Can use a Mavic Air 2S to make this job?

The Air 2S is flown using Virtual Stick controls which means it needs a super solid RC connection at all times in order to fly safely. If the signal drops out at all the aircraft will stall. Flying around tall trees is a good way to have a spotty RC connection. 

The camera is nice but the Virtual Stick controls make it less applicable for what it sounds like you will be doing.
