Hey hey hey! Just for fun, here's a rather heavy seaplane. The way in which I build my planes is inherently lightweight, so this is not as heavy as what one may consider an "ultraheavy" plane, weighing in at 30,000 lbs. Anyways, this is a remake of an old design I made when the floating blocks came out, just revamped with new parts like the Fuselage block, the new Engines, and new Large Landing Gear. It takes a while to get out of the water, but at about 120 mph it should get in the air. For some reason in order to maintain a straight line in the water you need to constantly yaw right lightly. Be wary of stalling or spinning out at low speeds right after taking off!
