Taj avion što liči na MiG-21MF je, u stvari, njegova kopija oznake J-7III. Kinezi su od Egipta dobili MiG-21MF i onda ga iskopirali. Spolja je gotovo identičan sa sovjetskim avionom. Napravljeno je vrlo malo tih aviona, nekoliko desetina primjeraka.

Dali su J7 i produžili ili samo izgleda duži od MiG 21?

Istotako me zanima, koloko je to bila dobra kopija? Mislim na to, da posle par nadgradnji (svog razvoja) došli su do točke, gde su ga razvijali u skladu sa svojim potrebama, a Sovjeti sa svojima. Tu imam u mislima MiG21 Bis i kineski ekvivalent.

Hvala

Što se dimenzija tiče nema mnogo razlike.  J-7 je malo kraći i ima malo veći razmah krila.
A što se tiče toga koliko je bio dobar... prve verzije su bile proste kopije sa svim manama i vrlinama originala. Najraniji modeli možda i lošiji od MiG-a. Dok je sa kasnijim verzijama sasvim druga priča, npr. kupci verzije F-7M tvrde da je avion za oko 40% efikasniji od MiG-21. Pa ti sad vidi...

Imam pozitivno iskustvo sa Kineskom hi-tech opremom (prenosnom) i mogu reči da je za to, koliko košta odlična.
Recimo Njemačka Siemens oprema, košta 100.000 €, dok Kineski "Siemens" 40-50.000 €. A funcionalnost je identična. Je da je kod Njemačkog u detaile sve razračeno (tu Kinezi malo zaostaju) ali nisu toliko lošiji koliko su jeftiniji.

Verujem da je i kod ostale hi-tech opreme slično.

Možda se nismo razumeli, Bangladeš nije imao J-7III, jer ta verzija nigde i nije izvezena.
Glavna vizuelna razlika između originalnog Miga 21 MF i kineskog J-7III je u kućištu padobrana koje je kod kineza nešto veće, okruglog preseka i sa polukružnim poklopcem, dok je kod rusa manjeg preseka onako 'dvostepeno' i sa špicastim poklopcem. Druga razlika je kod kineza i u nešto drugačijem dielektriku na vrhu repa.

Na ovde okačenoj fotografiji "J-7_49.jpg" je bangladeški MiG-21M sa serijalom 7006, inače avion prizveden u Indiji u HAL fabrici (serijali 70XX). Obrati pažnju na kućište padobrana.
Bangladeš je imao i originalne MF-ove koji su imali serijale sa 72XX.

Da ne bude da spamujem temu evo par slika J-7III i od mene Smiley

Ovo je fotografija jednog od originalnih Migova-21MF koje su kinezi nabavili i koristili za ispitivanje i kopiranje, nosi broj 150

J-7III sa brojem 151 na nosu je prvi prototip

@airsuba, u pravu si, nismo se razumjeli. Ti si pisao o jednom avionu, a mislio na  sasvim drugi. Smiley I upravu si za indijski MiG (tip 88) sa oznakama Bangladeša, moja greška.
