Hey, I need some help building a quadcopter. I have parts I am going to buy, and would like to learn how to build the quadcopter. I am open to critiques and really need help. I am going to apply for a prestigious high school and need help soon.



here is the parts, i just need help building it....



also if you know other parts that are about the same price and are better, tell me please..........



How to build a quad-copter

I need …

  1. DJI 450 flamewheel
  2. D2830-11 1000kv brushless motor
  3. RCTimer 30A SimonK ESC
  4. KK2.0 Multirotor LCD Flight Control Board w/ Updated Firmware
  5. Turnigy 9x 9ch Transmitter w/ Module and 8ch receiver
  6. Quad flyer Propeller 10”x4.7”
  7. Turnigy nano-tech 3000mAh 3S LiPo
  8. IMAX B6-AC Charger/Discharger 1-6 cells
 
Those motors are rated for 10" props on a 2S lipo. Watch motor heat. Or consider 9" with the 3S, or 10" on a 2S (3S route is better long term). A lower kv motor would be better still.

You'll also need servo wires because the KK2 doesn't come with them, and a power distribution board or harness of some kind unless you planned on making one, but you have to wind up with a connection between the battery (probably has XT-60 connector) and that harness to connect to your ESCs. So if you're building it, make sure you have a female version of whatever your battery comes with. And unless you have a thermo-nuclear solder station, buy the battery with the desired connector -- don't attempt to change it.

I don't know how the RCTimer ESCs are terminated. The motors are 3.5mm bullets. You may find the ESCs & motors are collectively lacking wire length to power all four ESCs on the center hub without extending some or all.

MM and I have owned the Turnigy 9x. We're both flying the Taranis now. If you've got the $$, consider it. Unless you're really addiction-resistant, this won't be your only quad!
 
thnx a lot, really. So you reccomend me to get ...

1. 9" Props that are 3s
2. A lower kv motor
3. Servo wires
4. A power distribution board (which one would you recommend?)
5. A harness (which one would you recommend?)
6. Baterry and charger (which one would you recommend?)

Any recommendations on what to buy? Specifically, the models?
 
If you're gong to use a 3S lipo, go ahead and try 10" props, but if you can't touch the motors with your fingers after a flight, you're probably over-heating them.
Getting lower kv motors with an appropriate 'S' lipo will ease that over-heating risk and give you more lifting headroom for cameras and stuff later.
You can use a power distribution "harness" (just wires, they're all fine, just get the right battery connector), but my favorite board is the Quanum PDB with an integrated 12v and adjustable BECs. You have to solder to it, but having the two BECs onboard keeps your build cleaner. The HobbyKing PDB is good too. It has no BECs on board, but it has 3.5mm bullet connectors, so if the wires reach, you don't have to solder.
I use the Turnigy AccuCell 6, and it works fine. They're all probably pretty good though.
Look for an adhesive foam pad to mount the KK2 on, and consider buying the plastic case for it if the controller will be on top, in the open.
Check that your power system is all 3.5mm bullet, and XT-60 (battery connection) and you should be fine.
 
So get the Quanum PDB with integrated 12v and adjustable BECs, some adhesive foam pad to mount the kk2, a plastic case, 3.5 mm bulket power system, and XT-60 battery connection. Right?
 
That would be my recommended adds to your list, yes, but you need to decide if "Plug & Play" is your goal.
If so, you want to keep that in mind when choosing parts.
You might be better off with the HobbyKing power distribution board (currently out of stock in US). But now looking at your battery choice, I see no Turnigy nano-tech 3000mah lipo with an XT-60! They all have the 4mm bullet connectors.

(see that red connector at the end of the battery wire?)
I've standardized all my gear on XT-60, but if you want to use the nano-tech battery and HobbyKing PDB, you need to adapt the battery (or MacGyver it together somehow):

OR buy a battery with XT-60 on it already, or change the battery connector to XT-60 (requires a solder station). If you elect to change the battery plug to XT-60, don't cut the wire off. De-solder it from the old connector, hacking it apart if necessary. The bulk of the heat you need is to "tin" the wire and if it is already tinned, that's half the battle there.

The PDB choice is complicated by the fact that the HobbyKing PDB includes the power lead, pre-terminated with (female) XT-60:
Distro3(1).jpg

This means it will plug into your battery (if it has an XT-60) and your ESCs -- you need to do NO soldering at all, but you also get no integrated BECs.
The Quanum board would need an X-60 power lead (in) added, and you could either add 3.5mm bullets, or remove them from the ESC power leads and solder the leads on (what I did):
55556.jpg

The choice comes down to your ability/desire to solder, finding an XT-60 female power whip to add to the Quanum board, and whether or not you feel the 2 BECs will benefit you in the future.
I've used both boards. I like the Quanum for my 4S quad because I needed both 12 & 5volts. I removed the connectors from the HobbyKing board because my ESCs had 4mm connectors, but that one may work very well for you, and you can deal with the need for non-ESC 5v later, and that quad runs 3S, so 12v (or close enough) is already there.

And the props are 9" with probably a 4.7" pitch. The 3S refers to the lipo battery. S somehow refers to cells, and lipo cells supply 3.7v each, nominally, which comes to 11.1, but charged it'll come up over 12v.

So if you want plug & play, plan for it by buying parts that fit together. If you don't care, and can solder wires, your quad can be cleaner and a little lighter. If you want we can work up an actual buy list with part# or links. Decide on the plug & play thing first.
 
I think I would want to do a plug and play because this is my first build, and it would be easier to do it this way now. Maybe next time I will do it on a soldering iron basis. Thank you for making a list for the parts.
 
