First off let me say hello, There are several ways to make vtol aircraft some easier than others depending if your using mods. These tips are good for stock builds. Have all of your engine point down straight and control your aircraft with small tilts in the direction you wish to move this is the hardest but most fun option. Be warned at least 4 engines is needed for this design to be stable. The second is again 4 engines with then angled slightly off center. So the two at the front point forwards with the engin at about a 35-45 degree angle facing the nose and the dame for the rear engines towards the tail. Stick a 5 engin on the back in the normal place to move forward. This is the design I have used in the mox industries thread in my Sig. The 3 is a small light craft with just 2/3 engines. 2 on the end of the wings pointing down ans one on the rear of the plane for forward momentum. I hope this helps.
