Better throw in my two cents here too... IF I was to do things over again... being a little wizer now.. emphasis on little eh Zim... lol... I'd have started with an EXI 450... for the following reasons...
First off ANY heli thats RTF... isn't.... They may fly sort of out of he box but you cannot get away from setting up the heli yourself... just doesn't happen... secondly a collective heli like a Trex, Guai, K2\K3, belt or whatever, can't be flown out of the box by a beginner... Thats another just aint gonna happen scenario...
I personally would NOT be buying the overpriced Trex and K3 heli's... period and especially as a beginner... Align's line of heli's are very expensive and still require setup and parts unless ur buying a very overpriced RTF... The K3 is a slightly smaller and 'fixed' up King 2 but again for much more money than its worth... Its cheaper to get a discounted K2 and bling it out and still be cheaper than a K3...
Zim and warpnine gave you the correct and probably the best way to go about this habit... err hobby... You will NOT be able to fly right away even with a FP heli, IMO... and a ccpm is even harder yet... This is a slow and difficult hobby to learn in... there's a steep learning curve in fly'n but the mechanics are much simpler than you can imagine... Once you get over the intimidation factor of looking at this complicated whirl'n mass of plastic, metal and carbon fibre you'll see just what a B E A U tiful piece of work heli's are... They're great... Te one thing I'm very greatful to the K2 is teaching me to be a heli mechanic because its as Zim say's... ur ALWAYS set'n it up...
If you want to learn how to fly on a relative easy and smooth heli to fly I'd have to say the EXI is by far the nicest... There is one known weakspot with it but its a $E20 fix and thats the tailbox... Other than that it will fly nicely when ur ready to go... You will need a radio, motor\esc and servos. for the EXI... but you can buy all these AND the heli AND be fly'n cheaper than you would be by buy'n an RTF Trex or similar heli... Like mentioned there are LOTS of vids on setting up the heli and TONS of great people here to help make learning a pleasure and help you along as best they can... I wouldn't plan on taking short cuts with this heli... IMO you'd be having a hard time doing it and\or it would be much more costly... You have plenty of time to learn both and by learning both at the same time each will tell you LOTS about whats happening WHEN you are fly'n... For example if ur birds tail is twitch'n or wag'n hello to you... you'd know theres a problem and its the gyro.. needs the gain adjusted... Or a funny click or noise when spooling up... then the tailbox shears off... lol YOU ARE going to crash Right Out Of The Box so becoming a heli mechanic is necessary Right Out Of The Box too...
lol
Sorry for the long winded explanation but I didn't see how I could Readers Digest the info you needed down to 25 words or less... Other than... BUY EXI...
Welcome to the habit and happy ly'n
