Contract I'm working on wants me to fire the decouplers between 0-4000 meters altitude, while flying 1210-1870 m/s. I've tried staying low and burning liquid fuel, can't get that fast that low. I've tried going really fast off the bat... Can't get that fast before I hit 4k meters. I've tried getting it on re-entry... Seems to hit a terminal velocity below 1210 m/s way before I get back under 4k meters. I'm stumped. Please help.
