So I've got a basic SSTO Spaceplane that mostly works. I could get into space in .90 with NEAR fairly easily. However, I had a problem then (that I ignored) but figure I should ask about now: I can get to ~20km with no issues. However, once I'm up there, I only have a few options: 1) already be on a ballistic arc, and fire my rockets. 2) have my engines flame out, slide down to ~15k, re-light them 3) have my engines not flame out by coasting up slower, but have zero control authority, slide down to 17k, repeat. It *seems* like I should be able to get higher, but I either am going to slow and my engines burn out, or I completely lose control authority. Any recommendations? (If it matters, I'm running a canard setup)..
