One note* Where I said Eagle in the last post I actually meant the Falcon. Posting at 4am clearly wasn't a great idea. Oh I can fly them well enough I remember doing that in particular to the aeris 4a at one point, giving it six ram intakes and about twice the radials it had...slightly air-hoggy I know, but it ended up wanting to spin sideways at about 27km doing something like 1500m/s. That design actually runs out of air for the control surfaces before the engines choke. I need to upload that somewhere at some point. Anyway with the Falcon, the climb angle was non-existent. I treated it like every other space plane. I leveled it out after a 45 degree climb at about 18km, then tried to make it go as flat out as possible. I got it to like 7-800m/s before the speed started *dropping*. I thought pushing it into thinner atmo would help that out so I pushed it into a bit of a climb to about 24km. It went maybe 800m/s before the angle started dropping past the horizon and it started going down. Even lighting up the LV-Ns didn't want to save it. Gonna try it again right now I think though. See if I can make it behave a little better. Maybe I'm just doing the ascent slightly off. I remember the KR-X Sparrow BARELY making 80x80km orbit with ZERO fuel remaining and finishing the circularizing with the ion engines pretty regularly.
