So i'm ready to move on to something i can build/modify. I currently have a P3A and trying to get the logistics of how to proceed. Is it possible to use the Phantom Transmitter with the F550? Also is the gimbal from the Phantom 3 compatible with the F550 as well? Also with the Naza flight controller can you use DJI Go? If can save on the cost of the new copter by using parts of the P3A i would rather do that. Since my P3A was bought crashed and I rebuilt it I would feel terrible selling it to someone and something happen later down the road due to a damaged circuit/servo/etc I did not replace finally giving out. I bought a Turingy HAL hex from the 1$ hobby king sale but starting to think the F550 is the way for me to go. Thanks for the help. Edit: Possible to flash F/W in P3A to support 6 motors?
