Another not uploaded model. This is a partly fictional model of tu-104, as a later commuter derivative with tu-95 nk-12 engines for greater economy and better short-field performance. Such a project is based on tu-16 (which shared a wing with tu-104) unbuilt turboprop derivative, so such a modification of tu-104 might have appeared in late 60s. Though i have updated it with spoilers from my previous tu-104d-3 and an agjustable horisontal stabilizer (two main drawbacks of an original Tu-104).

This is a complete update of my previous planes controls, as i made a new system of controlling the spoilers. Now they have two predefined positions as inflight airbrakes (at AG3 with stabilizer control tuned to compensate pitch up more or less automatically) and ground spoilers (mated with thrust reversers at AG1)

Warning! Turboprops are pitch controlled! Thrust controlls the propeller pitch with engine governor maintaining the engine RPM. This way it is on nk-12 turboprops from tu-95 and tu-114. Thus:
1) Below 20% thrust they essentially work as VERY powerful airbrakes. Never drop below 35% thrust inflight unless you need to drop speed fast. 
2) optimal thrust for cruise flight - 70-75% at 28 000 ft.
3) optimal thrust for take off and low altitude - 90-100%

Controls
G - Landing gear;
AG1 -Ground Spoilers - spoilets simultaneously deploy full and underfuselage airbrake is retracted (if it is deployed by AG3 before). Use after touching down.
AG2 + VTOL slider - Flaps; (0% = Flaps retracted, 50% DOWN = takeoff position 100% DOWN = landing position) 
AG3 - inflight airbrakes - activates spoilers on wings on half elevation + under fuselage spoiler. If AG1 activated after AG-3 - it retracts airbrake below fuselage and deploys all wing spoilers full. 
AG4 - Aileron trim (VTOL Up- roll left, Down - right). If AG 7 is active (directional autopilot) - it also activates a gyro roll controll with VTOL for gentle turns
AG6 - Landing. Lights; 
AG7 - Ascend autopilot (Activate and set trim for ascend/descend. Can turn gently, than stabilizes
AG8 - Ground steering (sensitivity adjustment, when AG8 deactivated - steers to the limit, when activated - steers 5 degrees) Positions - AG8 - ON on Take off/Landing/In flight, AG8 OFF for the ground movements

Approach with full flaps at 40% thrust.
