So this plane does require the beta update if you have the update I will tell you how to use the craft. To rotate the rudder so it's upside down (this gives the ability to control the boat form) press activator 1 and roll the craft until the rudder is exactly 180 degrees opposite when you started, to hold it at the position deactivate activator 1. Skipping to activator 3 ( to turn the boat ) press activator 3, leave on to turn, deactivate to hold in position or stop turning, use rudder controls to turn. To rotate wings use activator 2, use roll to turn wings, I know it is hard to turn wings or rudder in midair because of roll but all you need to do is climb to a high altitude and do the roll. And p.s. if rudder is upsidedown in midair elevator flaps are inverted.
