You have to run them early in the morning. When the lows are in the 80's anything after 10:00 and your esc is going to over heat.
When I first got my Mojave and didn't know any better, I kept reaching thermal cutoff. I couldn't figure out why it would only run for 5 minutes before it stopped...
Probably 113F. It's not so much how hot it gets, so much as how long it stays hot without any breaks. When you get a month straight of 100F+ with no breaks. then it will cool down to the mid 90's for a week, then rinse and repeat.
Just hoping they keep power outages to a minimum this year...
Jarold posted this over on the Arrma Forum, thought I would share it here. Watch the vid, then when they replay it in slo mo watch how much stuff you didn't see the first time, crazy.
