Quadcopter from scratch, wiring and components


I managed to build a quadcopter with the parts described in the post, with this 10DOF sensor instead and without a logic level converter. It works fine and now has an ultrasonic sensor and Bluetooth communication with my android as well.

If you consider using a Bluetooth module running on 3.3V logic, remember to lower the voltage from 5V to 3.3V with some resistors.

Hi guys!
I'm totally new to RC and Quadcopter stuff but i would like to try and build my own Quadcopter. I know some basic electronics but I'm not familiar with all the RC and electronic terms.
Now i would like to ask you pros if my setup would work and if the wiring is good. This is the components:
1 Arduino Uno Rev 3. $30
1 Nine axis degree of freedom IMU sensor ITG3200/ITG3205 ADXL345 HMC5883L Module. $35
1 Logic Level Converter. $2 Do i need this?
4 AX 1806N 2100kv Brushless Micro Motor (19g) $37
4 Hobbyking SS Series 8-10A ESC $26
1 ZIPPY Flightmax 2200mAh 3S1P 25C $9
+ Props, what size would be good, I would like something small like 5x3 or maybe even smaller, is this possible?
Total $140

Would these components work well together and is the following wiring correct/optimal?
I'm specially interested if the Logic Level converter is nessesary. The description of the IMU says "fully compatible with 3v-5V systems".

The IMU can be found here:

And the Level Conveter here:


And lastly what should i do with the red/black small cables from the ESC, is this correct?

And I'm sorry for my bad painting and/or spelling.

Thanks for helping out a noob!

I connected XBEE directly to HK2 board... you can do that if you use M5,6,7,8 as input pins for the RX

and free the UART1 RX,TX pins that are originally used for RX.


This is one of the features of HefnyCopter2... it is still beta and should be available soon.


I have recently made a sample very similar to your circuit.... the good news is that u dont need a logic converted ... as u can already use 5V as input to IMU .... and even if u dont and connect 3 V u can still use 5V in SDA & SCL as they are already have their own level converted....Please follow MultiWii config file so that u know the proper assignment of pins ... for motors & RX....

if u can make multiwii see the IMU then it is done.

Let me know if u r still interested in this subject.
