Mrasmm,
By your attached post, does that mean your going to go with the Futaba Servos? Just curious.
Heat Problem: I think I'm stumped, you've done so much testing and taking readings of all the test and still run hot. Even with the controller out of the picture and an outside power source. In your pictures, Pic #2, post# 2920, the chip in the upper left hand corner, marked "324 EZ3H526". The third lug from the left, looks weird, maybe a cold soldier joint. Really hard to tell from a picture.
Grasping at Straws: Hmmm, you're really up there in altitude in Utah. That would fall into the equation to a limit, it would take more head speed to get off the ground than it would me, at 738 feet altitude.
Got this off the web researching: One of the three highest states in the union, the Mean Elevation of the state of Utah is 6,100 feet above sea level. Water boiling point at sea level 212, , Indianapolis 210.7, Utah 200.9. Just trivia.

hehe i guess it will depend all on if I can get her back in the air or not =P
here is another pic of that solder. It does look funny...
yeah, I was wondering the alt too, I would just ask wick, but he hasn't been around for a bit =P I don't know what the exact alt is right where I live, but it's somwehere between 4500ft and 5000ft. That could have something to do with it too....
hrm... the weirdest thing though, I've had 2 or 3 flights that didn't heat up the motor too much.... shesh.... what could cause that =P bah, back to the drawing board.... I wonder if somehow the main bearings could heat up or something, or maybe don't spin quite right at high revs when they spin real smooth at lower speeds or something..... bah, who knows =(
hrm, didn't upload my pic.. I'll try again.
I couldn't find a data sheet on that EZ3H526 part you were talking about anywhere =(
