The CP and CP+ would be a little easier to fly than the CP Pro. But the CP Pro has a 3 in 1 so you could hook up a gyro if you wanted to. I would recommend the CP+ to start out with then get the CP Pro bell hiller system when you are ready. If you are using the wooden blades get plenty of extras and get plenty of spindles and mainshafts. Those where the main things that I had to get when I was learning on the CP Pro. Usually the bigger the helicopter the easier it is to learn on. I could have easily bought a T-Rex with all of my broken parts on the CP Pro, but there are plenty of alternative helicopters that are good for alot cheaper. The E-Sky series has a lot of good CP helicopters that are reasonably priced.
The CP+ Also has a 3in1 only diff between the cp+ and cp pro is the bell hiller on the pro and the hiller only on the cp+ to get the cp+ to bell-hiller it is about a 20-30 upgrade, the hiller is easier to learn on as it isnt as sensitive as the bell-hiller.
SO I say CP+ as it is less twitchy, can put a HH gyro in it, easy to go brushless and when you have the skill and confidence you can add the bell-hiller mod and really tear up the sky. And that is my .02
