Adam,
Yes currently own 4 collective pitch helis. One if them is a Chinook (still building it) that each rotor is 3 ft across.
The big advantage of collective pitch is the ability to do aerobatics, as a result they are far less stable and much more maneuverable aka harder to fly.
Is the fixed pitch heli you bought like the one I brought to SELEM a few years ago? In other words a counter rotating dual rotor design (one rotor above the other)? If so, they don't fliy anything like a collective pitch heli. They are more of a hovering machine that you can coax to move in certain directions. Great for beginners but don't really teach you how to fly a helicopter. Many people buy these, master them, then step up to a collective pitch and crash getting frustrated buying tons of replacement parts and give up. I'm not saying that you can't do it, I just want you to know what your buying and what to expect. They are tricky machines.
Unless you have a simulator to practice on or have someone to teach you I would not recommend jumping into collective pitch. A simulator will teach you everything you need to know and crash as many times as you want without costing more. There are even free simulators out there, just make sure if you go that route you get a controller to plug into the computer. Without it you won't learn a thing.
I will be bringing my simulator with me to SELEM if you want to try a collective pitch heli before you buy anything. I'm also going to bring at least one of my new obsessions.
Quadcopters!
The big one is fully autonomous and has a GoPro mounted on it. Don't know that I will bring it, but definitely one of the smaller ones.
