I recently bought a RTF kit, but I still need an esc and a Tx/Rx. I need a little advice relative to what size/type of esc I should pick up. Also, will I need a BEC? This is what I have(will have):

Helicopter: Dragonus SA
Motor: Scorpion HK- 2221 –B
Servos: Packaged with Kit
Gyro: Art Tech AT-EG 201
Battery: XCaliber 3s1p 2200 mAh liPo

Also, how about a Rx/Tx? I was considering a Dx6i (2.4 ghz) or sticking with somthing a little less expensive such as a Futaba 7c (72 mhz). I would pick one or the other up used.

One more: Can someone point me to a location where I can do some reading about the sizing of each of the componants as well as the setup?

Thanks for the patience and help.

Well it's for sure not RTF(ready to fly). Anyway....

I'd say you need a 35 or maybe a 45 amp esc there are lots of good ones out there. No, you will not need a BEC, the ESC regulates the voltage for the RX and servos.

If you think for one minute your gonna stay with this hobby get at least a 7 channel radio. DX7.............

The 6i will be enough but it's easily outgrown.

my 2cents

That's right! Who told you that it was RTF???
And like JRjoe said get a DX7, you will be able to use it for future helis or airplanes, and a good ESC will save you headaches! My .02, and with JRjoe now you have .04 cents!

I dont suffer from mental iIlness, I actually enjoy mine!

If it where me and I where going to stay with the hobby, I'd go with either the Futaba 10c or JR's 9303. While the Dx7 is a fine Tx as you progress in the hobby you may find 7 channels too limiting and end up having to do workarounds to get things to work right, to much trouble in my book.

Which ever way you go welcome to the hobby and you'll be able to get the help you need here on RR.

If the wings are traveling faster than the fuselage, it's probably a helicopter.

gkup-sounds like you bought an ARF(almost ready to fly) not a RTF(ready to fly) heli. If you're serious about the flying get a radio that has more than 7 channels. Oh if you don't have a simulator GET ONE. It will save you a ton of $$$$$ in the long haul.

Damn that ground is hard! When's the right time to get out of this money sucking hobby?

Wow really? Come back to reality man! Why would a new pilot shell out $600-$800 for a Radio when he just spent less than $250 on his first heli? Plus these radios are seriously complicated to program. Oh and then there is the fact that the 14ch Futaba RX won't even fit in his heli!

The truth is that any 6-7ch radio from Futaba or Spektrum will work fine. The 2.4GHz models are the nicest, have the smallest receivers and are the most robust for these helis. Besides if you stay at this then you will most definitely own a different radio, not to mention heli, before long. But until you figure things out for yourself, there is no need to spend big bucks on it right now. Look at it this way, if you buy a Futaba 6EX right now for $199 and then later upgrade to the 10C, you will only be loosing $100 for the radio itself. The receiver will transfer to the 10C. Sell the 6EX for $50 and you are only down $50. That is a small amount of money in this hobby.

I wouldnt bother with FM radio, 2.4ghz is here to stay, it sorts out a LOT of issues with RF noise which has caused many a glitch. I should know...my little Trex 450 crashed a few times with this. Changed to a 2.4ghz set and never a problem since.

Get good tools, the allen type screwdrivers are a God send to this hobby. A pitch guage is a good thing to have...blade balancer is good...though you could make one...very easily.

When it coes to setting the heli up, ask questions if you struggle...the ESC is not always easy to set...and can cause misery if not done well.

If its a kit heli, go for it!!! better to put it together so you can see how it works.

Dragonus? I have seen a pic of one before now...neat looking machine.

Quality takes........time!

Thats bogus! Granted, 7+ channels would be nice... but you don't need more than that to operate a heli nor does more channels measure how serious you are about this particular hobby.

Thanks for all the information thus far. I won't be truly sure I will stay with this thing until after I have the bird built and learn to fly it. I do have a SIM and have been practicing, but I don't want to lay out a ton of cash until I know.

Looks like I'll be trying to pick up a 2.4 GHZ with 6 or 7 channels.

Still not sure about the ESC sizing logic, and some reference locations. Thanks again guys.

gkulp,
You're in the right track for choosing a 2.4ghz system. Seriously look into the Spectrum DX7 or the Futaba 7C because everyone and there mother has one or the other in which it allows you to easily buddy box as an option. However, if I'm not mistaken... the new DX7SE removed this feature. But don't quote me on that. Perhaps someone will chime in regards.

Good Luck

I will vouch for the T7C Futaba, great radio. I started off with the FM version and liked how easy it was to use. The menu is easy to figure out.

I waited a while for the 2.4ghz version to come out, same great easy to use system

I would err towards the 7 channel option, why ever not? If you are going to buy a radio (lets face it...it will last a long time) then get the best you can afford....I reckon that the 7 channel is the better compromise between budget and functionality. That extra channel can easily run a switched option like a Governor system if you need one sometime.

My $.02 is stay in your means. If you have to buy a used DX6i to get flying then do it. Its better then missing a flying season because you cant afford a new DX7.
