Help for First Time Builder

[Kiatu24]

Hi there, I've been looking into building my own quadcopter. I have a lot of experience programming and a decent amount with electronics, but this is my first venture into buying quadcopter motors, ESCs, and batteries. So I was just hoping for a bit of help. I've done a bit of research and I found this nice page:

https://www.hobbywarehouse.com.au/articles/how-to-match-esc-motor-lipo-battery-rc-car.html

So my real question lies around the math and making sure I get parts that will work together. These are the parts I'm looking at right now.

Motors (x4):
http://www.hobbyking.com/hobbyking/...rushless_Motor_for_Multirotor_2300KV_24g.html

ESC (x4):
http://www.hobbyking.com/hobbyking/...Amp_Multi_rotor_Brushless_ESC_2_4S_OPTO_.html

Battery:
http://www.hobbyking.com/hobbyking/..._80C_Multi_Rotor_Lipo_Pack_For_FPV_Minis.html

So based on that article, the motors will draw 8A a piece, the battery can handle up to 56A, and each ESC can handle up to 20A. And the 4 motors will be wired in parallel. So by my understanding, each motor drawing 8A will total up to 32A, which should be more than doable for the power supply, right? (The only reason I picked these is that they are the cheapest options on that website and I'm on a pretty tight budget to try this.)

If anyone can tell me if I'm way off base or can recommend any other reading or any other parts, I would be extremely grateful. Thank you for your time.

Hi mate and welcome to the forum , what frame are you going to use ,This is were we normally start then motors and props to fit the frame
the motors your looking at are good to a 250 size racing quad
Also why are the motors going in parallel? each motor will have an esc so its own power
the ESC has no power out for the receiver or FCB so your need a BEC
What FBC are you looking at ?

Hi holtneil, thanks for the reply! And I apologize, I should've mentioned I'm a complete beginner so a lot of the lingo is still foreign to me. Well your first question, I'm building my own frame for it with my 3D printer. This project is more of an educational experiment so I don't need anything to be optimal, I just want it to fly for a bit. And I'll be making my own control board using Arduino, IMU, and some RF modules.

The second question, I just meant that each motor would be attached to its own ESC, and that would go back to a single power source. So I would wire them parallel instead of in series. I think maybe I'm missing something here though. Will I have to have a battery pack for each motor? Or can I get away with using one battery pack to power the 4 ESCs and Motors?

And I'm not quite sure what a BEC is. Again, thank you very much for your help. I appreciate it.

Hi mate what we do is make a loom from the battery to the ESCs or a power board, BEC means Battery Eliminator Circuit, this is beause the opto does not have a battery out for the FCB ( flight control board)
AS for the frame keep all the arms the same length as its harder to program up if the arms different

Take a look at this link. It is a glossary for basically all of the terms that you will encounter here on the forums. Here is a good calculator for helping you decide on parts.
