My servos are not on the website's servo list. Can I use them anyway?

The servo list on the website only is a collection of some servos' data. It does not say that if a servo is not on the list that you must not use it. If a servo is not on the list we simply did not test it ourselves or we could not find any data about it. Also we can't know any servo on the market. In fact the BEASTX flybarless devices are compatible to nearly any servo on the market. As a rule of thumb 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° 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 special heli servos which are designed 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. 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. Also it must be said that not all servos can be used at maximum frequency even if so it is told on the servo's data sheet. Depending on air temperature, voltage level and heli size it is possible that servos can not be driven at their limit.
