This is my first design, the Swift. I know it's a bit simple, and doesn't have any function, but my 4x2 jet engine design gives this plane exceptional preformance.If you leave the fuselage empty, it can reach 1600 mph before running out of fuel, but if you want more flying time, you can load the first three fuselage block or all of them, which will give a longer flying time, but the max speed will be slightly effected.And this plane is extremely agile, you can use it as a fighter or a bomber.
BTW I didn't say the max speed is 1600mph, it's the max speed before running out of fuel, so the estimated max speed is 2000mph.
Thanks of downloading! :D
