160+ mph and 6+ minute flights are just right for many of our customers.  This system is our most simple to operate and economical to own and it definitely outperforms the glow powered D/F systems that it was designed to replace.  The simplicity and value considerations of a 10s operation are maximized with the EVF10s.  The latest Thunder Power battery technology also enhances the EVF performance, this makes grassfield operation that much better.  One 10S charger will allow 45 minute cycle times at the field.  This power combination is an excellent choice for the Electra Jet, Sabre and a drop-in replacement of the early DF powered Maverick, Ultra Viper, and Aggressor III.
