Default Beginner needing to learn about servos

Hey everyone,

If you couldn't tell by the title, I am a newbie. I did a search and I didn't feel like wading through everything.

I am starting to get into R/C and electric planes. The whole process of plugging things together to make the plane move is beyond me at this point. Could someone explain some things to me?

The plastic top on the servo motor, what do those do?

How are you sure that the servo is turning the right way?

Are there servos that are no good?

Do Futaba transmitters work with JR recievers?

Do Futaba servos work with a JR reciever?

Where do crystals go?

I will think up some more questions as time goes along.

Thanks in advance!

Hey everyone,

Thats the servo output, you hook up what ever you want to move and they rotate in response to the sicks to move your control surface.

How are you sure that the servo is turning the right way?
Most radios have software or dip switches that reverse a servo, in the old days you just put the control linkage on the other side.
Are there servos that are no good?
Most modern servos are reliable, the key is to match the torque and speed ratings to the requirement of the airframe or whatever.

Do Futaba transmitters work with JR recievers?
In general, in North America, no.

Do Futaba servos work with a JR reciever?
Most modern servos are wired they same, you can pretty much use any brand servo with any brand reciever

Where do crystals go?
In the receiver, the transmitter should come with one
I will think up some more questions as time goes along.

Thanks in advance!

No problem but just an FYI, saying you did a search but didn't feel like reading the results isn't a good way to get alot of responses.

From a former medic my self. Reading is the fastest way to learn. Dennis

Drive out to Joe's Hobby Center in Farmington. They should be able to answer all of your questions and do so with "show and tell" capabilities.
Not really hard to get there from your home as it is all freeway.

I haven't been there for years but they were one of the best RC Hobby Shops in the country-----chances are that they still are.
Certainly beats the best understanding you could glean from the web alone.

Thanks Onewasp,

I've been looking at a good hobby shop to ask some questions, but lately I haven't found one that is really that good. I have newbie questions, and I don't want the guy being asked to look bored.

I will try to find them and go as soon as possible!

What I meant by "I didn't feel like reading" I typed in beginners into servos, and a whole bunch of stuff came up. All of it seemed that it wasn't what I was looking for, so I decided to post my own thread.

We all want to help. But tying that much information is hard to do. I type very slowly and with two fingers. You can call at my store. It's easier to talk. 270-7834004. Dennis

IMO There is only ONE stupid question, and that is the one you did not ask(thinking it was a stupid question), before going out doing something Stupid.

Just Like me trying to fly a RC 3D Heli without knowledge, without Simulator Training and without researching some of the info about how to start learning Heli RC Flying.
(And yes, I did buy a Simulator and a Simulator Controller )
