Question for anyone using the H3-2D with the Phantom main board upgrade: Are you able to (or do you even need to) upgrade the GCU firmware after installation? Since the GCU is now embedded on the new board, I'm not sure if it uses the "same" firmware as the original GCU. I know that the current GCU firmware is supposed to be 1.4 according to the DJI support site. But when I check in NAZA Assistant, it shows GCU firmware as 18.104.22.168. Is this what other people are seeing? I know the Zenmuse Assistant isn't supposed to work with the new board and the NAZA Assistant handles all the upgrading (so I'm led to believe). This is a "V2" version of the gimbal just shipped this week from Atlanta Hobby. Everything seems to be working fine, but after all the horror stories about "be sure you update all the firmware" I'm a little leery. Any insight appreciated -- thanks!
