This is the first new enemy aircraft added into VTOL VR. You will need to install the Custom Assets Mod from Cheese, then extract the zip file into the mods folder, or into a folder for your CSA assets.
Then add the aircraft into your scenario via the mission editor. It should be possible for it to start on the ground or in the air. The mirages will engage.
They have their own engine and aerodynamics, with some simple setups. This is the first of many aircraft I hope to build. The model is pretty poor and has lots of issues but it's the first prototype. Have fun!!
