This post makes part of a complete guide to this flight controller. Unfortunately this products is no longer present in the hobbyking catalogue, but there is another good version which i would suggest in place of this one: MultiWii Lite V1.0 Flight Controller w/FTDI or, if you want to have automatic altitude holding features, MultiWii SE V2.0 Flight Controller w/FTDI which is the same version as the previous except for an added barometer.

Anyway, connecting motors is easy once you get your Multiwii board working under the GUI. To do this, you should have read my article about configuring drivers for FTDI UART USB adapter and have already configured and uploaded to your board the Multiwii code. This because in the picture in the right bottom corner of the gui will indicate each motor with a number representing the pin number printed on the board.

So this is easy: this case my pins are (starting from left-front, clockwise) 3,10,11,9.

Also A0 and A1 can be used for camera stablization gimbal servos (I will write about this soon as i’m still trying ways to achieve stabilization).

Connecting Rc Receiver.

RC Throttle -> D2

RC Yaw -> D6
RC Pitch -> D4
RC Roll -> D5
RC AUX -> D7
RC AUX2 -> D8

Then you need at least an AUX channel for arming and disarming, so you have to setup a switch on a channel of your tx-rx system and then connect this channel to the board to the pin D7, also if you want to switch flight mode (better using a 3 way switch) or to trigger the camera, or to enable features, you have to setup a second aux channel like i did.
Remember to enable the Multiwii AUX2 channel on the code and then re-upload it to your board.

That’s all, stay tuned for how to setup the camera sabilization with 2 servo.

Comments are welcome.
Ciao!
