Thanks.

Don't know, didn't try it. Even if I did, I'm kinda limited by the power rating of my test resistors (between 1w and 25w). At 9v and 5-7A, output power is quite high. I'd have to invest in a set of higher power resistors if I plan to do this type of thing more often.

Even then, I think BEC temps would get out of control. I only loaded it to 4.69A max and it got quite toasty after just 1 minute - and that's with only 3.5w being dissipated on the BEC (88%). Assuming efficiency stays the same with 9v @ 5A output, that would be 5w of power on the BEC. Ouch.
