Do you have a lipo regulator in your box? They make alot of heat.
Have you tried lining the bottom of your radio box with Rx foam that airplanes use. I put a 1/4" layer of latex foam on the bottom of my box. Alot of that heat is coming off the chassis.
I thought Futaba fixed this problem.?
Can you post this in the Radio&electronics section to rub it in for the "Futaba fan-boys".........please.
