The only recommendation that I can give is to get the best gyro and tail servo that you can afford. Please don't skimp on these!

Congrats on your purchase.. Good servos are the HS65MG's good speed and metal geared. a BEC is not needed, since ESC's of that size have them built in. A good ESC that I recomend is the Castle Creations, Pheonix 35. As far as motors go, I am using the Hacker A-20 6-XL. You can gear it up or down for what headspeed you want to run. It will handle from an 11th pinion to the 13th if you really want to wake up this little bird.
JR is ok, but you can get a logitech 2100t and servo for 104.00 at Amain hobbies. I am running this combo and can tell you that it is a good setup.

Question I thought the Align 450 Sport kits came with a ESC & motor. I'd stick with using them and spend the $$ on more batts insted of upgrades for a better motor & ESC that are perfectly fine for now.

Servos; Cyclic servos- HiTec HS-65MG. Fast, strong and not expensive. For the rudder a Futaba 9257 gets my vote.

Gyro; I have a Logictech 2100 on my 450SE v2 and like it very much. The instructions that came with it leave a lot to be desired, but once I understood what it was they were saying through the bad translation it's easy to set up.
The Rx will all depend on what Tx you use.

Good catch DumbThumbs. I totaly forgot that the kit came with motor and ESC.
+1 on keeping them and buying batteries.

The Logictech 2100T on my 450 and the Align GP750 on my 250 setup procedures are very much the same. Once set up they work equally well IMO.

Well I made up my mind not to buy a micro fixed pitched heli for my next step up from the MCX. I'm going directly to the TREX 450. I'm not going to waste my time and money on a fixed pitch heli. By the time it takes to build the 450 and set it up I'll be done all of my orientation training on the MCX.

you are going to luv that little bird.
Remember, take your time when you setup the servos, swash, and head. If you rush thru it you will have to start all over, and it will drive you crazy.
I luv thrwoing mine around. I crashed my 600 this weekend, and spent the day flying my 450 around. It's nice to have a backup.
Have fun and keep us posted..

Good luck with the build and keep us up to date on how it goes. A word to the wise... Don't trust that any assemblies were done correctly at the factory. It's a very good idea to take parts (like main blade grips, tail rotor grips) apart and make sure they are assembled right, are greased and screws have LockTite on them. I heard a story of a guy, first heli he built, wasn't sure about it being set up right so he inlisted the help of a more experienced pilot to maiden his new heli. The guy lifted into a low hover then BANG... Tail blade & grip flew off, hit the pilot in eye and ended up loosing it. True story or not, it could happen that fast, so take your time with the build an be 100% sure everything is built correctly. And if you get stuck along the way, we are allways here to help.
