The Yukikaze is not mine, I downloaded the Yukikaze from JoshuaW, the airplane source is from JoshuaW of course but, I changed the color to more like an Angel version and I extremely improvised the speed. Also, the fuel increased. The fuel won't drop even if you flew it for several minutes. Or maybe even more. Actually, when you normaly fly the Yukikaze, you would only achieve over 3000mph. But when you try to roll it upwards repeatedly you will achieve 7000mph. And that is the fastest speed this Angel could do. 1.)You should first press group no.6 to deactivate the air brakes 2.)Full throttle 3.)Press group no.1 to activate engines Then your ready to go. However, there is still another way to make the take off much cooler. 1.)Full Throttle 2.)Press group no.1 Wait until the flames or whatever its called turn longer and longer. 3.)Press group no.6 to deactivate air brakes
