In order to use a FTDI adapter to load the firmware, you need to connect to the FTDI port which is on the picture in attachment. You can see the pinout label on the board bottom, should batch exactly your FTDI adapter.

Project SCAD

So the final outcome of my project was that although it is possible to control a quadcopter via android application it is not feasible with a Raspberry Pi sending the data via serial communication. Really wishing we had done more background work on this project. Myself and many others were looking forward to seeing it work. At least I now have an awesome hobby to look forward to once I can afford it!

You can't do that directly.
Each sensor orientation need to be changed in the def.h

so I see....this is the vtail that MrClean was setting up with you ...I just found your robotshop website...(nice site)...in a sketch you posted for him. It set the board as

#define FREEIMUv043 // same as FREEIMUv04 with final MPU6050 (with the right ACC scale)

Is that the right brd? it is the ready to fly quads black ezpro3 board..

I would have guessed this board...

//#define MultiWiiMega // MEGA + MPU6050+HMC5883L+MS5611

If it's the same board, here is the file i sent to that guy.
To change the board orientation, you need to perform tests with the MultiWiiConf and the graph that is in there to correct each sensor orientation in def.h.

MultiWii Sensors Orientation

Code:
#if defined(FREEIMUv043)  || defined(MICROWII)
  #define MPU6050
  #define HMC5883
  #define MS561101BA
  #define ACC_ORIENTATION(X, Y, Z)  {imu.accADC[ROLL]  = -X; imu.accADC[PITCH]  = -Y; imu.accADC[YAW]  =  Z;}
  #define GYRO_ORIENTATION(X, Y, Z) {imu.gyroADC[ROLL] =  Y; imu.gyroADC[PITCH] = -X; imu.gyroADC[YAW] = -Z;}
  #define MAG_ORIENTATION(X, Y, Z)  {imu.magADC[ROLL]  =  X; imu.magADC[PITCH]  =  Y; imu.magADC[YAW]  = -Z;}
  #define MPU6050_I2C_AUX_MASTER // MAG connected to the AUX I2C bus of MPU6050
  #undef INTERNAL_I2C_PULLUPS
#endif

I am very interested in buying one of these from the website. I just have one question though. Is the multiwii board that comes with the combo already setup and flashed for this platform? I'd like to know since I haven't had any experience with this type of flight controller or y-tail platform yet, and may need to do some research on how to configure pid's to get stable flight and 3d. Thanks in advance for your help

Thanks Ocso, your reply and information is much appreciated. I'll look into the add ons, and inquire with the company which will be my best setup options.

The videos of this multirotor that I have seen, as well as it's looks are amazing. I just need to figure out whether I'm going to go with the 400 or 500 size class. Ahh the rough decisions we have to make nowadays
