I have taken apart my F550 and removed the Wookong because the IMU never worked. That story is in another thread.
It seems like i could use Phantom Naza in the 550 frame. I have not opened the Phantom yet. Has anyone tried it?
OK! I will try to save the configuration and move the Naza to my 550. If everything goes to h**l, then I will share it here and warn others of doing the same mistake.
