Quadcopter build

[Stunito0o0]

Hi guys,
i am not very familiar with quadcopters so i will need your help with building one.Let me start with what i want the quadcoper to do:
1.To be controlable, preferably by phone or computer
2.To be able to transmit real time video signal(don't care much about the quality, but i gues at least 360p)
3.To have a onboard GPS which can be programed (preferebly in real time)
I know that this is a lot for a first build but i think i will be able to do it with your help.
The thing is that i want to be able to program it not just assemble it.

I have chosen some parts:
Turnigy D2830-11 1000kv Brushless Motor
HobbyKing(Mystery) Blue series 30A ESC
ZIPPY Flightmax 8000mAh 3S1P 30C
RCT Spider FPV Quadcopter Frame W/ Landing gear
RCTimer ArduFlyer V2.5.2 Kit Flight Controller
or
RCTimer ArduFlyer V2.5 Kit Flight Controller
(don't know the difference )
maybe 10x4.5 propelers


So my questions are:
What else would i need to make all this posslible.
Are the parts i chosen good(and compatible) and if not ,what parts would i need and why?
What is telemetry exactly?
Which are the best propelers,and don't need balansing?
...
Everything you know is going to be a big help for me.So tell me everything you think that may be helpful for me.
P.S.The primary goal is long range flying(1,2,5,10 kilometers)as much as possible.Sorry for my bad english.

Motors - those should be good.
ESCs - Get a SimonK flashed ESC like the HobbyKing Afro or RC Timer SimonK ESC. 30A will be a safe bet, but you might even be able to get away with a 20A to save weight.

This is the reason you want SimonK:

Brushless ESC's aren't made specifically for multirotors, so they send the signal to the motor inefficiently. SimonK firmware fixes this. Luckily, there are a lot of factory flashed SimonK ESC's on the market now so you don't have to flash them yourself. For example:

http://www.rctimer.com/product_779.html

Battery - 8000mAh sounds good in theory, but for what you're building, it's going to be extremely heavy. Your battery is normally the heaviest thing on your copter and your goal is to shed as much weight as possible. That 8000mAh battery you posted is 644g. You probably want to be around the 3000mAh range. I run a 3300mAh 3S (3 cell) battery on a 450 quad and it seems to be just about right. Prior to that, I ran a 2500, which was fine also. I replaced that because it didn't have a high enough discharge rating and I was drawing power too fast, so it swelled up and became dangerous (useless) to keep using.

Great info on Batteries:

Frame - That's a good looking frame and will work fine with the components you chose, but I always suggest beginners go with the R450 frame because it's lighter and cheaper and you can easily afford to buy two frames so when you crash, you don't have to wait two weeks for replacement parts from Hong Kong!

Like I said - it's just a personal preference for me. The frame you chose will be just fine and looks a lot cooler and also has some vibration dampening stuff for your GoPro, so it's a better frame. It just all depends on what your goals are. At the very least, I'd buy a couple replacement arms so you have them handy in case of a crash. RCTimer sells those for $5 each I think.

Control Board - The Ardu board is pretty well known and documented on the Internet, so you should be able to do what you want to do with that. I'm not sure of the difference in those two listings. RCTimer doesn't always list a lot of info. You may need to contact them. One thing I do notice is that one says it doesn't come with the GPS module ("It not with the GPS."). The other doesn't say that and is slightly more expensive, so that may be the difference. Make sure you get the one with GPS. You can also look at:

https://www.hobbyking.com/hobbyking...i_PRO_Flight_Controller_w_MTK_GPS_Module.html

I'm not sure which is better, but ArduFlyer/ArduCopter/APM is very well documented, so you probably have the right idea with that.

