Sure this is not real world, but I’ve been in Rc since 1972 and we wouldn’t do anything like this back then! I’ve got my own personal history of “real world” and the Rc equipment back then wouldn’t survive anything like this! Just hope they don’t sell the crash drone on eBay!
A couple of YouTube videos noted that they routinely got 25 minutes or slightly better in flight time. And one was in cold environment where you might expect some impact to the battery and flight time.
