Hitec/RCD HS-40 Economy Nano Servo

紙袋で送られてきたのだが、明らかに外箱が潰れ全周にわたってサーボ収納部分に割れ。 明らかに外力がかかっているのでこれから返金対応してもらう。 どうでもいいものをしっかりとした箱で送ってくるのに、こういった精密機器は適当だなんて、教育どうなってんの? 返品したものが、再度売り物として利用されないよう願うばかりです。 （いくつか他にも別で注文したんだけど、紙袋で送られてきたのは全部幾分か潰れている。返金か交換か悩み中）

The size alone is impressive. Mg996R next to the sg9p next to the Ultra small HS40. They sent me a standoff spacer measuring tool and some candy. I plan on these baby servo's controlling the direction of my picam.

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.

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