fc board selection help for micro quadcopter

[abhinavbhopal26]

i want to make a micro quadcopter at home. it is very lightweight and will use 4 7mm 3.7v coreless motors. i want to know which FC board can i use? i have seen videos and articles where they have done it without any external ESCs. so i want to know which board which help me attain this ? for example, v929 or v939 boards have this capability but they are not available in india. i want a board which can be easily brought and is cheap too

It is true brushed motors doesnt need any ESCs. They can be directly driven using FETS. More about how PWM ,motor here

So by this the motors are controlled not to worry about it too much. Its just the average voltage control with PWM by which we control speed.
Brushless ESC is a totally different story.
brushed flight controllers can be bought from here http://www.banggood.com/Micro-32bits-Brushed-Flight-Control-Board-Based-On-SP-RACING-F3-EVO-Brush-For-Micro-FPV-Frame-p-1070068.html
I would suggest 8mm coreless motors because they pack more punch with better propeller of 75mm. 8mm motors can take load of fpv camera if in case you need it.
