Thanks for the very kind words!
Yeah I think I might change the climb rate to your suggestion, it should cover both bases nicely. The Tempest has always used turbofans with engines of similar vintage to the GE F404 used on the F/A-18 so I imagine the improvements coming about from the switch to a more powerful engine will be less extreme than that brought about from a switch from turbojet to turbofan. Since I don't really know anything specific about engine performances I might just leave those stats as they are, but I appreciate the feedback
