i would also recommend the cx2.. although the cp and the t-rex are better suited to fly acrobatics and outside, the cx2 is still capable of some entry level high speed manuevers.. with some simple adjustments and parts, you can make the cx2 aggressive enough to still be enjoyable later down the road.. if its not too windy you can alsy fly it outside. but learning to fly the heil "nose in" or facing towards you can be a feat on its own.. and from my experience with planes, its more fun to learn the basics and try to push the limits with what you have, then to try to learn on something too big for you.. the cool thing is that with the cx2 when you get bored, you can attach a magnet to an installed 5th servo on the bottom later, and pickup random stuff.. so in my opinion i recommend the cx2.. sure you can also learn on the cp as many have, it really all depends on if you have enough money to buy the parts to learn.. sadly, less "fun" also means less broken parts.. but the cx2 does go pretty fast when adjusted, and you can pull off some sweet manuevers.. check out the videos on youtube and here to see what they can do..good luck and enjoy
