Big,
First of all, welcome to RCU. It really is a terrific place for Beginners, and for all us "know-it-alls".

I'm kidding. When everyone seems to ignore what you're looking to do and recommends taking bigger steps, it really is because we believe it's the better choice. And I'm usually right there with them saying DON'T get a 2 channel electric plane. More often than not, they barely fly, if they fly at all.

However, I have read about a couple guys that have bought inexpensive little 2 channels and loved them, so for the price maybe it would be a good choice for you.

And yes, you've pretty much figured out how the controls will work. Those two channel usually have two motors, so climbing is performed by adding throttle. Steering is done by lower throttle on one engine than the other.

Whatever you decide to do good luck, and above all, have fun!
