Controlling 3-wire PWM fan speed

Hello all,

I'm new to using arduino and new to the forums and I was hoping I could get some help on my project. I am trying to build a simple remote control hovercraft and control the fans with an arduino uno. My aim is to have both the lift and propulsion fan speeds controllable through an RC transmitter. I really have no idea where to even start for the code, though. I want to be able to push a stick on the transmitter forward and have the fan speed increase, push it back and the fan speed decrease.

I am using this fan:

Any advice you could give would be much appreciated, and any code would help me out a lot.

I'm really stuck here. I know the code should be fairly simple--just simply increase or decrease fan speed when the stick is moved. Please, any advice will help

Have a look at :

Project more complicated than yours, but remove unnecessary parts shouldn't be a problem

Thank you, magician. That helps a little bit. However, it seems almost too much for what I am trying to do. I want to just be able to read in values sent to the arduino from a receiver that is paired with the transmitter, scale them, and then control the fan speed based on those scaled values.

If I just wanted to modify the PWM of the fans, how would I do that? Like, for instance, if I could take in a "desired" fan speed from the transmitter, how can I output what I want the fan to do corresponding to what value I get from the transmitter?

It will give you an idea, in which direction to dig your local library and google. :)
