Some qiuck sideproject for fun. My fictional civilian flying boat based on my Tu-124/134 replicas. Represents a hybreed between Tupolev Tu-124 and Tu-134 (wings and tail from tu-134, engines from tu-124, cockpit and landing gear from both) airliners and Beriev Be-10 early military jet reconaissance flying boat (general layout)

Has quite realistic functional landing gear, spoilers and wing shape. Double slotted flaps are my best creation. Can use thruster for maneuvers on water and ground (AG 8)

Controlls:

G - Landing gear;
Stabilizer (pitch adjustment) is adjustable with trim slider. normally about 1/4 up in level flight, but depends on speed, altitude and thrust.

AG1 - Landing parachute
AG2 + VTOL slider - Flaps; (0% = Flaps retracted, 100% DOWN = Flaps deployed)
On water: takeoff flaps 1/4, landing flaps 1/2
AG3 + VTOL slider - Spoilers (= Airbrakes, 100% UP = Deployed, 0% = Retracted, i added a compensating mechanism to the stabiliser, but still tends to pitch up the plane a bit, use on approach with partial deployment (pitch compensator works between 0 and 1/2 UP, above that it pitches down to push plane to the runway) or after touch down with full deployment)
AG4 -left engine
AG5 - right engine
AG6 - Landing lights;
AG7 - Nav. Lights;
AG8 - Water jets system for water maneuvers, S for brake/reverse, W for forward, QE for steering, works on the ground too)

Take off procedure - Trim 1/2 up, flaps 1/2 down, full thrust , take off speed ~ 170 mph, in right configuration the plane will take off by itself
Landing procedure - Full flaps, trim ~ 60% up, 60% thrust with full flaps, minimum safe speed 150-160 mph, use spoilers to control speed as plane reacts faster than to thrust. over the runway drop thrust to 40-45%, deploy spoilers 100% (AG3 + VTOL UP), parachute after touchdown if needed.
