good QA...also looks like a good reason to follow the suggestions HTC put in the notes about learning this bird...offline...overheating on WEP should be no surprise as the fighters do this as well...
To my knowledge no other aircraft suffers engine failure or fires if the WEP is left running until it maxes out, so I doubt this is modeled on the B29. When the WEP maxes out it just simply cuts off and begins to recharge. I burned my WEP out twice in one flight while climbing in the B29 and my engines never burst into flames.
