Here is a small project I have been working on.
A Bristol Aerospace CF-5C "Frozen Freedom Fighter". It was an indigenous Canadian design to solve a CRAPP(Y) problem.
1/72 ESCI CRF-5A with Hasegawa F-20 nose and wings.

Noice !!!!
Got a couple of those Esci CF-5's in the stash, and a couple of the Italeri rebox
Did I ever mention I had the opportunity to work on a real CF-116, one for The Military Museum in Calgary. It was to redesign the mounting pole and the fuselage was in my brother's workshop yard for nearly a year.
This one below - 116707.
-
That will get some double takes! Nice work!! :-*
-
Beautiful concept!! I'm certain Northrop Aircraft would be envious.
-
Cool!
Wonder if it could use an extended avionics hump (like the Scooter or MiG-21) down the spine and some additional antennas on the tail and fuselage to "update" the look a bit?

This is a great idea Paul. I'll ensure my next F-5/F-20 build gets this.

Some more inspiration:

Really is no end to the tinkerings that can go on an F-5
-
Excellent concept Carl! - the ultimate CF-5 upgrade :D

Yup. And then, as with the Bristol Aerospace reman programme, threats of lawsuits would follow ;)

Wow that's looking sharp already, Mr Gimper!
Looking very much forward to this one.

Lots of progress. Only the canopy and Sidewinders are missing. Had to use the CF-5A centerline drop tank due to the location of speed brakes. Pleased with the fuselage/wing seam.
Paint going on this week.

Yeah! :smiley: :smiley: :smiley: :smiley:
Nicely done Carl
-
It's looking really good! Is the landing gear from the kit - it looks like a naval aircraft gear or beefed up to land on unimproved fields.
-
Looking good.
-
The gear is kit stock and yes, I too was surprised by the design and size of the landing gear.
-
The diameter of the main u/c legs can't be much more than 4 1/2" (115mm), the wing is only 5 3/4" deep where the u/c bays are

Spoiler alert. The upgrade program was called CANOE. Can't get more Canadian than this.
And the subsequent Northrop lawsuits? They were dismissed as it was determined that Northrop could not find Inuvik on a map nor spell Tuktoyaktuk. So they had no business meddling in Canadian Arctic Sovereignty issues.

It is no secret that I have been pining for quite some time the return of FS16515 Voodoo Grey. Well with a big thank you the Fairy Paint Person I have some in hand.
And it is no-longer Voodoo Grey but rather Air Command Grey. With paint and Lightning Bolts in hand, here is my first build with these two items.
But first why the CF-5C?
Most non-Canadian folks may not know this but Bristol Aerospace in Winnipeg, Manitoba held the contracts for DLIR (depot level inspection and repair) for both the CF-5 and CF-101. This is a complete tear down and rebuild of an air frame. And apply upgrades as required.
In early 1981, the CAF learned the CF-18s were not going to be delivered as per the original schedule. There were some serious technical issues with the meeting the CAF’s CRAPP requirement when the CF-18s were to be deployed at our NORAD Forward Operating Locations (FOL) thereby delaying the deliveries and eventual operational readiness. Time was of the essence as the VVS Bears were getting more aggressive in their behavior.
Our farthest north FOL is in Inuvik which is located at 68.30740°N and 133.47022°W.

Yes, it can get a** freezing cold up there. Therefore CRAPP is a mandatory CAF aircraft requirement to ensure the pilots can always pucker up in a high G environment.
And what is CRAPP you might ask? Cold weatheR Anal Pucker Protection
Remember kiddies, fighter pilots need to pucker up when pulling high G’s so if you cannot pucker, you cannot take the G’s. You will probably black out and most likely die.
Signs similar to this are found in almost all pilot ready rooms:
- A pucker-a-day lets fight lets you fight another day!
- A good pucker means you can kill that sucker!
- If you cannot pucker, then work as a trucker!
- Have you done your daily pucker exercise? 3 repetitions of 10 puckers. Rest for 5 minutes. Repeat.
The CF-5A was already CRAPP compliant but it did not have adequate air-to-air capabilities. The Bristol folks learned of the CF-18 delay and the possible F-20 cancellation so they did the math: F-18+F-20=F-5.
They looked at the potential of using the F-20 wings, radar and other upgraded components to build a better CF-5 without having to build a new airframe. They did some serious engineering studies fueled by poutine and pizza and built a prototype in 6 months. It worked great like many other Canadian winter inventions like the Zamboni, Skidoo, Snow Blower, Hawaiian Pizza etc.
It past all the CRAPP testing so Bristol got a contract to modify 15 airframes and the CF-5C was born. C represents Cold. Upgraded aircraft aerial numbers were changed from 1167xx to 1169xx.
The program was called: CANOE. Canadian Arctic and Northern Operations Enhancements
Pilots were known as PADLERS: Pilots Arctic Defending Lemmings, Ermines, Reindeer and Seals
The other major upgrade included the engines:
- Original: J85-CAN-15 Orenda manufactured J85-GE-15 for the Canadair CF-116. 2,925 lbf (13.0 kN) military thrust; 4,300 lbf (19 kN) afterburning thrust.
- Upgraded: J85-GE-21 – 3,500 lbf (16 kN) military thrust; 5,000 lbf (22 kN) afterburning thrust.
A part of 419 SQN ”Moose” was assigned to operate the CF-5C.
So pucker up boys and girls! The Moosemen are going out to chase some Bears!

Bill of Materials:
The base kit is the wonderful 1/72 ESCI CF-5A married with leftover Hasegawa F-20 wings, drop tanks and nose.
Paint is Voodoo Grey FS16515. Thanks again to the Fairy Paint Person. To quote the Fairy Paint Person: "Voodoo Grey is sort of like Air Defense Grey's hotter sister."
Decals are from Leading Edge CF-101B and CF-5D sheets.
Painted with a hairy stick.
And how good was the F-20 wing?
The wing profile remained the same as the F-5E, but had modified leading edge extensions (LEX), which improved the maximum lift coefficient of the wing by about 12% with an increase in wing area of only 1.6%.
The original aircraft was fairly sluggish in pitch, so the horizontal stabilizer was increased in size by 30% and a new dual-channel fly-by-wire control system was added. Destabilizing the aircraft in pitch and modifying the LEX improved the instantaneous turn rate by 7% to 20°/sec.
Sustained turn rate at Mach 0.8 and 15,000 ft (4,572 m) rose to 11.5°/sec, which compared well with the F-16’s 12.8°/sec. Supersonic turn rates were 47% higher than those of the F-5E
And now on to the beauty shots.

Carl for the next Nobel Prize in Literature, deservingly so!
So they win a second Nobel prize after the one for gastronomy with their pineapple on pizza...

So you found the Easter egg. Good work Greg.

That's a real stunner and one of your best yet, Mr Gimper!
Pure eye-candy all the way and yet more proof (as if any were needed) that few things spice up a model like those wonderful maple leafs!
Just gorgeous!

Bet you could see these upgrades to the Royal Norwegian Air Force, given how far north they operate. I could see them with a centerline drop tank and Penguins under the wings.
One thing they might find required is the blow-in doors fitted to the F-5E to get full airflow on takeoff for the J85-21 engines (yes, they will fit earlier airframes, Northrop tested them on the F-5B that served as a testbed for the J85-GE-21 engine).

This is definitely not CRAPP. It looks awesome, beefy and with a purpose.
-
Very, very cool looking aircraft, absolute stunner !

What a beauty. Very nice.
