Default Blown ESC

I bought an Eflite Valiant as my 1st plane. Flew it two batteries and the ESC blew (30A). A club member gave me an ESC (40A) and I flew two batteries and that blew. Called Horizon and they are sending me a new ESC. They said maybe the heat in South Florida. Seems like an unusual coincidence that it happened twice. What could be a cause>

Thanks!

What was the measured current at full throttle?
Battery voltage, and rpm?
