclusive and unique high-visibility trim scheme by aircraft studio design
