the little guy loves to run this thing in the middle of the afternoon - plus the exterior of the can is also used to mount the gearhead motors. The frame, if we can call it that, is a large retangular can from a surplus store.

Since he and his buddies are running this thing for hours in 100 degree + temperatures, short term solutions won't work. Additionally, everything is encased in that oversized ammo can with two exterior vents. So he doesn't really get an "A" for applications in innovative thermal management.

Anyway, I had considered heat pipe and cold plate for the controller and receiver . . . but being only a ME I can't come up with something that will keep the encased electronics cool when the ambient temperature is over 100 F without using a small generator to provided the needed power. Then suddenly his little automated ammo can becomes a big engineering project.

I am honestly stumped.
