Number one pick for ultra light applications, these Futaba micro digital servos are perfect for the FireFly 2.0 or any other light weight application. These pack a punch with an amazing 1.5 kg-cm of torque for a servo under 7.8 grams. Sure it will add an additional weight of 2 grams to the FireFly glider, but with the adequate power of its torque, this will be a perfect micro servo for the slopes on a single cell lip battery.
Of course with stats as these, comes a price not so friendly for most. These Futaba micro servos will cost roughly $16 a piece.
Ideal for electric planes and small electric helis
