Default Futaba R404SBS maximum operating temperature

Hi, I would like to find out what is the maximum operating temperature for the Futaba R404SBS surface receiver? I am operating it in a 1/5th scale gas buggy. As the receiver and battery boxes are close to the muffler, I was concerned about the temperature. I measured the temperature inside the receiver box with a Futaba temperature sensor and telemetry feature in my 10PX. The temperature reached about 70deg C during a regular run when the ambient was about 28deg C. So far there are no signal glitches or receiver failure. Thanks for the help!

Futaba does not publish (and I have never seen) any max temperature figures. Sounds like it is working fine, so I'd suggest simply trying to keep it cool between runs. Don't let it sit in direct sun, etc.
