MX400 Pro comes with a HeliMax brushless motor and esc, which I've heard runs hot and is a little down on power. It seems most of the posts I've read people end up junking the included motor/esc and using a different motor and esc, which increases the costs.
Even though most Futaba tx's are very good, personally I don't like the 6EXH tx, and I think the 3107 servos are a little wimpy. Also, that 1250 lipo is too small. I don't know why they recommend such small batteries for an MX. The box my MX400 came in recommends a TP-1320. The MX is the same size as a TRex but you never see a battery that small recommended for a TRex. Yes, it will fly it, but flight times will be very short, the battery will get very hot, and the battery won't last very long. Good for a BladeCP, but too small for an MX400. I've got the 240 gyro, and it's fine if you're not into aggressive 3D, which, as a beginner, you would not be.
Not trying to discourage you, but, realistically, it will cost at least about $800 to get into mini heli's (MX400, TRex, Shogun, etc.) if starting from scratch. That will be with mid-range equipment that you won't need to upgrade right away. You have to be sure to include battery and charger expenses, which run at least $50 per battery, and about $100 for a decent charger. If you plan to fly more than once or twice a day, you'll need multiple battery packs. I have six 2100 Apex lipo's and an ElectriFly 4-in-1 charger, so I can charge while flying pretty much all day long. But there's an additional almost $500 right there, by the time you include buying a lipo balancer, which you'll need if you plan to maximize battery life. And it doesn't include the costs of your first crash, which, if you've never really flown heli's before, will probably happen right away, and often.
None of this includes any of the inevitable aluminum upgrades either. I used to work at a hobby shop when a guy came in wanting all the metal upgrades for his plastic TRex. Totaled out to be a little over $300. Combined with what he paid for the basic TRex, he could have gotten a fully blinged SE for less. And he still didn't have the carbon frames and pretty metal fasteners either.
The RTF micro's (BladeCP, Honeybee CP2, etc.) have a much lower entry cost if you're on a budget. Even these will need some additional costs for batteries, etc. My $200 BCP needed about another $100 to upgrade to lipo's, cheap lipo charger and symmetrical blades. Since I was getting an MX and needed a computer tx anyway, add another $200 for a computer tx. So my cheap little $200 BCP still ended up costing $500. And that's with just one lipo, before any crashes.
True, they have a much steeper learning curve and don't fly as stable as the larger heli's. But, if you get proficient on a micro cp heli, you'll find that anything larger is a piece of cake to fly. That's the route I took (BladeCP to learn on before getting my MX400). If it wasn't for my experience on the BCP, there's no way I could have flown my MX400 for 8 months before its first crash.
And don't let people convince you that you have to buy a larger heli because a micro cp heli can't fly in wind. It's not that the heli can't handle wind; their flying skills can't. I fly my BCP in the same winds the TRex guys fly in all the time without any problem. I've had numerous people come up to me and tell me they've never seen a BCP fly that well in that much wind before. I just tell them it's a matter of flying in Idle-up, with symmetrical blades, with lipo's, with a decent computer tx.
Like I said, I'm really not trying to discourage you . But if you have a budget (and who doesn't??), you do need to know what you're getting yourself into.
