Again, It was just above freezing... tell me how it will overheat at 35 degees
you are right... Overheating is a big think to look out for, and I sure will be removing that gimbal dome if the temps are over 50 degrees or so. also... wouldn't the app let you know you were overheating the drone?? IDK, an error I hope to never deal with.
If you block what is designed to receive a LOT of airflow in flight - with a plastic cover - you can certainly overheat a device even at 35 degrees ambient.
Now, I'm not saying you DID overheat, or that the gimbal cover should not be attached, but generally speaking I would not assume that 35 degrees means it did NOT overheat, - with the gimbal cover in place.