Ok, then your motors and ESCs are fine -- both 3.5mm bullet. Go with a HobbyKing power distribution board, also with 3.5mm bullets
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=28255
and get a battery with an XT-60 connector, so it plugs into your power distribution board without modification, or buy the:
http://www.hobbyking.com/hobbyking/...s_bag_USA_Warehouse_.html?strSearch=XT-60 4mm
Since the power distribution board has a "female" XT-60, that part will adapt the battery to the board.
Your KK2 controller will get power from one of your ESCs plugged into the output bus, and the receiver gets power from the controller on the input bus.
You may have to let the ESCs fall on the arms anyplace the wires allow, but just zip-tie them down and they'll be fine.
 
I think you decided to lean towards no soldering, so we covered what is needed from motors thru ESCs, PDB, power adapter and battery. XT-60 isn't common on enough batteries, so go ahead and get the battery you preferred with the 4mm bullet connector and then get the adapters (2 in a bag, although you only need 1).

I know you're buying from RCTimer, for the ESCs at least. This is your build so it's your purchase list. If RCTimer has parts that plug in cleanly get those. I only spec. parts from HobbyKing because they have so many of them. But they don't sell SunnySky, so I'm not all about HobbyKing. I buy from Banggood and RCTimer too.

You'll need some short "stand-offs" to mount the distribution board, but they are available locally from any good hardware store. The frame may or may not come with velcro for the battery but you can get that locally too. If you're happy with the selections, go ahead and order it up. Otherwise, ask more questions.
 
So, could you right a list of the actual parts, so I know what I need to buy? And maybe what I need to attach the parts?

Thanks for all the help,

Jack
 
Tell you what. You put a list together with links to each part. Start with the list at the top of this thread, add the HobbyKing PDB, and the 4mm-XT-60 adapter. You have everything here, just put it together in a list. All you need to attach the parts is your hands, and maybe a screwdriver or hex driver -- that depends on your frame. I don't know how the flamewheel goes together, but the arms connect to the center with screws and the top deck attaches to the base with four tall stand offs.

If you put your list together, I'll be happy to check it. But this is your quad and you're building it. So you gotta step up here. If it makes it easier, find a good picture of one built and put a mark on each part as you identify your source for it.

If you didn't mind soldering, I'd say just get a kit like this: http://www.amain.com/DJI-Flame-Whee...roduct-Feeds&gclid=CPrI_tzuwcACFaTm7Aodo1cA2Q
The flame wheel frame has an integrated power distribution board, but you have to solder onto it.
 
  1. DJI 450 flamewheel
  2. D2830-11 1000kv brushless motor
  3. RCTimer 30A SimonK ESC
  4. KK2.0 Multirotor LCD Flight Control Board w/ Updated Firmware
  5. Turnigy 9x 9ch Transmitter w/ Module and 8ch receiver
  6. Quad flyer Propeller 10”x4.7”
  7. Turnigy nano-tech 3000mAh 3S LiPo
  8. IMAX B6-AC Charger/Discharger 1-6 cells
  9. The Hobby King distribution board
  10. XT-60 4mm battery adapter
So like that?
 
Where are the servo leads? You need at least 4 to connect the Turnigy receiver to the KK2 controller.

If you insert a link to the actual part you intend to order, I can make sure, for example, that the battery adapter is adapting the right way. I think I checked it and linked the correct one above. And you need 2 CW props and 2 CCW props -- seeing links would allow me to check that.

Whoever actually orders this stuff (assuming you don't have a credit card or PayPal account yourself) is going to want to get right to the correct parts, so they'll need good links anyway. And you both want to be sure you're getting the best value, so it's up to you to shop thoroughly, and consider the net cost including shipping, tax etc. If you wind up with the wrong parts, because you didn't do your research, someone is going to be irritated, right? There will be a few extra things you'll have to buy locally, like screws or bolts to mount the motors, etc. but you need this "buy" to pretty much get you into the air.

Which parts are you buying from HobbyKing? Which can come from a more local warehouse than the international one? What does that save you in shipping if anything? What parts are coming from RCTimer? Are there any other vendors you're using with this initial build?

When you get into a quad this size, it's a pretty serious hobby. There's a lot of learning you have to commit to. The only shortcut that works is buying something off the shelf. If you want to build, be prepared to get a little hardcore. It's great you want to step up to it, and a lot of people are around to help, but you have to STEP UP -- no one can build you a ramp. When you're at the controls of something that can do serious bodily damage, there won't be any "ramps" then.

Just repeat the above list (plus the servo leads) and include a link to each part you're going to order. You do that by clicking in the address line to highlight it, copy that text, use the "link" tool here on the forum and pasting the link text in.
 
They are "servo leads", but they are difficult to search for because of inconsistent descriptions. Here's a bag of ten, so you'll have a few spares.

Your receiver ("9X8Cv2" comes with the Turnigy 9x radio) will have a bunch of pins on the side. There is one column of three pins for each channel. The wires you see in the picture are color-coded; brown = ground, red = +"voltage" (in this case, 5v), yellow = signal (the pulses that communicate instructions on that channel).
On the Turnigy receiver, and most receivers, the yellow lead goes into the top pin in each column. There is a slightly "cleaner" new wire set that only sends power and ground on one three-pin connector and just sends signal down all the rest.

But this is only available from the international warehouse, which means a pretty large minimum shipping cost. If you find you have to buy from the international warehouse to get what you need, add THIS set of "servo leads" to your order. It's called "HobbyKing Super Clean RC Male to Male Extension set". But if you can get by with an in-country order, just get the regular ones further up in this post and you'll be fine.
