Only one minor comment - the two intakes just ahead of the nose undercarriage door - they're offset to one side :

Man, you've got me all worked up about doing my Revell (new / Italeri) 32nd IIIE as a Cheetah C - very doable indeed. Thanks for the inspiration :smt023

Regarding the intakes, one can see the the subtle convex curve on the right intake.

Hi Snoop

Perhaps remove the above image. Rather use hyperlinks when referencing images on Airliners.

I will post a image of my Cheetah to illustrate the point.

Hi Snoop

Here is a topview of my 1:48 Cheetah I built a while ago.

The red line indicates the curved intake. Its a very subtle detail, probably not necessary to add its just that Mistral was asking about it.

The apex on my model should be perhaps a bit further back.

The Kfir had bigger intakes for the J79 which has more power that the Atar 9K50.

There is a brief discussion about the intakes on this thread:

hi

sorry :oops:

I understand now about the curved intakes #-o , at this stage of the build , I will let it as it is , too risky , too tricky ..... the hump on the back is done ,. as well the "pipe " ahead the front bay moved

Hi Snoop

No problem. There is limited benefit in doing work on the intakes at this stage. I also won't mention the square fuselage :twisted:

I am reminded though of how many changes need to be made. The Cheetah C was a very unique aircraft, I don't think there is any other aircraft that has been as heavily modified has the C.

The rule here is pictures or it didn't happen! :twisted:
I agree with you and Mars, such a tiny detail risks too much to go wrong. Next one... :wink:

I actually never noticed the slightly larger intakes on the Kfir/Cheetah C. :shock: I always assumed they increased their internal ducting to allow a greater air flow rate. In hindsight simply enlarging the air intake should have been my first guess... :lol:

Air intakes were cut back/enlarged at the time of fitting the single piece windshield.

I think you are referring to the Cheetah D's upgrade to the 9k50 which included the single piece windscreen. The C's were delivered with the single piece, plus built on Kfir air frames meant their intakes were sized for higher airflow any case (J-79 vs 09C on a base Mirage 3). They cut the intakes back which also produced the curved splitter plate (which does make me wonder what on earth the SMR-95 team did to their Cheetah :shock:) . But we are going off-topic here. :lol:

Thanks Mamba, you're correct. I was thinking of the D. :oops:

Good debate. The Mirage IIIR2Zs which had the 09k50 fitted had the intakes cut back with the scalloped splitter plate. The Cheetah D's modified to take the 09k50 engines has the same scalloped splitter plate. So for the Cheetah C, I've heard that these were converted from ex-IDF Neshers and not Kfirs (ref. W. Brent's book "Cheetah - Guardian of the nation"). The Neshers were copies of the Mirage 5 which had the 09C and not the 09K50. So then, to convert Nesher airframes to take a 09K50 wouldn't have been a problem as the engine was essentially the same with updated internals for higher flow rate / power. But why then the absence of the typical scalloped intake splitter. And that doesn't explain the odd upper fuselage hump....I'm open to correction on the Nesher aspect....

Hi Malcolm

I think you are referencing the chapter on the Cheetah B which refers to the Nesher T. The chapter on the Cheetah C refers to Kfirs.
