OP here. I flew 2 batteries today. Temp here 85F, and a bit humid. Somewhat cloudy, but flew for the most part in shade. Temperature of the DJI RC stayed steady at around 124F-125F, checked after each battery. Underside of the DJI RC was about 118F-119F.
Yes, I had the screen brightness to full, and a screen recording running.
You are good. Commercial specs are usually 60C (140F) and that is a minimum; most designers go higher just to be safe. Most wiring and circuit boards can do 100C easily. The components are the limiting factor. I assume DJI is buying the best as China is leading the world now in electronics manufacturing (consumer and commercial, but not industrial yet).
Dale Carnegie referenced this in an anecdote long ago in his book:
"A company that sells electric motors encountered a customer complaint about their motors being too hot. The customer was considering terminating the business relationship, but the company believed to be the complaint to be ill-founded: they had done extensive testing and felt strongly that their motors met temperature standards. Instead of arguing with the customer, the sales rep started conversation with series of questions emphasizing shared beliefs and goals: “You should not buy motors if they are running any hotter than standards, isn’t that so?” The client agreed. The sales rep then asked about the temperature of the room in which the motor is located, and then continued: “If the room is 75 degrees and the motor is 72, would not the motor get hotter because of the room temperature?” The customer agreed — hard to argue with basic thermodynamics. By gently and positively asking about the situation in an honestly inquisitive, perspective-agnostic manner, the company was able to reassure the customer that their motors worked as expected. By avoiding argument and looking at the problem from the customer’s point of view, the company was able to keep the account."
