Suppose that I fly my M2P on a day that is at the upper temperature limits of its operations specification, say 100 F. It is also a day associated with a high humidity level of 90% or so like we often see on the East Coast.
Then, suppose it is two days later. The temperature is still 100 F, but the humidity level is at a more comfortable 30%. This is also consistent with the East Coast, as we have a saying, "If you don't like the weather, wait a minute"...
My question is, would the higher humidity day provide better cooling for the copter's electronics due to the higher quantity of water particles in the air passing over and through it.
Intuitively, I would say that this would be the case. And the science is not new. After all, some race cars and even some aircraft use water injection systems into their intakes to more efficiently remove heat from the engine core via the exhaust, and combustion aside, the principal is still the same.
Also, I am purposely leaving the battery out of this equation, although I do realize that it is a significant factor as well in high - and low - temperature limit flying. It can be pre-cooled - or heated - in these cases - and I tend to do so as I near each extreme.
