Here you go....

Sorry for low resolution, that's the limit of My old phone camera :giggle:

The old two rupee coin is for comparing size of board.
The free portion on the board needs to be cut off.

The total Flight controller is less than 50*50mm.

Off topic, but I would like to mention a trick I learnt a while ago. While dealing with macro shots with crappy phone cameras without AF, place a concave lens in front of the camera lens. Any kind would work: Magnifying glass,reading glasses, etc. :)

You would be better off using some other usb to serial interface. FTDI has gone nuts and they are bricking non-original chips on purpose.

Didn't knew that - But do you mean Concave lens or convex lens ?
convex lens (converging lens) is usually used as magnifying lens / reading lens not concave.

I am not using FTDI, it's PL2102 .
Seems the reset pulse from DTR is not doing the trick - always AVRdude sync errors :(

It's based on multiwii, f/w , check the multiwii wiki - I selected multwii, because it supports so many h/w.
In near future i will write my own code.
I can share the circuit I used, when i reach home.

nice thought friend i made the board with mpu6050 and hmc5883l. The gui shows well but the outputs to motors doesnt work properly in my case " " only two motors runs after throttle up.all motors only run only at tx high throttle that too only two motors at high throttle and other two at low throttle because i am facing lot of problems for stable hovering

look like the IMU/Compass orientation issue or motors connection/ directin inverted.

tq for early reply friends and i got the solution i just need ti tune my tx yaw stick to very fine resolution of 1494 reading then it worked fine even a slight change in reading will change the setting and then it starts to yaw. I think  i am succesful in making my very own custom design of multiwii. If any one need help for circuit can ask me
