Question: How do you control the helicopter and seaplane in game?
Answer: The control listed below are presuming the default control configuration has not been altered ingame
Use brake and accelerate to move the helicopter down and up. Use the number 9 key to tilt it forward. You need to keep the helicopter at a slight angle forward to get forward momentum. If you keep holding forward the helicopter will try to perform a forward flip so this needs to be constantly adjusted
To control the seaplane use brake and accelerate to move the plane faster or slower. Use the number 9 key to tilt it forward (nose down) and the 6 key to tilt it backward (nose up) Keep 6 held down while accelerating on the water to take off.
These keys can be changed for both the helicopter and the seaplane in options>>controller>>redefine controls
The controls in question are look left, look right, turret + lean up and turret + lean down
