Tupolev Tu-104A 1956

Finally a new model)
Tupolev Tu-104 was famous as a second jet airliner in the world to enter service and the only one in the air in 1956-58 (as DH Comet was withdrawn from service) and notorious for having the worst safety record in Russia and probably in the whole world at 16 hull-losses of just 201 airplanes ever produced, many with everybody on board ending dead. As communist party was never known for admitting their fails and due to most crashes were partially blamed on pilot error, the plane was not withdrawn from service like Comet.
Actually the problem was not really in lack of skill or negligence of pilots and designers, the plane was simply very difficult to fly. Chief designer Andrey Tupolev, one of the most famous russian aircraft designers (and a student of Hugo Junkers) was given only a year from start to mass production, so he decided to simplify plane a lot and used engines, avionics, wings and landing gear from a Tu-16 medium bomber. The plane appeared to be reliable as AK-47 technically, but lacking spoilers (or airbrakes of any other kind), with no adjustable stabilizer (thus making it very sensitive to weight distribution, which was not a problem on a bomber with payload in bomb bay directly in center of gravity), ineffective single-sloted flaps and virtually no automation, no hydraulic assisted controls (on a 75 tonn heavy mach 0.9 jet!) and facing busy urban airports with steep descent patterns, it often overshoot runways (though as it was built like a tank, only the pilots careers suffered usually). Furthermore, it appeared that elevator size was insufficient, so a plane with wrong payload distribution or facing updraft winds, became very susceptible to stall. This was only understood and corrected after 4-5 crashes... Luckily, later Tupolev planes (i.e. Tu-114, Tu-124/134), though having much in common in overall appearance and air-frame construction, received all the needed technical features and where known to be a lot easier to fly.

Has completely functional Flaps, Landing gear, Nav. Lights and some cameras. It is a 1:1 scale and weight replica. It flies quite realistically except for being a remarkably bad glider...

Controls:

G - Landing gear;
Trim normally about 1/4 up in level flight, but depends on speed, altitude and thrust.

AG1 - Landing parachute (activated after touchdown)
AG2 + VTOL slider - Flaps; (0% = Flaps retracted, 100% DOWN = Flaps deployed)
AG6 - Landing lights;
AG7 - Nav. Lights;
AG8 - Ground steering (sensitivity adjustment, when active - steers to the limit, when deactivated - steers 5 degrees, deactivate on takeoffs and landing, activate for ground maneuvers only)

Take off procedure - Trim 1/2 up, flaps 1/2 down, full thrust , take off speed ~ 170 mph.
Landing procedure - Full flaps, trim ~ 1/8 up, 70% thrust with full flaps, minimum safe speed 140-150 mph, over the runway drop thrust to 30-35%, deploy parachute (AG1) if needed.

Too heavy for mobile devices...

p.s. coming soon - Convair CV880, as it appeared to have very close dimensions, same fuselage diameter and wing form and very similar cockpit)

    @JayJoeCc Thanks! But i found some mistakes (for example missing left cockpit wall), and some points to improve ( finally got idea how to make sychronised gear doors, plus made better eailerons). Stay tuned, probably will re-upload in several days

    @Supercraft888 @vonhubert yeah... It wasn't just Cr I said, I argued that it wasn't that bad. I haven't said a bad word since... I think?

    No, it's not that I dont like the f-word, it's because last time someone put the f-word they were banned, and I DO NOT want that to happen

    Gosh I didn't know people could get so up an at em' with one little F. Love the plane bro, sorry about your struggle with humans, just remember. Humans are very emotional creatures and need everything to be watered down for their personal "wants" not needs "wants"
