the affordable electric helicopter revolution was started by the GWS
mini dragonfly. For the first time, you can get an RTF electric
helicopter for the same price as regular park flyers. We sold mini-dragonflys
by the truck loads even though they were extremely difficult to fly
(much more so than the bigger helis).
Today's electric helis with
brushless motors and lipo batteries provide a level of performance that
equals their glow counterparts with much less fuss. No wonder this is
the fastest growing part of RC.
