First, learn how to fly your cpv3 in a good solid hover. Practice someplace with a large smooth surface and no wind. Follow this:

I learned how to hover with a blade CP (pretty similar to your cpv3) using the above website. It takes a lot of patience and focus but with practice it will become second nature. And when you can handle the cpv3, you can handle just about anything.

Second, forget about that list you've compiled. Only two are even capable of going inverted, and they will be nearly impossible to learn that on. In fact, before you even get another heli you may want to consider investing in a sim if you don't already have one. This will go a long way in helping you learn while saving you money in repairs.

When you are ready to upgrade to a better heli, save up and make the investment in a trex 450 or something similar (there are some nice copies that are more affordable). The 450 size and belt driven tail will be MUCH MUCH MUCH more stable and easier to fly than anything you're considering above. It may seem like a lot of money up front and you may be tempted to work your way up but trust me, if you're sure this is a hobby you're going to stick with a nice 450 size is going to be cheaper in the long run.


The 4g3 can be a fun little heli for the experienced pilot, but I wouldn't recommend it for someone still learning the basics.
