I also use arrows for movement. Yesterday, I tried Recon for some squad Javelin action and tried the drone as well. It seems that it moves just alright, however “look up/down/left/right” is hard bound to arrow keys which means that I always look up when moving forward (making it impossible to navigate) and look down when moving backwards. Notably, laser pointer also seems to have the arrow keys bound to looking around. I have not found a separate section in controls for device operation.
PS This issue kind of correlates with unrebindable “6” for squad perk action.
