Built for the Ultra heavy seaplane challenge. And it's by no means short of "Ultra Heavy". Aircraft is defiantly one of the more exotic ones I've made and includes some crude thrust reversers along with tilting wings to aid waterborne takeoff and a few sets of fold away floats to aid balance while in water. obviously, the shear size of the craft can cause problems for less capable devices and low level flight can cause wing twisting at the motor joint. Controls: To deploy floats, use activator 1 in conjunction with VTOL slider. To engage thrust reversers, use activator 2 in conjunction with VTOL slider. To adjust wing angle for waterborne takeoff, use activator 3 in conjunction with VTOL slider. Don't tilt the wing too much as it can result in uncontrollable pitching of the aircraft and stalling.
