I like the Mini Titans myself! Just thought I would throw that out there. By the way how good are you with the 400!

the 450 is a trex knockoff. suppose to be able to use all the align parts. bought just the frame. on the b400 ive had it since xmas, i can send it out and bring it back tail-in. i am hovering pretty well but dont have the trainer landing gear off yet. my mentor keeps urging me to fly without the gear but i have seen it save me and also crash me so im on the fence about that

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

You have a number of options to go with. Since you are still beginning you do not need a high end scorpion motor or one of equal performance. I agree the 3500-3700kv range is just right. If you are willing to wait quite some time, order a turnigy motor from hobbycity.com. Those are cheap and will work better than your eflite b400 motor. When I say willing to wait, I mean it could take over a month to get I know people who ordered batteries and paid a LOT for shipping and have yet to see them since they are shipping from Hong Kong or Singapore! You might be able to luck out and get one from a U.S. warehouse and get it sooner. Another option would be to buy a stock align motor. Or if you want to buy a motor you could potentially have for a long time and will give you a higher head speed go with a scorpion, xera, or neu motor! IMHO I would go with the align. not too expensive, more power than eflite, and you wont have to wait. Spend the money for a more expensive motor on a nice electric kit when you upgrade from the clone!!! Good luck!

take a look at xheli.com or hobbypartz.com, running the Exceed 400 Alpha series on both my EXI450 and Trex 450XL, great outrunner motor, and shipped to your door in 2-3 days, free shipping on orders over $25...i use both sites depending on my needs...hope this helps

converting over to the "Dark Side"...Trex 450 clone...HBK2 still #1
