Another thing to say. Group 8 are for emergency engine cut down, so you wanna keep it on. Group 4 are for the propeller engine in the front, don't open that engine too long or it over speeds and explodes. Group 1,2,3 are lights, group 6 is for parachute, group 7 is for slowing on ground, do NOT open No.7 until you are on the ground.
