forward swept fighter (space variant)

video tutorial: https://youtu.be/9dmf8QlHxnQ?si=N9Wk5LatcGQ_tHWP

to launch:
slider 2 to retract launch tower and lock heading
full throttle and stage
immediately follow an extremely angled launch to save fuel
turn on rcs when roll starts to become unresponsive
stop when apoaps reaches 100km

use maneuver nodes to finish orbital insertion, you will have to detach the plane after core runs out

note: as you detach the plane deploy solar arrays immediately to compensate for offset thrust

reentry: burn retrograde for as long as you can, then immediately flip prograde and pitch up around 33 degrees and retract panels

dont turn too much or you will flat spin

when speed is below mach 4 and below 20000m (the airframe itself max design limit) stage to detach rcs pod

you can now fly normally
