Hey thanks for posting! I will try the fuel and glowplug change first. I don't know what happened with the radio but all I did was switch the reverse the servo on the tx, and it worked fine. The cooling head is still the same color as always. I checked with a temp gun and it was about 289 almost 300. It was hot enough to make the engine die. The truck stayed at WOT for like ten seconds and I shut it down as fast as I could. But I haven't taken the engine apart to inspect it, but I will do this if the engine still overheats with the fuel change.
