The main difference between J-7I and MiG-21F-13 is MiG-21F-13 has only one GSH-23,but J-7I got two.

F-7A is export version of J-7I,with more power WOPENG-7B (WP-7B),and deceleration parachute compartment position moved.

J-7II is update version of J-7I.Deceleration parachute compartment position moved as F-7A.And cockpit open form back,not form front as MiG-21F-13.And got HTY-2 ejector seat.Also WP-7B as F-7I

F-7B is J-7II's export version.Updated western A2A missiles such as R.550.Better ejecteor seat.(?)

 

F-7I :

 

Arbania (12)

Tansania (16)

Egypt (60)

 

F-7II

 

Iraq (90)

Sudan (22)

Egypt (60) Updated from F-7I

 

 

J-7I---------->F-7I

J-7II---------->F-7II

FM = FlightModel ?

 

 

Yes FM = Flight Model :biggrin: .

 

Thanks a lot for these insights Erwin. That means I won't have too much work to convert my 21F13 FM to Jianji-7 FM :biggrin: :biggrin:

 

Ok lets sum up:

 

J-7I = MiG-21F-13 but with 2 NR-30 or GSH-23

F-7A = J-7I with more power WOPENG-7B (WP-7B) and new dragchute compartment position.

J-7II = J-7A with HTY-2 ejector seat.

F-7B = J-7II's export version.Updated western A2A missiles such as R.550.Better ejecteor seat.

2 NR-30 is right.

 

And J-7II is very very close to F-7A

May I ask what's the difference between J-7II/F-7II and the F-7M Airguard? :dntknw:

 

I read somewhere that PLAAF didn't use a domestic version of F-7M, is that correct? If so why? :dntknw:

F-7M is a upgrade version of F-7II,with WP-7BM engnie(export version of WP-7B).Piltot tube moved to right on nose.And F-7M got 4 under wing hardpoints can loa with PL-2,PL-7,or R.550.ect[Maybe AIM-9J/L/M?]

Within a 956 HUD(used in Harrier?),and a WAC from GEC.Marcni,a new ranger scale radar

 

Why PLAAF have no F-7M?

 

1,We must know that...PLAAF always export a aircraft better than homeuse one Before 1990.

2,First flight of F-7M is in 1983,and in 1989 we got Flankers and J-7E and update project of J-7H or more.

3,F-7M,the "M"is the first word of "Mao Yi" in chinese,which means export. So F-7M must be a Export noly aircraft.

Thanks for the info Erwin. :good:

 

So it sounds like the J-7II/F-7II can only be armed with 2 IR A-A missiles instead of 4, right?

Thanks alot F-16CJ.

 

For the ammunition, can you confirm that it is 60 for each gun (2 x 60) and not 60 for both (2 x 30) ?

Right

 

Thanks Erwin for the confirmation and also to F-16CJ for the additional info.

 

It looks like someone or some group has made a F-7 Skybolt mod for MSFS 2004:

I think it would be cool if one day we could also have a comparable mod for the F-7M Airguard or F-7P for SFP1.

I have read somewhere that th chinese mig-21 has a better agility especially in the late modells of the 80's

Ah, no.. The wing and stab values are exactly the same as the MiG-21, and the slight boost in power resulted in less than satisfactory results. You're confusing it with the J-7E and later varients, which sport a compound-delta wing, and that modification did improve the aircraft's agility. Source: http://cnair.top81.cn/F-7_J-7_J-8.htm

um, yes I overread it, sorry J-7E and later... would be cool to see those birds in such a quality like the 29, but this will be a dream ;-)

 

Well, the MF MiG-21F-13 model could be redone without too much trouble to incorporate the extended compound-delta wings. The 'pit would be more of a challenge, as Mago is busy with other projects at the moment.
