yes they are flaming out while in auto mode still on air breathing setting atm everything is symetrical in line, i took a picture its in the op. right now i have two nacelle and two radial air intakes. ive used the action groups before but for what ever reason even after toggling them the engines dont kick back on after flaming out. heres what happens when it flames out and heres the engines remaining none responsive after a manual toggle

thats not the problem though, like i said the auto isnt kicking in, so what are the criteria for it to kick in? its not by air intake so it must be altitude. in which case i need to redesign the engine block so that i can reach a height where the auto kicks in. otherwise it defeats the whole point of using rapier

mode switch for the rapier engines does not kick in for my design. So I modeled the profile of the F22 for my space plane, im in love with the stability of this design its super maneuverable and practically lands itself while remaining highly compact, my problem is the engines though. since the plane is so compact and runs off of two rapiers for what ever reason i dont get enough thrust for the engines to reach an altitude high enough where the automatic mode switch kicks in. the plane stalls out drops back down while still on a full tank of LF/oxi. i tried different air breathing configurations but none of them work, its really annoying. also if someone could tell me at what altitude the auto switch kicks in that would be great.

so i followed the guides (scott manly) i do the whole 45* turn at 10k i burn at apoapsis just like in the vid but my periapsis never equals my apoapsis its always an elliptical. is there more to it, am i doing it wrong? i would like to do a space station at 150k my rocket design is fine its very stable and has plenty of fuel i just feel like my trajectory is some how incorrect. or do orbits not work this way?
