Box Tilt Wing VTOL Supersonic Airplane

This craft is 100% stock and is capable of vertical / horizontal takoff, landing and speeds of just about Mach 4. Also it uses a box wing design.
How to use it:
Apply brakes, press action group 3 (maybe twice if nothing happens), press spacebar (the explosion is supposed to happen), switch the vessels (this design splits this craft into 2 vessels so this is mandatory), tilt the tilt wing *duh* to approx. 90° and start the engines at Max throttle,
After the vertical takeoff switch the vessels to start the main engines using the action group 2 and retract the airbrakes and the gears, level the wings slowly to align them with the docking ports. After doing the actions I listed you should be now flying horizontally.
To accomplish a vertical landing:
Slow down to approximately 40m/s using the airbrakes, press action group 1, switch the vessels and start controlling the wings and throttle to complete a vertical landing.
Action groups:
1: undocks all the docking ports,
2: toggles the engines
3: extends/retracts the assisting gears (they help with stability on the ground during horizontal takeoffs/landings
If you liked this craft, please, like and favorite it, this took me ages to build!
