Hi, Ive got 4 servos in an enclosed space and after running for a while ive noticed that they are getting very hot. Is this normal for servos? I also have 4 voltage regulators (1 for each servo) with heatsinks and they are pretty hot too. One of the servos is constantly making a noise (like its just correcting itself). I know this will use more current and cause more heat but they seem to be getting way too hot.
