So, since the last version of this aircraft i have inproved quite a bit. First, vtol 1 is to use advanced pitch, roll and yaw. Also 1 is to control were the nozzele points. Center- Vertical lift Up-Backwards Down-Forward Take of vertical then to fly slowly move vtol down. Slow down as much as you can before landing vertically. The % of thrust for safe landing(Vertically) is 65-70. vtol 3 is to move the wings up or down. If moved up will plane level it will lift up. Move down, plane goes down. Plane has to be level though. Any further improvements you do, tweet me @SketterPlayZ and make sure to check out my channel SketterPlayZ.
