the reverse thrust should work if you set "brake" to 100% and then throttle up, with default engine settings - but can be changed to different inputs

you need to brake while the engine is still producing thrust, if it's displaying it in negative kN then it's working
you can also rebind the reverse thrust to a different input like an AG or slider

use an aerospike engine on the front of the ship or use a jet engine on the front

@Aquaflames4571 yeah, that's what I'm talking about. You need a trust reverser if you don't trust your plain

@FriendlyFin @YaMomzBox420 @OmniExplorationDivision sorry I ment trust reverser and I don't think you just need to use break because I saw that that you need to mess around hidden property of the engine

break slider

I don't trust my jets either... You just gotta continue improving your designs so that one day, you can trust your jets 🥸

I think its break
