Hitec/RCD HS-40 Economy Nano Servo

In my experience, the Hitec servos have been more reliable and longer-lasting than some of the cheaper alternatives, and since a servo failure can easily destroy an airplane, I'm gradually replacing my Hxt-500s and similar servos with HS-40s. The HS-40s that I've weighed are 5.1 gm each, including wire and servo arm. I typically use them on tail surfaces on 50W aerobatic aircraft, and I'd be comfortable using one of these to drive one aileron on a 50W airplane or both ailerons on a 25W airplane.

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.

great product

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

hitech is still has some of the best values on the market today. This servo is small and compact with good solid torque for mini aircraft and other small applications where space and weight are a concern.

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.

Got this for a component for a Christmas present. Great value for how much it costs. Would recommend it to someone who was looking for a component like this!
