My order for a VMax-7 went in the other day and today I thought I'd check if my existing VMax-6 would play ball

In the past, although it displays plenty of power, this engine has always stopped abruptly at some stage during most flights. Guess what - my 6 worked great this afternoon! I had 3 flights, in a blustery wind, and not one engine shut-down!

Is this an example of "Sods Law?"
