Help!

Wanted to make my own quad


Hello

Recently I was thinking about making either big drone for aerial photography or something really fast. Both with FPV module. So I started searching around and found few guides and decided to pick one http://bit.ly/2bGyYZa (long link from learnrobotix.com). But discovered that the list is missing few pieces (maybe more?)

1st) battery wires and possibly some other wires (there is something said about xt60 but the link is broken), especially for charger (have imax b6)
i found something

2nd) antenna/receiver, I see there are some modules as combo with transmitters but can I use "ordinary" one for quad and bind it with anything or do I hava to purchase the combo?

also the budget is only for the copter itself, the FPV (camera and receiver) will most likely have its own budget after i get this quad to sky. Can you please tell me what should I get or what should I change? I'll be really thankful ^

Hey!

So, building your first quad is an awesome learning experience. However, you want to do it right so you have a quad that would last along time and allow you to grow through it. I like the parts you've chosen, however, while they are cheap, you will have a lot of frustration with parts that don't work and poor documentation. It will give you a lot of headache. TRUST ME. You want your first build to introduce you to the basics, not all the problems. That's what happened on my first build.

Honestly, quality can be expensive, so what's your budget? I have some ideas..

Well, i would like to spend between 150 and 200 € (225$) on the quad itself, its not so much, but since I will probably make another quad in next year, I want to put more money into Transmission and FPV since they should be (atleast from what i read) compatibile with other stuff.

Also, something i forgot to mention, I already have one quad. Bought syma x5c which I found on every site as the best cheap drone for anyone that wants to learn flying (and it crashed dozen times but Iam getting better)

Go to getfpv for awesome parts. They are good quality and last a long time. Go to the mini - multirotor store, it has everything you need.

For fpv, I would suggest getting a fat shark predator v2 kit. It has everything you need for fpv. You can pick this up at hobbyking or getfpv for a good price. Sadly, fpv is not cheap, and you'll probably shell out 200$ for it. Neither is a good transmitter. But if you are committed, these are great investments that will last you a long time. I suggest getting an frsky taranis, or a Spektrum dx6, which are both great radios.

The sites is looking really good, I'll check it tomorow but already found them ship all over the world (bit pricey but nothing my wallet cant take).

Thing with FPV, I am still not set whether I want googles or just screen. Thing is, I normally wear googles and having another googles (or switching between them) is sooooo annoying, but as I said, not set on that, first I want to make flying machine, then decide how to go with FPV (counting two or three months)

Awesome! Sounds good. Btw, how old are you?

Iam 23.
Anyway, I took a look on that site and even tho it has many things, I got no idea what should I look for :-D I am that new into multicopters. But I found that on page with some frame kit, there is list of recommended motors and LiPos, so thats some start, but still I am lost.

Also I looked on both Taranis and Spektrum, and although they look really good and in hands of someone who knows what he is doing it can be really powerfull tool, I think its more overpriced for me, if you know what I mean. I know (or atleast I believe) that I wont use 80% of the stuff the transmitter has, since what I am looking for is really just having 2 sticks and be able to trim them and having as little lag between commands as possible.

Okay, that's definitely understandable - not knowing where anything is! So, any quadcopter has a few crucial, main components:

- Flight Controller
-Motor(4)
-ESCs(4)
-Frame
-Battery
-Propellers
-BEC(only if nessissary|Ill explain later)

The motors obviously propell the craft and make it fly. A basic differentiation of motors that is the first concept you should understand is "Kv", or rpms (rotations per minute) per volt.

Generally, the larger the Kv, the more torque is has. The smaller the kv, the less. This is a super basic explaination of it, and I would suggest looking up a more detiailed one later! But generally for mini quads, you need to have a small prop, so you don't need a lot of torque, but you want to spin it very fast. Generally, a common kv for a mini quad is 2300kv, which is a good balance of torque and rpms for a 5in prop.

On Getfpv, they have a huge selection of motors, and while they are more expensive, they are beautiful performers (I know it's weird calling a motor beautiful) and are great for a mini quad.
I would suggest the Emax rs2205 2300kv motors,

ESCs - I would suggest these: http://www.getfpv.com/lumenier-30a-blheli-esc-2-4s.html

FC - I would suggest the naze32 rev6, and upload a program called cleanflight onto it.

Frame - your frame is fine, but look around on getfpv because they have some really cool ones!

Battery - get a 1300mah 3s lumenier battery (sold on getfpv too)

Props - I would start with these: http://www.getfpv.com/propellers/gem...f-4-black.html

I should've been more specific about not knowing what specifications should every part have (like the really good explanation of Kv, how much C on battery, why esc with such A, etc.)

Anyway, I tried looking on getpfv, hobbyking and banggood to find your pieces (and possibly for lower price) and the result is.

Found:
4x motors (2x CW/CCW)

4x ESC but from Emax, since from my point of view (and also budget) I can't spend 80$ just on them (with motors, it would be 150$ and I am still missing like 6 other things), the ones i found cost 50$ with same A and same burst A (just can hold up to 3 cell but that shouldnt be problem)

FC - https://www.hobbyking.com/hobbyking/s...ntal_Pin_.html
I am really scared to solder pins on the FC (or pins in general, they are so small)

Frame - Iam happy with the one I found before, its pretty sturdy (atleast what people says) but the 30A ESC's may have problem to fit on arms (again, people write, but I think they will fit well)

Batteries - I am not sure how to decide the amount of C, so no luck there- I guess it will probably go hand in hand with the ESC's A but dont know how to calculate it

Props - why 3 blade over 2 blade? I found that 3 blade should be more efficient with Amps but also more costly. Is there anything else? Not that Iam not fan of it, I would totally want to try them cause I think they look cooler xD

Anyway, so far the quad budget is around 170$ and thats missing batteries, PCB, receiver and connetor (with cable) for the battery

Three blades is like an intermediate power setup, so thats why i chose them! they also look cool..
