TO BEc or NOT TO BEc...not just for Patrick

I got this info from a guy named Randy Moody at r/c dude hobbies, he did not use any testing equipment that I know of, I think it was best guess going by what he read on my servo's spec sheat and from info he's gathered over the years on the dimension bec's...he was supremely confident that my sport bec would handle at least four of the 5955's I mentioned as stated by dimension. No I didnt test anything.
