I am a new owner of the Blade CP Pro. My recommendation is to go for the the Blade CX if you are looking for easy to learn on. I bought the CP Pro because it had all the bells and whistles, and I thought it would be easy to learn on...so far, I have made a great effort at learning, but have put twice the original cost into it in replacement parts from my less than spectacular landings brought on by poor piloting or gusts of wind. I am told that the CX is much easier to start with and was told after I had already totalled my CP Pro, that I had chosen one of the hardest helis to learn on.
I do not know anything about the helimax, but was told that anything with a single main rotor and a tail rotor was tough to learn on. I was told that it is better to learn on something with twin main rotors and no tail rotor if you are going to go with the small electrics.
Heck, after I had totalled my Blade CP, the guy at the shop told me it would probably be easier to learn on one of the bigger nitro versions...
Hope this helps.
If you buy one or the other of the models you are looking at, make certain to pick up spare rotor blades (both the main and tail rotors), the training wheels are a must, and a spare set of landing skids can't hurt (I've gone through a few of them), a spare spindle, and a spare set of set pins for the rotor hub (they shear easily as they are designed to if your rotor impacts the ground).
