The XE-lambda is an interceptor capable of both low and high speed flight.The foldable wings allow it to switch between a steady 500~600mph to a maximum of 1500~1600mph within a few seconds.Through the activation a third engine this transition is both smooth and effective while also allowing it's deactivation to preserve fuel and allow for lower speeds without messing around too much with the thrust.The wings also help out by providing great maneuvering capabilities when extended.All these factors along with 6 guardian missiles,4 interceptor missiles and 4 front MGs make this one of the best air superiority and interception aircraft (I've) ever made.Control group 1 activates the third engine,group 2 activate directional lights.the wings fold through the bar on the side. ONLY MOVE THE BAR TO EITHER THE CENTER OR TOP,NOT BOTTOM.KEPPING IT BETWEEN THE 2 POINTS ALSO DOES NOT HELP IN ANY WAY
