Twin turboprop (or turbofaned) Avro Shackleton AEW.3

I built a twin turboprop Revell Avro Shackleton MR.3 with a flat nose and the rotodome from a Grumman E-2 Hawkeye a few years ago which unfortunately got whiffed with parts from the Consolidated Privateer.
So after trawling through the 'spares and repair ' models on eBay I found a  project that was started but not finished,  it's another  Frog/ Revell Avro Shackleton MR.3 with a nose weight and broken main landing gear.  There's a bag of spares with the model and an attempt to paint the beast.
I have removed the out engines,  well they fell off! And flattened the nose,  the two resin  turbo-Dak engines fit the inner cowlings but will need a bit of filler and exhaust pipes.
The wingtip fuel tanks are glued on and the cockpit just needs tidying up.  I'll have a look in my various parts bins for the lumps and bumps.
I can remember seeing a photo of a Shackleton with the words
'Royal Navy ' instead of 'Royal Air Force ' on the fuselage,  I'll see if I can dig it out of my pile of reference magazines.

It'd better be operating at VERY light weights, since it's only got two 1200hp engines instead of four 1960hp ones.... :o

Replacing four Griffons with two PT6A-67s saves about 6800lb in weight, thus bringing the enpty weight down to about 44,600lb. For comparison, a Turbo-Dakota (Basler BT-67) has an empty weight of 15,700lb.

They could just put every other rivet in, that'd save at LEAST 20 tons!  ;) ;D
Kit's Rule 1 ) Any aircraft can be improved by fitting longer wings, and/or a longer fuselage
Kit's Rule 2) The backstory can always be changed to suit the model

...and I'm not a closeted 'Take That' fan, I'm a REAL fan! :)

Well with less weight to carry, they could fit it with shorter wings, say from a DC-3, then because of the lower weight they could give it the lighter undercarriage from something like a C-47, and since it wouldn't be able to to carry much volume they could give it the shorter and less draggy fuselage from a Dakota, and... hey, wait a minute....  :unsure: ;)

- Can't be bothered to do the proper research and get it right.

Another ill conceived, lazily thought out, crudely executed and badly painted piece of half arsed what-if modelling muppetry from zenrat industries.

Two Armstrong Siddeley Python turboprops would be about right: 4110hp and 3450lb each.

Two Pythons: 8220hp, 6900lb

Four Griffons: approx. 7840hp, 7920lb.

These are plenty of cheap Wyverns around to butcher, and you could always stick a pair of Nenes from a Lancastrian testbed conversion on the outer nacelle positions to give a real hot-rod...

There's some concept artwork of a Shackleton with the engines from the Boeing B-29 in the book 'Nimrod a Genius ', although I might have to change the propellers.

I have a plan using Pythons on a Shackleton (IIRC I had written about it here too sometime ago). As the air intakes for the engine are right at the backend of it, I was thinking of doing something similar to how the Herald has it's turbo-prop engine intakes. Sorts out the undercarriage at the same time.

I used a pair of turbofans on a tailless Avro Shackleton  build  project,  these came from a Matchbox A-10 kit.  I will be adopting this method on this build  meaning I can finish both together.  :banghead:

I've a FROG MR3 built a bazillion years ago that I want to rebuild as a whif.  Love the twin Python idea, never struck me before.
