My servos are getting warm/hot, is this normal?

Similar to a tail gyro a flybarless system is constantly working and correcting. So the servos are moving much more frequently than if they're controlled manually. Additionally the servos are usually driven with higher frequency, which means the system gives commands to the servos more often than usually (which will improve performance drastically). And because of the abolition of mixing levers and the support of the auxiliary rotor plane the servos have to resist higher forces in flight. This results to a higher power consumption and a stronger heat generation which usually is not critical. However under adverse conditions this can reach a critical range (e.g. at very high air temperatures or even if the servos are installed near other heat sources such as electric motors). In this case try reducing the driving frequency and/or the input voltage.
