Hi all, i finally got some time to mod my phantom and here is what i did. 1- added prop-guards 2- modified the vision camera to be face 90 degrees down with wire and extra dampers 3- added some foam to the feet to make a bit taller 4- change the antennas on the control and the wireless extender the problem im having at the moment is that while flying it just keeps moving and as well it keeps going to the right all the time. i tried recalibrating the compass but no luck. any other ideas? do i have to recalibrate the rotors? if so how?
