Me too. My ESC is under the wing. I put my baro/temp sensor in there too and the compartment's never gotten above 76F. There is actually an air inlet to the compart, but most folks fill it with a pan servo, camera, or GPS module. I left it open and even stuck a cut-off plastic spoon 'air scoop' over it to feed air through the compartment.
