First, VTOL controls movement. The VTOL nozzles can spin twice as much as a normal nozzle. Giving you thrust downwards even when you flip over. You can go into the air by moving the VTOL as needed. Throttle up to 27% and take off. Use normal controls in the air. Just be careful on the way you use them. You have to be careful when landing. And think about where you are trying to land. Use the yaw while in the water and a maximum thrust of 20%. Use VTOL as needed. It takes a bit to learn it but it is very easy. It also has fuel for days. It is also very good at climbing mountains. Just use the thrust when needed. When just cruising around, use a thrust of about 10%. This thing is powerful. Have fun.
