Manufactured with super tight tolerances makes the SoloFlyer a very HIGH QUALITY rc heli unmatched by other cheap imitations. Featuring a fully proportional 2.4 Ghz radio with digital LCD screen and digital trim tabs (for easy in flight adjustments). The 2.4 Ghz radio systems are known to have much better reception than a standard F.M. radio and ensure a glitch free flight with double the range in addition to having super fast servo response times. This makes for a better RC experience. As a BONUS, the SoloFlyer comes with 2 Lipoly 110mah battery packs and a dual peak A/C charger, so that you can charge both batteries at one time. Each battery provides up to 15 minutes of run time. Includes a high quality metal Phillips screwdriver to replace main rotor blades if needed. One extra spare main blade set included as well as 4AA batteries for the controller, so there is nothing else needed to buy. All packed neatly inside our customer metal carrying case for easy transport.
