Frequently Asked Questions
- Is the E-flite Viper 70mm EDF Jet suitable for beginners? — The Viper 70mm is classified as Skill Level 3 and is not recommended as a first RC aircraft or even as a next step after a basic trainer for low-time pilots. You should have prior experience flying simpler EDF models such as the Habu SS 50mm or 70mm, F-15 Eagle 64mm, or higher-performance sport models like the V900 and V1200 before attempting to fly the Viper 70mm. The BNF Basic version does include AS3X and optional SAFE Select technologies which make it easier to fly than PNP equivalents, but these are enhancements to a high-performance aircraft rather than beginner safety features.
- What battery does the Viper 70mm EDF require? — This model is compatible with 6S LiPo batteries in the 3200mAh to 4000mAh capacity range, with a minimum discharge rating of 30+C. The manufacturer recommends 22.2V (6S) LiPo packs with EC5 or IC5 connectors. Popular 6S 3200mAh to 4000mAh 30+C batteries deliver excellent performance and realistic flight times, with the higher capacity 4000mAh packs providing extended air time for longer flying sessions at UK RC clubs and flying sites.
- What makes the Viper 70mm different from other EDF jets in its class? — The Viper 70mm stands out through its combination of excellent vertical performance from the upgraded 1900Kv motor and 85-amp ESC, optional thrust reversing capability for advanced ground handling, fully-functional flaps for improved slow-flight characteristics, and the inclusion of both AS3X stabilisation and optional SAFE Select flight envelope protection. The updated shock-absorbing struts and softer tyres specifically address the challenges of landing on hard UK surfaces like concrete and tarmac, whilst the no-glue assembly design and factory-finished composite-reinforced EPO construction mean you're ready to fly within an hour.
- Can I use this with a 7 or 8-channel transmitter? — Yes, the Viper 70mm's Spektrum AR631 receiver supports 6–8+ channel Spektrum DSMX/DSM2 compatible transmitters. If you have a 7–8+ channel transmitter, you'll unlock the optional-use thrust reversing feature, which helps shorten rollout after landing and enables other specialised ground handling capabilities that aren't available with 6-channel systems.
- How fast does the Viper 70mm fly? — With a popular 6S 3200mAh to 4000mAh 30+C battery, the Viper 70mm is capable of level flight top speeds exceeding 120 MPH, with nearly unlimited vertical performance. This represents approximately 10% more speed than previous versions, thanks to the upgraded 1900Kv motor and 85-amp Smart Lite ESC.
- What is the difference between BNF Basic and other versions? — BNF (Bind-N-Fly) Basic means the aircraft comes with all electronics factory-installed including the motor, ESC, receiver and servos, but you need to supply your own compatible Spektrum transmitter, battery and charger. This makes it ideal if you already own a Spektrum radio system and want to minimise assembly time whilst maximising flying time.
