But later on, a more advanced aircraft was developed, called the Kfir ("Lion Cub") using the USA licensed built J79 engine as used in the F-4 Phantom. The fuselage was adapted and some large intake scopes fitted. It retained 2 DEFA type 30 mm canons. The Kfir was in fact a new type now and first got the Martin Baker mk.6 ejection seat. 

The Kfir at first had no canard and first flight was Mid 1973. The C.1 was the first operational IAF Kfir and had no canard. The C.1 was upgraded to the "C.1 plus" and got a small canard. Also some earlier aircraft were "retrofitted" with small canards.  

The USA needed "agressor training" jets for the US Navy and Marines Corps and leased a version of the Kfir C.1 "plus", called the F-21A. It had a narrow chord canard on the intakes and strakes on the forward fuselage. The wing was unchanged with a straight leading edge with a slot. The first F-21A went to the USA was in 1985 and they were leased until 1989. 

Several Kfir versions were at IAI developed: the C.2 Kfir which got a much bigger canards, a wing with an extended outboard wing chord with a curve and the slot was not there anymore. The TC.2 is a longer nosed double seater trainer version.

Further development led to the C.7 with improved J79 engine and extra pylons/hardpoints under the intakes. Systems upgrades included a HOTAS cockpit with other display and in flight refuelling capability. The seat now was a Martin Baker mk.10 seat. Also various ECM equipment and slightly different under nose fairing. A large variety of weapons could be deployed including smart Laser Guided Bombs if the associated Pave Penny pod was mounted below the nose. Most C.7 jets were modified in the 1980s IAF Kfir C.2's.

The TC.7 is the two seater C.7 version. 

Several Kfirs C.2, often re-furbished ex IAF aircraft, were exported such as to Ecuador, Sri Lanka and Colombia. Also, during their careers, upgrades were often done. 

The C.10 had again different systems and upgrades mostly internal. The C.10 CE is for Ecuador with CE radar and the COA for Colombia. The TC.7 is the two seater C.7/COA version for Colombia. 

Another variant was used in South Africa with local development at Atlas with "Cheetahs" and others. There are substantial differences between the versions mostly seen in nose lengths. 

O.K.... back to the kits in 1/72 scale....
 

Update March 2018:  AMK has released a very good 1/72 kit at a very competitive price; if you can buy that one, that is the way to go!

Typical camouflage colours for the Israeli Kfir C.2 were: Federal Standard FS33531 sand, FS30219 brown, FS34227 green and lower surfaces FS35622 grey. Often yellow black outlined triangles for recognition were also applied. 

The Hasegawa kit no. 608" has not the Le Bourget scheme but additional decals for a grey camouflaged IAF Kfir C.2 markings (with Fed.Std FS 36375 overall and FS36320 at darker areas) as well as the scheme (2) above. 
.
(Please note that when your kit is very old, the Hasegawa decals tend to crack and break up in water. In that case cover these with decalfilm like from MicroScale). 

The kit cockpit is very simple but there is a "tub". But there is a gap in the rear bulkhead that needs closing up with plastic card.
The exhaust is very undeep. Stores includes pylons and 2 outboard wing fuel tanks, a central fueltank and 2 "Sidewinder" like missiles stated as Shafrirs. The main wheel bays are a bit undeep and not detailed. The nosewheel is integrally moulded as one part with the nose gear strut. 
.
But there is a separate entry ladder though a bit thick and the canopy and windshield are separate parts.

The kit shape and dimensions looks good. A straight out of the box assembly can be done but some modellers may prefer to inscribe the main panellines which are raised in the kit. I did not bother as the model would get a green-brown camouflage making most of the panellines less obvious. 

Some parts were prepainted like the intake insides white. 

Here the outboard wing leading edge extensions are well seen (these were not there on the very early Kfir C.1 and F-21).

There is no detail in the main wheel bays so you may add some bits and stretched sprue to suggest a busy wheel bay. 

This old Hasegawa kit fits surprisingly well! Only some tiny spots of filler is needed but the fuel tanks needed more filler. The fuel tanks also need putty besides some areas at the intakes. At the lower sections, gaps need to be closed as well. 

The trailing edge flaps edges, ailerons edges and rudder were cut in with a razor saw, this looks much better on any model.

The results after filling and sanding, canards not yet fitted obviously to make airbrushing easier. The upper spine antenna was cut off to make sanding easier, it will be installed back when appropriate for the version later made from thin plastic card. 

Here it is seen that the main wheel bays are rather barren, I added some details from scrap using stretched sprue, metal wire and bits and pieces.

The nose wheel and gear leg are one part and also bit too crude. The wheel and leg were separated with a razor saw and a new "fork" made from a piece of etched metal. It improves how it looks. 
......
The windshield was to be set onto the model with white glue. Masking was done as well.

Not a lot of pylons were installed on this model.

A nice colour scheme was selected and a few Hasegawa Kfirs were to be made..... 
 

The first Hasegawa kit was made as a C.7. The real Kfir C.7 could be fitted with extra pylons and had modern systems in the cockpit (See notes above). It had a camouflage pattern. The ISRA book shows plenty of detail and the rear of the Italeri box as well for the scheme.

Colours used were acrylics that were airbrushed with the Harder Steenbeck  (starting first the lighter colours):
Lower surfaces grey FS 35622 using Gunze Sangyo 314 ;
Light brown Sand FS 33717 using Revell Aqua 88  ;
Green FS 34227* using Gunze Sangyo 312 ;
Tan brown FS 30219 using Gunze Sangyo 310 ;

*NOTE: later on I found out that on the Kfir the Green is not FS34227 as seen of F-4's and F-16's but  FS34424 for which RAF colour Sky Type "S" is an approximation. Also, on the C.7 the blue in the IAF roundel should be slightly lighter blue than on earlier jets. 

Other areas were hand painted like the vertical tail top and some smaller panels and edges black. Masking was done with low tack masking film (like from Revell). 

After colours were applied, time for the decals. But, use the decalling technique to prevent "silvering". A gloss undercoat is really needed. The decals were a mix of the kit and others like the Italeri kit (also to be built). Look at photos as there are slight variations on the real Kfirs, for eaxmple also in antenna layouts. The walkway and arrow marking decals take some care here. 

The vertical tail markings came from a Classic Plane TC.2 conversion kit decal sheet (also to be made). 

Decalling done....

....and after decalling done the details like the gears added. Some hydraulics were added made from thin metal wires fixed with super glue. The barren wheel bays got some extra details from bits and pieces and were painted "off white" as well as the insides of gear doors. Below also the smaller air intake end exhaust scoops are seen added from scrap. The canon ports were painted black.

Inside the cockpit details were added like a HOTAS HUD display with which the Kfir C.7 was fitted. And a Sidewinder AIM-9B missile from the Hasegawa kit was set below the wing on the outboard pylon. Pylons are in the kit.

The model got a semi-gloss coat to get an even sheen and protect the decals with the usual technique... . 

The seat from the kit got some straps and ejection handles painted yellow-black from thin wire and details. Canopy to be set open was fitted after it got two tiny mirrors. Various tiny probes and pitots were added on the nose; the big spine antenna was not needed for this particular aircraft. That completed this IAF model.  

  ISRAEL
............

[ area: 21,000 sq.km | population: 9,7 million | capital: Jerusalem | GDP 55,000 USD nominal ]

The Israeli Air Force (IAF) got many Kfirs for air defense and other missions and of various versions. They were widely used during various conflicts with over 200 Kfir jet deliveries.
