I wanted to make one of these almost since I first got the game but it didn't work out. but now I have created the model that does it right. to VTOL of the ground throttle 65% 1 then pitch down then Wait to about 1000 feet then pitch up VTOL forward halfway after leveled out then the rest of the way but still keep pitching down. land takeoff VTOL halfway forward then the rest of the way. mow I did put some floating blocks in to assist water rescues but that does not mean it is a sea plane but in order to float you must go to the water surface and throttle to 53 percent and it will just sit there has jundroo and tiny suport. if you have any of plane or car then let me know and I will recreate it!
