Realistic flight in Minecraft has never really been implemented. Even the elytra doesn’t take into account true aerodynamics. Minecraft Flight Simulator aims to change all this, by introducing planes that handle like actual planes! To do this physics and aerodynamics is used, taking into account thrust, drag, lift, prop pitch, and much more. Controls are also tailored to provide a simpler means of controlling planes than the current standard of ‘mouse-yoke’, which allows you to look around as you fly. You can even customize your planes by giving them different propellers and engines, which affect their flight characteristics.
For a full list of controls and features, see the form page. Please direct all posts, inquiries, general comments, and PMs here as well, as I don’t check the Curse sites often.
