SERVO HS-40

great product

I had to replace both servos in a mini flying wing, the original servos were no longer made,. These work great and were easy to install. Also it was easy to adjust them in my Spectrum DX6E radio. I'm using them with a new Spectrum AR410 4 channel receiver, which has the benefit of having no antenna wire that can get damaged.

These lightweight Hi-Tech servos are the best that I have come across.

I liked the compactness. Nano servos pack the torque of the feather weight models.

This is a really small servo but with that it has no power at all. It is inexpensive so if you have something that requires movement without any torque these might do. Otherwise a waste of money.
