You have pretty impressive ROF's.. I have a long list of guns in the available arsenal.. from Magpul PTS Masadas, m60, m249, TM g3, CA G36, etc, etc, etc and according to my chrono some of them barely float around 30 BPS with my 11.1v 20c 5000mah lipo (100A continuous 200A peak discharge battery). They aren't built using high-speed gears, but some of them have magnum motors and even still don't have the kind of ROF that some people claim to have.
It's either BS guesswork or I'm jealous.
