    Is this the tech that makes VTOL possible?
    fearlessly exposing my ignorance here haha

    The pilot is standing on the ground, that's a model airplane.

    It is amazing what they have done with model jets over the last 20-25 years.

    The maneuver is a " Pugachev's Cobra". It is done with a favorable thrust to weight ratio, sufficient energy, proper inputs on the control, and airfoil features such as leading edge root extensions that help fly the aircraft through normal stall points.




    The F-22 can do a cobra plus the flip as well.

    No, the VTOL aircraft have a different system with more thrust outlets and intake system. But VTOL aircraft have adjustable rear nozzles and use thrust.

    I'm not even sure it's a model airplane, it might be a model airplane simulator.

    The Full Size Mig-29 (introduced way back in 1977) does not have thrust vectoring. Some of the Sukhoi planes do, and the F-22 does.

    The Mig-35 was just introduced in 2019.. it was planned to have thrust vectoring but it was then removed.

    Thrust vectoring sometimes seems like a party trick. Makes for killer airshow demonstrations but it doesn't sound like it actually has accomplished much in air combat.

    Soviet? I thought they were back to being just Russia. (which would be a great name for a band--> Just Russia)

    crazy piloting.

    It has severe limitations due to physics, the aircraft loses a lot of energy. Dangling in the sky against modern aircraft with relatively equal quality and numbers plus helmet cued infrared missiles will get one killed in a hurry.

    Thrust vectoring was not a required specification by USAF for Gen. 5 or 6 fighters for a reason: after years of testing it they realized it is not that important. The F-22 has thrust vectoring up and down, but not side to side. It was not a requirement by USAF. It is a spice, not a staple because of energy loss.

    As they say in aerial combat: Speed is life, but rate kills.

    That MiG-29 is in the hands of an exceptionally skilled pilot. what the Russians call sabres, the fairings forward of the wing root gives the plane the additional lift in the form of body lift for low speed maneuvers. Holding the aircraft in the vertical and being able to slide tail first toward the ground is the result of incredibly powerful engines in after burner combined with stable aerodynamics. The MiG-29 was designed before the Russians mastered the fly by wire technology necessary for the metastable aerodynamics of modern aircraft. One other thing I noticed in the video is the absence of a soot trail. I’ve seen MiG-29 flight demonstrations twice. The Russians also seem to have mastered the high temperature combination necessary to maximize power and efficiency. The added power makes possible now what the plane couldn’t quite manage in the 1990’s.

    All I can think is that is probably a pretty expensive trick to learn...every time you get it wrong, you’re buying a new RC plane!

    not as expensive as real jets, obviously.

    Now that I’ve thought about it, it seems like holding a car on a hill with clutch/gas manipulation.

    Yup....it's an RC model plane. Click on the video and go to the YT page...the name of the page is 'Essential RC'.

    It's an RC model......not a real plane.

    Based on the thread title i thought this was a thread about a banned subject... I was pleasantly surprised and quite enjoyed watching that RC plane doing its thing!

    It doesn't even look like an RC plane, it looks like an animation. The smoke looks pixelated to me and dissipates so quickly, then when it bottoms out while landing at 5:50 there is no sound of an impact much less the lack of engine noise during the entire flight.

    Cool, but not as cool as Rogue Squadron on N64.

    Thrust vectoring is one way for VTOL.

    the Hawker Harrier / AV8A/B is a classic example - it could direct its thrust more than 90 deg between pointing down or pointing backward. It uses a lot of fuel to take off vertically so most would use a short runway or ramp to help get airborne. Our pilots discovered they could do it in high speed flight to stop in the air so that any chasing plane would overshoot. VIFFing they called it.

    The mig model in the clip uses vectoring to increase its manoeuvring ability. Pushing its tail around tighter corners - but same principle.

    Rockets vector their engine thrust to steer as they ascend the same way.. like steering a wheelbarrow or balancing a stick upright on your finger.
