Well I just did a little test. I flew for 4 minutes in a circle as fast it would go and then landed it.
The 4 in 1 ESC was cool to the touch. This ESC is rated at 20 Amps per motor and the most that I can get out of the IRIS is 18 amps total for all 4 motors.
Now if you have a shorted motor all bets are off.

It appears that the ESC failure was due to a motor failure. As replacing the esc one motor
could not get up to speed. I wanted to see how much heat the esc generates so I placed
the battery on top and on a cool day it isn't generating much heat.

I have over 300 flights with my IRIS not all in the same day mind you. They generate very little heat.
The battery on the other hand does get a little warm.
when you finish a flight and take out the battery stick your fingers in the hole and touch the bottom plate.
do you think that that is just battery heat?
Don't know, I fly when is freezing out and nothing except the battery gets warm.
I probably shoudn't say this to you but we get a lot of 80 degree weather

I believe it is a custom made 4in1 ESC that was designed by 3DR just for the IRIS.

I burnt up my esc and I am wondering if repetitive flights without a cool down period could have been the cause
of the failure
