Early morning flights will be a lot cooler, depending on where you are located. Otherwise, a two hour Thai massage is a great way to spend any cancelled drone time.
When you take off and land, just head straight upwards without going forward, so folks don't hear/see the drone from your building. That drone is fairly quiet after a certain distance in the air, so it won't attract a lot of attention. What borough/postal code are you flying from if you don't...
How long are you waiting? It sometimes takes a while to get full Sats. especially in a tower. Do you have more units above you? You can also place the drone on a taller box instead of the balcony floor to get quicker reception and avoid any metallic interference.
Operational swelling that is 'slight' is not that big of a risk factor. I think you are overly dramatizing the scenario. As I mentioned previously, if the swelling is more advanced, then yes, the batteries should not be used.
Which is a good thing to do. Remember, there are different types of swelling. The 5 batteries I alternatively use over several years have slight swelling from time to time and that is dependent on weather and how hard I work the drone. The swelling has not made it hard to remove from the drone...
