Tiny servos

Jul 16, 2005 3 Replies

A while back, I mentioned that I had purchased a U-Can-Do electric foam model plane. I had commented that I wasn't going to buy special servos for it, thinking that my five or so year old Hitec HS-80's would be small enough. I was wrong. Those things are gigantic compared to what is necessary.



Well, I broke down and followed Jim's advice and ordered some tiny servos (Cirrus CS-6.5). They just got here and I opened the box. These are truly tiny. In fact, they almost look like a joke item, to an old timer such as me.



I followed the instruction recommendations and ordered 9G or smaller (whatever that stands for - weight - I think) from Hobby People. I am a cheapskate most of the time, so I ordered their $9.99 (approximate) servos for this project. If they are not suitable, I'll just buy the right ones next time. But I am glad that I bought these anyway. I can think of a million applications for them. Especially, non R/C applications.



Neat.

Ted shuffled out of his cave and grunted these great (and sometimes not so great) words of knowledge:

They are quite small AND EXTREMELY powerful - you can get up to 50+ oz torque @4.8 volts. The price isn't that bad either - typically under $20 each.

Ed, you might want to research Blue Bird servos if you think you might like to order some. Some people have had problems with them.

Here's a good place to start:

Do a search in the "Radios" forum.

An alternative is the Hitec HS-55. They weigh 8 or 9 grams; I have a bunch of them, and none has ever failed.

Thanks for the tip, Jeff.
