You could very easily get about a million different responses to this question.

I think ircheli picked some good ones. If you are more for just having it to play with then Blade mCX. If you want something to test the waters to see if you want to spend the cash for the real deal I would start with the older brother blade cx2 . It is coaxial so not difficult to learn on to get your bearings.

I personally learned on the blade cx, then went to the axe cpv3. I had a blade cp between there and hated every second of it. The axe cpv3 is heavier so it is a little more sturdy. I couldn't get the blade to hover to save my life. I got the axe to hover spot on on the first flight. Only down side is the tail motor. If you don't let it cool down between runs you will burn through them like candy and they are not cheap ($30). Although the new blade cp uses the same n60 tail motor and sells for $6 online!!!!!

If I can give you any suggestions it would be to look at what the local hobby store stocks parts for so you don't have to wait forever for parts to come in the mail. Nearly every store will stock eflight parts.

Good luck and happy flying
