Hi!

I am a complete newbie on the RC World, and I am looking build an application that could use some material from the RC world.

I need a needle valve, just like the ones that you use on your engines to fine tune them. The problem is that I need a valve than can some how be controled by some electric/electronic circuit.

Is there any valves like this on the RC world, perhaps any valve that can be adjusted by the controller while the plane is up on the skies?

If there is something like this, where can I buy it online?

Sorry if this is a stupid questioin

Thank you all
