I am looking at ordering a TREX 450 v.2 helo form allerc.com this weekend. I have a Futaba 9C radio and would like to stay Futaba is able but understand that some components are better made by different companies. Let me know what you think about this setup and if there is a better selection on something let me know. I don't like buying things simply because they are cheaper, I prefer quality and am a firm believer that you get what you pay for. I also want to be able to use the equipment in other micro helis is I so choose.
Here are the components I am 99% sure about so far:
TREX 450 v.2 with Hybrid aluminum swash
Futaba GY401 gyro no servo (Do I need a servo for this?)
Now the components listed on the site but again I would prefer to get Futaba or another make if there is something better out there:
GWS Picco +F/BB Micro servos (Not exactly sure how many I need and is there a Futaba servo as small and of better quality)
GWS RD8 SS Dual conversion Rx (Was hoping there was a Futaba equivalent)
Thunder Power 11.1 volt, 2100 MAH Gen 2 LiPoly Batt pack (Or should I stick with a 1320 MAH for weight?)
Hyperion Titan 50A HI-PRO Brushless ESC w/BEC (Again hoping there Futaba ESC that would be a better choice)
Needed equipment:
Please recommend a Brushless motor and anything else I forgot to mention.
I am new to helos and electric as well. I fly gas planes (and big planes LOL)
I know I just asked a ton of questions and I appreciate all your help. Thanks everyone.

HoovDriver, i recommend you get the HS-56 servos and a HS-50 servo for the tail. We have had great luck with the futaba 3108 servos but sell alot more of the Hitecs. If you want to grow into it i would get a Mega motor and a Ph 35 ESC. There is a equivalent Futaba rx called the i146. We would have to order that one. The 2100mah pack is a great choice. I know you are interested in another vendor but give us a try.

Good advice there - many of us fly with Mega 16/15/3 13T on 3S TP2100, CC35 (not CC25 - won't handle 4 servos), 3xHS56, 1xHS50 (tail), Futaba GY401 (great Gyro if you've got at least a 6ch TX). Good combo. There are other motor, battery and ESC options, but this combo is the most prevalent. Also, don't buy a cheap RX - this is an expensive heli - Berg 6, Sombra Shadow 3, FMA or maybe that Futaba model that Hover259 mentionned.

I have my T-rex in the air for all inexpensive radio gear except the transmitter JR X-347.
Since you are a beginner, I would recommend you saving money to buy a decent simulator and then flying helicopter later. However, you can try like I am doing for my T-rex:
- GWS receiver
- Three Nano +F HP (24 oz/in): aileron, elevator, pitch
- One Pico BB (10 oz/in): tail pitch
- Align 400L with 13T
- Phoenix-25 ESC
- Li-po 2100mA
- Gyro G155
Reason:
GWS servos take less current, fast response, and they are 10gram Nano and 6gram Pico). RX has great SINAD, and narrow bandwidth for good reception (only $24.00 for 6 CH). More than that, GWS RX V.2 antenna has only 25 inches long, and 500 feet radius working. Phoenix-25 has governor mode allows you to run at constant RPM independent with pitch settings, and all of Phoenix-25 are programmable (BEC, current detector, motor timing, cut off voltage). Best of all, Phoenix-25 has 13KHz digital switching rate, so it has less interference to RX. I have a Futaba G155 gyro available, so I used it. You should have a piezo gyro for more sensitivity. Transmitter should have exponential rate mode. This would help a lot while practicing flying.
