By the way, you are one fortunate guy.  That = antifreeze=20 that was used to put out your brake fire, well, it has a flash = point of=20 220-260 degrees F, depending on where you look.

No familiar with the SA-16, Bob, but are both props turning same=20 direction or opposite - would make a significant difference in whether = there=20 is a swirl (my spell checker says OK {:>)) effect or not.  If = in=20 opposite directions then I would agree, if both props rotating in same = direction then harder to say.
