This is the opinion of the experts, as reported in Wiki the Pedia:
"A prototype version of the Qaher-313 has been portrayed to have test-flown at some point before the presentation.
[9] According to the head of the design team two sub-sized models have been created and tested. One of the models uses a propeller engine while the other uses a small micro jet engine.
[10] The models were shown in a video clip (along with descriptions by the head of the design team) the same day.
[11] According to
Haaretz, the "blurry video published by the Iranians purporting to show the Qaher 313 in flight seems to show not a manned fighter jet but a small radio-operated drone."
[6]"
Flight Global noted that the Qaher-313 resembles the
Boeing Bird of Prey prototype, but with a more faceted design similar to the 1970s-era
Lockheed Have Blue that was developed into the now retired
F-117 Nighthawk. Flight Global also said, "given the apparent small size of the aircraft and its single engine design, the Qaher 313 could be powered by reverse engineered variants of the General Electric J85 turbojet that Iran is known to have in its possession." Iran has
General Electric J85s as a result of old
Northrop F-5s in its inventory.
[8]
Israeli experts doubt the Iranian claims, saying the fighter presented was nothing more than a "very sleek plastic model." They note that the canopy appears to be constructed of "basic plastic," and its engine air intakes are unusually small. They say it gives the impression of plastic parts pasted to an old flying platform. The cockpit and ejection seat seem real, but the Qaher-313 displayed seemed too small to be a capable fighter. Video footage showing the plane airborne could have been a radio-controlled model aircraft."
