Metal gear replacement servos to replace OEM servos in HobbyKing RC model aircraft. Two sets purchased.So far, these servos working well in two airplanes where the OEM plastic geared servos had stripped teeth. These Sunfounder servos are a millimeter or so larger than the HK ones and have a better quality more robust feel. They operate the same as the HK ones.Knocked one star off for the servo horns provided, which are too thin and have very small holes at close centres, suggesting they are from less robust plastic geared servos. The splines don't match the HK servos so had go with using these.These metal geared servos deserve much better horns.

This is a really nice servo, very smooth and the precision is excellent. I did notice one peculiarity, however. Most analog servos will not "hold" their position when you stop the PWM signal. At least they won't resist you turning them. These servos hold their position even after the PWM signal is switched off. In order to completely prevent them from holding a position under power, you need to actually cut the power to the servo, otherwise it will continue being locked to the last position while actively resisting any manual turning and will make a very faint humming noise. So this was an interesting observation. For those who are concerned about power consumption, be aware and modify your circuits accordingly. With that in mind, it's an excellent servo
