Sounds like you're doing well to go with a copy as your first heli. You will crash it and it will be cheaper to replace parts. Since you've got the frame, head etc...things that I would replace on the next crash would be bearings in the head, main and tail. The copy bearings tend to be crap. My EXI 450 pro bearings are so bad that the tail rotor shaft wiggled right out of the box (poor tolerance). The blade grips have too much play (once again too much tolerance). Make sure your blades are balanced as the knockoff blades are natorious for poor balancing. My EXI took two layers of 2 inch wide tape on one blade to get it to balance. I just threw them in a box and grabbed another set of carbons.
OK motor. Depends on the number of cells you want to use. 3S batteries are cheapest and easiest but one day your skills will drain them with amp spikes and the longevity of cycles may suffer. Right now you'll be ok with them as you will probably taco them in a crash anyway before reaching the end of their life. That being said. Any motor in the 3500-3700kv range will be ok on 12T to 13T pinion.
Cyclic servos can be any number of 9G servos ranging from cheap HXT 9G servos that work fine, to DS 410 digital aligns or HS 65MG analogs. All three work well, the digitals will allow upgrade to FBL down the road should you choose.
Tail servo and gyro don't skimp on! You do not want to fight a tail while you are learning. At minimum you want a GY 401/9650, but preferably a GY 520, Spartan quark, mini G etc with a digital tail servo like Align DS 520, Futaba 9257, or a number of others. I don't know about the cheapo tail servos as there are probably some good ones like Power HD, but I go with what I know on the tail.
Anyway hope this helps.
High Voltage just works better
