Futaba R608FS 8 channel receiver failed, locked out, (red LED, all servos holding last position) at 124* F

Dual 6v, 5 cell 1500 mah packs... voltage @ 6.12 volts (voltage not an issue)

Heres the video that I did before I took the plane back into the garage...
Took the plane back into the garage, and about 4 minutes later, we have a working receiver again (you can see the temp)
Here's some pictures I shot of the "bad" reciever...... I've read & heard that the upgraded recievers of this model
have had yellow or white dots on the outside of the case where the antennas come out.... but I'm not sure as

Well, I proved my reciever fails under the sun in natural environental heat yesterday....I figured what the hell....I've had this longer than a
year... don't have a reciept... etc.... It's a loss/write off........
Lets do one more test for our entertainment!
Same results at about the same temperatures!
