My entry into the landscape challenge. Here's how it works:
Land: Press 2 and VTOL down to fold the wings. Throttle up to no more than 20% and use yaw to steer.
Air: Make sure 2 Is activated and return the slider to center. Throttle up to 100% and pull up. The primary wings will flex but for some reason never break off. When you get in the air, deactivate 2 and, if you wish, activate 1 and VTOL down to rotate the vertical stabilizer into position. Put gear up.
Water: To land in the water, throttle back all the way and gently drop down into the water like you were landing on a runway. Use the brakes to slow down. Activate 1 and 2 and VTOL down. Throttle up however fast you like, but I don't reccommend more than 50%.

Have fun exploring the island!
