Like the Blade MCX the Evo Flight Mini Stinger has a proportional four channel radio. Four channel control means that pilots can fly the helicopter with four dimensions of freedom. The Evo Flight Mini Stinger can fly up/down, rotate left/right, pitch forwards/backwards, and bank left/right. With a four channel radio you can precisely control the Evo Flight Mini Stingers’ movement through all three dimensions. With a rotor size of 188mm (7.4”) and a length of 213mm (8.4”) this helicopter can easily fit in the palm of your hand.
The coaxial rotor design of the EVO Flight Mini Stinger provides this helicopter with great stability, and eliminates the need for a separate tail rotor to control yaw (rotation about the main rotor axis). The main rotors spin in opposite directions, canceling out rotor torque caused by their rotation. Coaxial RC helicopter are great for flying indoors, because of their stability and the precision control provided.
The Evo Flight Mini Stinger uses a tiny 1 cell lithium polymer battery for power. Unlike most micro RC helicopters, the battery is removable and interchangeable. Each cell provides 3.7 volts of power with a capacity of 110 mAh (Milli ampere hours). You charge the battery using the included transmitter, which runs off four “AA” alkaline batteries. A typical charge takes about 30 minutes and provides an average flight time of 6 to 8 minutes. Because the battery is interchangeable, we recommend that you purchase an extra so that you can use one while the other is charging.
