Like the last XF, this was mased (More loosely this time) off a lego plane I made. It turned out a bit smaller than I planned, but it works, so I'm happy. Pitches down a bit below 480mph, and it's not especially fast, but it's controllable (Especially with a joystick). I spent ages trying to make this without the vents on the side (The lego one had the inlet behind the cockpit, as well as a completely different engine style), but failed to make it work. If its possible to make an inletless jet (or one with them hidden), please enlighten me. Armed with twim miniguns. Oh, and if you could pretend the bumps on the bottom don't exist, that would be great.
