Bigger Flies Better
The major Viper was developed to provide fighter-jet looks and performance along with 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 design does the same, both in its look and how it delivers the best flight envelope possible — whether you've flown numerous jets before and even if it's your very first massive jet design.

This bigger variation delivers the same outstanding speed, vertical performance and aerobatic capabilities, plus it's still simple to take off, fly and land – specifically when equipped with the unique AS3X® and optional-use SAFE® Select technologies included with the BNF® Standard variation. It's the perfect massive EDF option for low-time and knowledgeable jet pilots alike!
