Servo torque in kg/cm should be at least 2-3 times the heli weight (in kilogram). Speed should be at least 0.1s/45°. The faster the better. In addition the servo should be very precise, have little gear backlash and a low deadband. And of course it should be a digital servo that supports high frame rates (200Hz or more). Also using special heli servos which are designed for maximum vibration resistance is a good choice.<br /> | Servo torque in kg/cm should be at least 2-3 times the heli weight (in kilogram).