Propellers - The following is HobbyKing's data on prop tests from the NTM motor that is very close to the same specs of the motor you posted:

Prop Test Data:11x7E - 11.1V / 220W / 20A / 976g thrust
11x7E - 14.8V / 412W / 27.7A / 1.485kg thrust
12x6E - 11.1V / 215W / 20A / 1.08kg thrust
12x6E - 14.8V / 430W / 29A / 1.42kg thrust
13x4E - 11.1V / 223W / 20A / 1.06kg thrust
13x4E - 14.8V / 400W / 27A / 1.48kg thrust

It looks like you're probably going to want to go with 11x7 props and 4S batteries. 1000kv is kind of in between slow-fly and a more agile setup, so it can go either way as far as how you power it. If you don't go 4S for batteries, I'd almost say to go with a 1200kv motor and smaller props (8x4):

http://www.hobbyking.com/hobbyking/store/__17345__NTM_Prop_Drive_Series_28_26A_1200kv_286w.html

This setup would be cheaper overall. Really the difference is lower kv/ higher cell count batteries/ bigger props is more stable. The opposite is more agile. So I guess it depends on your goals.



What else would i need to make all this posslible.

Transmitter & Receiver
Low Voltage Alarm
Wiring
Connectors
Solder

FPV Equipment (FPV Camera, Transmitter, Receiver, antennas, goggles/ screen, etc.) if you want FPV


Are the parts i chosen good(and compatible) and if not ,what parts would i need and why?

See above

What is telemetry exactly?

Telemetry is flight data - so if you have either OSD (On Screen Display on your FPV) or telemetry on your transmitter screen (or additional screen attached to the transmitter), you can get data on battery charge levels, speed, gps coordinates, etc. right in your hands while your copter is in the air.


Which are the best propelers,and don't need balansing?

A lot of props will come "pre-balanced", but I never trust that. Invest in a prop balancer. It's 10-15 bucks and it will eliminate annoying vibration, save your motors, etc. Balancing is very easy with two blade props. You just put them in the balancer and try to balance them horizontally and vertically. If they fall to one side or the other, you just use sandpaper to sand off some of the material from that side. It doesn't take much.

Hi thank you for your answer.
In the last couple of days i have been reading in forums and watching tutorials, so now i have a better idea of what a quadcopter is.
I chose different parts because of the learned in the past few days. I would appreciate if you can take a look and answer some questions.
-Frame(not sure if i need the AV Dome, but i want to be a spyder not the regular "X" frame)
-Motors
-Props
-ESC(i think the 20A version will be enough as well because i won't be driving the quad at full trottle for more than 10 seconds ,but better be safe than sorry)
-Arduflyer 2.5.2
-GPS
-Radio
-Battery -not sure yet, but i want to be the 8000Mah if it's possible
Future adds:
-Camera
-OSD(as far as i understood this is used to "mix" the controller readings like roll,pitch,altitude and such with the video coming from the camera)
-Video transmitter
-Video receiver
So this are the parts i have chosen(forgive me if i forgot something my head i a mess from so much information)
The main problem of the configurations is that it is too heavy.
frame- 486 g
motors- 400 g
props- 60 g
ESC- 128 g
Arduflyer- doen't say but i guess about 80 g
GPS - 13 g
Camera -58 g
OSD- 6g
Video tx- 66 g
Radio receiver- probably 5-6 g
Battery -644 g
Other electronics and wirings - 150 g
Total: ~2097 g

thats a lot..
So.. According to RCtimer.com the motors i have chosen with the props i have chosen are making 1370 g thrust per motor which makes 5480 g thrust for 4 motors at 100% thrust.
Which means that 1% thrust is 54,8 g ( 5480 / 100)
Which means that the quad will be able to take of with 38% of thrust ( 2097 g / 54,8 g/1% ~ 38%) i can't remember where but i read that for quadcoters the normal take of thrust is 25-30% or maximum 32%.I am not very good at mathematics so correct me if i am wrong.

My question is is there a way reduse the weight ,but keep the same flight time.Or some other option which will keep the flight time duration.

P.S.Please excuse my terrible english.
Cheers!!
