Easy FoolProof Helicopter (Survival Friendly)

Basic, easy to understant helicopter. Has no addons except for the aeronautics itself. Set W - f1:copper trapdoor, S - f2:copper trapdoor, A - f1:symmetric sail, D - f2:symmetric sail, SHIFT - f1:redstone accumulator, SPACE - f2: redstone accumulator. W-S to move forward and backwards. A-D to rurn around, and SHIFT-SPACE to add or reduce throttle, set throttle lever to 12 (or 13 if you know what are you doing). Flying on this heli is hard to fumble, unless you are TRUE dumbass. Copper is only meant to make mass center work in our favor, you can remove all of it ( and seats) and make it into just the helicopter core, which you are free to use for your own build. (if you are willing to get into mass centre shenanigans)
