If you want to be able to do things like go inverted, loops, flips, etc, and have the patience, skip the FP and go for a CP (Collective Pitch). A good CP is just as easy to learn on as a good FP. Yes, the FP will be easier to setup and fix, but the CP isn't THAT hard.....

A general rule of thumb for RC heli's for learning on is the bigger the better. The larger the heli, the more stable it is and thus easier to fly. With that said, money becomes an issue as you go bigger. I personally would recommend a heli in the 450 class. A good one that includes a decent radio is the Blade 400. If money is not an issue at all, the TREX 450 SE v2 is the cadillac....or actually Ferrari )

BUT with all that said, if you really want to improve your learning curve, and save money in the long run, get a simulator! It will be your best investment.

You will get a ton of opinions.....I've noticed there are two "sides" to starting out.....some say go fixed pitch, others say go CP. I am one in favor of CP since I had and still have no desire to fly a FP heli. None are wrong.....just simply opinions so do your research and make your own choice.

Good luck man and welcome!
