Well...the jump from a cx2 to a raptor 50 is a pretty big one. You might be better off investing your money in a good sim, teaching yourself to fly with that, then moving to the raptor when you can fly every heli in the sim. Every heli feels different, and in order to get myself prepared to be able to adjust to a heli with a quickness, I have practiced switching between the helis on my sim. I fly one for a few minutes, then switch to one that has totally different behavior and leave the trim settings for the other heli, then bring the new one in the air and try to get it trimmed as quick as possible. This has helped me alot. a cx2 pretty much hovers itself, while a raptor will take a little more input and attention. I say, get a sim, learn to fly on it, then get the raptor and study EVERYTHING you can find about it for setup and adjustment, get training gear, and go give it a try. Just take it easy the first few times till you get it trimmed, then go from there. The sim will be your friend for a while, cause you can use it to learn new moves without risking your heli. But this is just MY opinion. The choice of course, is up to you. Whatever you decide, good luck and happy flying! Peace.
