Understanding servo sizes
I've been away for a few years and things have changed a lot. We used to purchase our servos by size and torque. I need to purchase some new ones and the terminology leaves me lost. When they refer to a 15g is this torque, weight or what. I need servos for a .15 sized plane and these were suggested.
Thanks for your help.

I see a lot of servos sized by weight, 3.5g, 7g, 9g, 12g, they also give a torque rating 1.2kg-cm, 5kg-cm and so on. For a plane the size you are asking about, .15 glow power, you have tons of servo's to choose from. Analog, digital, plastic, korbonite, metal gear, plain, single bearing double bearing. You only limit is cost.
I have these in small foam planes to a 30 sized trainer, helicopters, gliders, glow and electric planes.

I have a set of these, they are not a low cost budget servo, but not way over the top either. They have worked well for me in helicopters and gliders. Tough, fast, accurate servo.

Servos have gone from only one to choose from, to so many you can go crazy trying to pick one.

Thanks for your input Buzz.
I started this RC thing back in the early 70's with a Kraft 2 channel brick. Been able to pretty much keep up with things until I took a breather a few years ago. Torque and dimensions were the main concerns with only a few option as you mentioned. Now it's like shopping for women's shoes, there is no end to it.
In the past when I needed help Heads Up RC has been a big help and their advice has been spot on. So I contacted them and they suggested this servo http://www.headsuphobby.com/Power-Up...ervo-H-240.htm
Hopefully they work out .
Thanks again for your advise.
