Something you dont see very often in simple planes is a coast guard plane, this one comes with many systems to help the plane continue flying in very bad weather as well as an inflatable life-raft that can be dropped from the plane. G1 is to switch on the first prop set and G2 is to switch on the second prop set (the reason for this is so that you can balance the plane out to continue flying if one or two propellors break off) G3 is nav lights, G4 is emergency parachutes for when you land a little to fast, G5 is gyroscope which helps keep the plane at level flight and helps with takeoff and landing in heavy winds, G6 is to drop the box containing the life-raft, wait till the box reaches the water and then press G7 to inflate the life-raft. Hope you enjoy :)
