Bigger Flies Better 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 whether youve flown many jets before or even if its 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 its still easy to take off, fly and land especially when equipped with the exclusive AS3X and optional-use SAFE Select technologies included with the BNF Basic version
