ive done the movement stuff before… i had a full character rigged that moved around with an xbox controller it was relatively straight forward. The character even casted a fireball… had running animations and jump animations and loops… blendspaces… and was able to move from level to level with a predetermined location that teleported her to the new level.
All of that i did in like 2 days. im a fast learner. But while i am interested in the VR aspect of this game i want to develop… i am not even looking into that aspect of it yet… i am doing exactly what you are saying… trying to jsut get the plane i have to move is a challenge right now. It does not react to WASD at all… and if i follow the tutorial documentation about the “buggie jeep” it tells me to set wheels to kinematic but that breaks everything.
Right now i am stuck on getting this plane to even move forward… it has 3 wheels and i dont know if thats causing problems. the wheels kind of “free roam” in any direction as opposed to the typical wheel movement one would expect… such as … moving a vehicle to the left without turning and the tires go end over end in place… as if they were a sphere but dont look like a sphere… all 3 tires do this… and it doesn’t help that my front tires are angled out at like 45 degrees. 
im assuming that im going to have to compensate for this but i dont know how.
i am looking for the basics… but all i really find tutorials for is “simple car UE4” stuff… like one body and 4 wheels… which i CAN do… i dont need to know how to introduce a car… i need to know how to introduce a car with moving parts… like a tutorial on a car that had an operable door and trunk would be nice… but will it show me how to rig it? do i rig it in the modeler or rig it in UE4… do i build the animations in the modeler… or do i build them in the animBP… how do i make an object on a vehicle interact with another object on the vehicle… such as … turning the engine on with a switch or key… how is that modeled… is it a completely separate mesh that is imported separately or is it ok for the switch to be attached to the original mesh.
im where i need to be in terms of learning the process… i just cant find the correct material to help me learn the steps just past “the basic introduction” type material.
