A rule of thumb to find well suited servos for you helicopter: | |||
'''As strong as necessary, as fast as possible.''' | '''As strong as necessary, as fast as possible.''' | ||
Torque should be at least 2-3 times the heli weight | |||
Torque should be at least 2-3 times the heli weight. Speed should be at least 0.1s/45° or even faster. In addition the servo should be very precise, have little backlash and a low deadband. And of course best would be if it is a digital servo and supports 200 Hz driving frequency. Also using a special heli servo which are specially made for maximum vibration resistance is a good choice. | |||
Note that all the speed is useless if the torque is not enough. In doubt when two servos of a series are only slightly different in speed and torque, normaly the more powerful is in advantage. | Note that all the speed is useless if the torque is not enough.

Anyhow ask the manufacturer of the servo if it can be used in combination with flybarless/gyro systems. Not all servos can handle the additional stress of getting control signals every few milliseconds. | Anyhow ask the manufacturer of the servo if it can be used in combination with flybarless/gyro systems.
