Thanks for the answer about thermal turbojets! I've looked at the reactor's numbers and this explained why antimatter reactors are so great, their temp gives them a great isp, and their wattage gives them an incredible thrust. Now, it's great to be making nuclear fusion planes and whatnot, but my mad creations tend to be on the heavier side (upwards 250 tons), and they just seem to destroy any landing gear I place under them, particularly during landings, which is not ideal. Any ideas for landing gear that could survive to extra heavy loads?
