Hello! I've edited the file SmallFusionReactor.cfg to set ReactorTemp = 3000, but I still don't get significant thrust using the Thermal Turbojet. Additionally I'm unable to switch fuels, the turbojet will only select Atmospheric as a propellant. Other reactors, like the Pebble Bed Reactor, work fine and then the turbojet provides a lot of thrust and propellant switching.
I assume these issues are because the reactor temperature is still too high. Is there something more than can be done so I can make an amazing SSTO?
