 Currently there is only a basic setup but as the development advances so will the documentation.
-Start by mounting the big quad deck on the frame. After that connect the ESCs according to the diagrams below.

   * Different PID tuning parameters might be needed for it to fly well. Currently this has to be [[https://github.com/bitcraze/crazyflie-firmware/blob/269730f369b4df34535708d13274abebacb71b5a/src/modules/interface/pid.h|hard coded]]. Later this will be saved in the EEPROM or in the 1-wire memory.
   * External battery voltage/current reading is implemented but no logic behind it, so don't run out of battery. You can connect the cable (MON port) and watch the log variable.
-  * The PWM output is set to 400Hz. Use ESCs which can handle this or compile with [[https://github.com/bitcraze/crazyflie-firmware/blob/master/drivers/interface/motors.h#L89|new value]].

   * **Be safe**, it is experimental software. Run all testing **without** props!
