GoPro heat issues

Looks like I'm going to have more heat issues with the GoPro hero 4 black at 2.7k 50fps. It showed up at times during testing outside the payload and it's happening all the time once mounted inside. Some of it I expected and hence additional testing. Only getting about 30 mins recording before it shuts down.. And that's with the lid off.

Might have to look at dropping down the resolution to see if that improves the run time due to heat. Not exactly worth having the hero 4 if it can't run even in a 19 degree room. 

Looking out on the web it would seem that a lot of people mount it in an metal cage, not really an option at 138g.

On a more positive front i might have managed to save 65g by removing additional batteries to power the pits. Depends a bit on how the testing goes on GoPro.
