Hi all,
I've heard of their being an overheating problem with this receiver, if so what can be done to alleviate it? Or have Futaba sorted the issue?

What they were advising was to run the rcvr mounted on its side, not the bottom.

What does it do when it overheats? How long does it take to get there?

And color me confused, how will mounting on its side help? Is there some additional heat sinking the plastic case offers on it's side?

it usually overheats about 15-20 mins onto a nitro race

the parts that get hot are on the bottom on the case so if they are up in the air they stay cooler

some work fine and some overheat shutdown

you can test yours by putting it in a sealed shoebox with temp and heat it using a blowdryer to 160ish if it shuts down you have a bad one

I have some of both with both color stickers.....
