Now *that* is interesting.  I really wonder what engines are fitted and exactly what the top of the nacelles looks like (that appears to be where the exhausts are).

Now that website really shows how the exhaust is routed --  I have to do one like that --   ;)

The RAAF (probably more like some private contractors) were looking at turbo prop conversions for their Caribous, on and off, for a couple of decades.

An RAAF turbine Bou would be cool...how cheap are those AModel 1/144 kits?

About £17 retail in the UK, although you can find them cheaper at shows. I've got the ACLS Buffalo and I doubt whether I paid that much for it (although I can't actually remember).

Modelsua (Ivan) sells them for about $14-18 USD.

I can vouch for Iavn. Good seller.  He will flatten your kits to reduce shipping costs.

Combat Models do a 1/72 Buffalo, plus there's the Hobbycraft 1/72 Caribous,

Thanks 617, but 1/144 is enough for me! Although I bet the Hobbycraft kit can be had for about the same price as the AModel ones!

Thanks for the heads-up on Ivan, Mr Gimper.

A casual search finds both Oz-Mods and A-Model 1/144 kits available on eBay.

A little off topic gent's, but I must say I miss the Wombat/Bou immensely  :(
I think it a grave loss that the Caribou never adopted the turboprop as a natural progression!
Although I spent quite some time in and out of Bou's, can anyone tell me if the DHC-5 Buffalo, being bigger and heavier than the Caribou, did it have the similar take off and landing (STOL) performance of the Caribou?

From the Internet (your mileage may vary). Variable include weight, distance to clear a 50' obstacle etc. These are my interpretations.

DHC-4:
Takeoff: 725 feet (221m) at 28,500 pounds. Clear 50 ft (15 m) obstacle 1185 feet (361m)
Landing: 525 feet (160m) at 26,000 pounds. Clear 50 ft (15 m) obstacle 1235 feet (376m)

DHC-5:
Takeoff: 1,040 feet (317m) at 41,000 pounds (18,598kg) on grass. No data if this includes clearing the 50' obstacle.
Landing: 610 feet (186m) at normal landing weight on grass. No data if this includes clearing the 50' obstacle.

Thank's a lot The Big Gimper!
Unfortunately the Buffalo doesn't look like it had the gut-turning take off performance (alas the stats you give have the Buffalo at almost double the weight!)
I've just always viewed the Buffalo as a natural successor to the Wombat/Bou! I don't really see the selection of the C-27J as a real successful successor to the Wombat/Bou and its amazing STOL capability! I'm hoping I will possibly find out in the foreseeable future ;)

You are picking out just a single feature of the platforms.  The C27J was selected to a different specification and for a different role than the DHC-4.  Moreover, it was selected to operate with an ADF some 50+ yrs removed from that in which the DHC-4 was to serve (the first RAAF DHC-4 being handed over Feb 1964 - the first C-27J arriving Jun 2015).

For the sake of not the topic/forum, I do not want to get into a slogging match GTX. So I'll keep my opinion and experiences to myself  ;)

Often when looking at a Caribou head on it looks like it is in the process of folding up its wings:

So why not accentuate this with real folding wings and make it a Naval COD bird - one wouldn't need arrestors... ;)

And with enough wind and the cruiser going all-out, it might just land and take-off again from the cruiser's heli-pad.  ;D

Letz see,,,, 1/4 fuel, no cargo or empty seats or nuttin in cargo bay, fresh tune-up on engines, lightest weight pilots in the service, cruiser just had hull cleaned for max possible speed.
Go ahead do it.  Take lotz of video.  Success or failure I will watch it several times.

Well, you know that we used to joke in the RAAF about the Caribou being the only aircraft to suffer birdstrike...from the rear! ;D

I thought that was, and is, said about the A-10, too.
