Servo Programming

Not sure if I have more of a programming question or Electronics question.

I would like to know how to control my servo such that it spins continuously in one direction; is that possible?

I have an analog servo.

It depends. If it's a "true" servo then no; if it's modified (or modifiable) to be a so-called "continuous" servo, then yes.

I guess what I really want is a motor to play around with something that resembles a Helicopter.

Thanks for the reply.

A continuous rotation servo could be used in a non-flying toy helicopter to make the rotors move slowly. A small DC motor would probably be more suitable. Dismantled servos can be a cheap source of small DC motors!

A flying helicopter needs a powerful high speed motor.
