Question Help on building my new quadcopter.

Hello Everyone. I am new to the world of RCs. And I have decided to make a Quadcopter of the following specs:-

Motor-BLDC Motor 1800KV . This is the same as in this one- http://www.amazon.in/1000kv-Outrunne...=sr_1_3&sr=8-3

Propeller- http://www.amazon.in/Propeller-Multi...ords=propeller

ESC- 30A SimonK-http://www.amazon.in/Folksrc-Brushless-Controller-Quadcopter-Helicopter/dp/B01BTRLVBY/ref=sr_1_2?ie=UTF8&qid=1476527441&sr=8-2&keywords=esc

Battery-http://www.amazon.in/2200MAH-3S-LIPO-BATTERY-25C/dp/B01H1UHUYA/ref=sr_1_1?ie=UTF8&qid=1476527666&sr=8-1&keywords=LiPo+battery

Flight Controller Board-http://www.amazon.in/Robodo-Electronics-Multi-Rotor-Control-Quadcopter/dp/B00ND40QXQ?ie=UTF8&psc=1&redirect=true&ref_=oh_aui _detailpage_o03_s00

Transmitter And Receiver- FlySky CT6B 6 Channel- http://www.amazon.in/FlySky-FS-CT6B-...ilpage_o04_s00

Frame- Self Made

Is it okay ? Will it work or not?

Thanks!

Sorry if my English is bad

That may work, may not. A lot of it depends on what your plan is for the frame. I'll suggest not doing a homemade frame since the frame design has a lot to do with the vibration dampening and overall performance characteristics of your quad. I assume you plan to make it out of wood, right? Wood was common with quads before commercial options were available, but G10 sheet and carbon fiber tubing is so much better.
- 1800kv motors are too fast. A typical quad using 10 inch props usually works well with 950kv motors if you are going to fly it with 3 cell batteries.
- Depending on the weight, a 2200 mah battery will probably be too small. My quad uses 10 inch props, and I run a 2200 and 1300 in parallel for 3500mah total. That gives me a little over 10 minutes flight time with a lightweight camera. If I put a Go Pro on it, I'd need to move up to bigger batteries.
- That KK2.1 flight controller will work. It's not the best thing on the market by any means, but it is simple to set up and will get you in the air.
- Get a better radio. Unless you plan to take a laptop with you every time you fly, you are going to need the programming features on your transmitter. Having to connect it to a computer every time you want to change something gets old very quickly. You also will probably wind up adding a second RC toy at some point, so having a radio that can save the programming for more than one is very helpful. I'm no fan of Flysky stuff, but I know the multirotor crowd is keeping that company in business. The multirotor crowd likes anything that is cheap I guess. You can get a better radio from Futaba, Spektrum, JR, or Hitec. But Flysky does make fully programmable radios that will work, at least until they break.

Your best bet will be to buy a factory build "X" type frame and then research what similar sized quads carrying similar payloads are equipped with. This is a pretty mature technology, so there is no need to experiment. You didn't say what camera you plan to carry or if you want GPS or autonomous capabilities. If you do, then you'd need to get a flight controller that has those features.

Okay, I understood that but now if I'm going to use the 1800kv motor, should I decrease the propeller size?
The problem is that the seller is denying the return and on the top of that, funds are running low and I am not able to buy a new set of motors.
So what shall I do now? Should I buy a more powerful ESC? Or will decreasing the size of propeller will work?
This is my first project and I am planning not to use a camera or gps etc.

You can't just go to a smaller prop and make it work. Props need length to produce static thrust. Yes, you can throttle down and reduce RPM that way, but you can't arm the quad without going to full throttle so that's not really a practical fix. You might do some searching around to see if anyone has run a 2 cell battery with a quad that size before. That would drop the full throttle RPM down to usable levels, but still not optimal. Even if that can work though, you'll need different batteries, probably a 2 cell 4000 or so.

What are you actually trying to do? You say you don't want to put a camera on it, so what's the point? Quads are ridiculously boring without a camera on them. If you've already spent your money and bought all of that stuff then it sounds like you are about to learn a lesson in researching things before moving forward with a project.

Oh ****. I used the same specs above. Unfortunately my ESCs blow up everytime. I think the combination of a 30amp esc (Simonk) with 1800kv motor is not right. So what to do now? I have spent all my savings on this but got this result. Whether spend again on 40a ESCs or on small sized props?
Waiting for any helps. I'm not good in English

That's what happens when you buy things and ask if you did it right later. If you had asked first you would have gotten the right things the first time. You will need different motors. That is the least expensive option to correct your mistake. You should be able to sell your current motors on Ebay. As I said above too, your battery choice isn't right either, at least not if you won't be happy with 4 minute flight times.

Did you just make a new account to try and look like a different person in this same conversation?

@jester No I didn't create a new account. Looks like sujanpatro has done the same mistake like me.
Anyway I just have to change the motors, only that much... For now I just want it to fly even if it is for 2-4 mins because my deadline is too near and I dont have the time to wait for a new battery to come here. I will change the battery to a more powerful one after December month. And will add a camera then only. Yes you're right it is awfully boring without a camera and even gps too. So I will definitely add it. Thank you jester.

Hey all i forgot to inform something important . After its crash landing i found that the battery was swelled a bit. But after 15minutes , keeping it away it was normal again . Is that battery fine to use right now after charging???
I'm really fearful of explosions.

@sujanpatro With due respect sir, please post your problems in your own post. Why are you asking it in my post ? (Not trying to be superior)

Also it looks like you have tested your quadcopter. Was it able to fly? Why did it crash?

MCBrendan- You will probably burn up your ESC with the motors you have. That will cost you more money, not just for a new ESC but also the crash damage. Wait until you can do this right. Unless this is part of a job you have, you don't have a deadline. Don't be impatient. I'll bet a young guy can find some jobs to do to make some money. Rake leaves, trim bushes, shovel snow, things like that. Get the funds together and do this the right way.
