Fractal, First of all, great mod, one of the best mods ive ever seen, Scott Manley picked you for a good reason, but as everything, its not perfect, I want to report a bug that has caused me a lot of nightmares. Sabre engines are quite bugged, when you enter rocket mode, the mod does not detect that and they keep overheating, even in space!!! to overide that, you of course need to put the precoolers and they just work fine but the air intakes need to stay open and as i said, even outside the atmosphere, rapier engines work ok in rocket mode but please, can you plz fix the sabres?, sometimes i dont put precoolers cause i use the rocket mode to climb up faster and the bug is really easy to fix, just include the sabre engine rocket mode as a rocket engine so the mod can overide the heating while the engine is at high speeds when in rocket mode. Thank you and keep the good work, youre amazing.
