There have not been a lot of crashes due to the 6014 thermal issue. Lots of noise, but very few crashes. The failure mode is typically such that you can’t get the RX to work on the ground, so no way to really crash anything. To clarify, it is only the 6014 that has the pronounced thermal issue, which isn’t a beginner’s receiver. But it is still a good idea to try to keep all your electronics cool.
