The new Firefox SR breaks new boundries in the indoor heli category. We have designed a single rotor helicopter that's super easy to fly and at the same time super agile! Includes a 2.4GHZ 4-channel radio system for complete control. The Firefox SR includes a built in micro gyro stabilization system to enhance its hovering abilities way beyond other micro helis. With the included 420mAh battery, the Firefox can get 10-13 minute flight times. Comes complete with an auto peak A/C wall charger for quick charges and a colored LED lighting system adding some cool visuals to all the fun.
