A while back I posted a stock swivel jet VTOL plane (no infernal robotics mod used). It was a nice craft which failed to reach my original goal: achieve orbit with a swivel VTOL engine. The problem was my inability to dock in atmosphere to the main fuselage of a plane to gain access to more fuel. I do not know how but after many failed designs I got one model that docks fairly easily. I was unable to replicate it when trying to improve on this (my ultimate goal was a craft utilizing nothing but swivel engines). Introducing the Altamira MK4I (you can see how many iterations it took to get this working). Barely able to reach LKO, it can take off vertically and dock its VTOL engine to switch to horizontal mode and get just enough fuel to stay in orbit. This is a fairly difficult space plane to master. I only managed to reach orbit once. However with a bit of excess oxidizer left over, it can be reduced to save weight and increase the odds of success. Balanced by a single vector engine for VTOL, the craft chooses its own launch trajectory. Any attempt to wrestle the craft's yaw during the critical take off stage will result in the vector engine burning up the twin tail booms behind it. Shallow ascents are to be avoided if one does not want to burn up in atmosphere (except for when maximizing the scram jet momentum). This craft ascends steeply and quickly once it's set to horizontal mode so you can get to cruising altitude in no time. The horizontal latch can be doubled as a docking port to attach to space stations or other craft with narrow docking arms. After refuelling in orbit, it's ready to go on to other worlds (not tested yet). Despite 2 small docking bays that hold the VTOL engine & fuel, this craft doesn't do anything as it was designed for demonstration purposes only but that doesn't mean small science experiments can't be crammed inside. http://imgur.com/a/nNmOI

I saw an earlier work of a F35 swivel jet and thought I'd have a go at such a design. I never tried the F35 craft file so this was developed independently and I'm not sure if it works the same way. Goes from vertical to horizontal flight and back again. Engine rotation can be controlled when there's no forward or backward momentum. When RCS runs out or turned off, it becomes as a stunt plane, able to hover upside down while the pilot gets some fresh air outside the cockpit. Skip to 1:30 for the main part. Just another video showing specs, takeoff, and landing. [Download]
