Back in the early days you could get a massive 20 liter engine in a car which put out a astounding 27 horse power   

There is a rule in the engine world..There's no replacement for displacement

Or 'There ain't no substitute for cubic inches'.............

You want cubes my good fellow 
Back of the latest Australian Street Machine magazine there's a page full of engines and there's one which fits this quite nicely.
Chev 632ci huge block V8..it's a 815HP/775lb-ft torque engine you can buy off the shelf 😉
You know how things have changed when a 563HP 454ci is considered a small block  .

Trying to think of something to stick a Centaurus on the front of ?

Chris, assuming it's from a Tempest rather than a Sea Fury, it might fit on a Fairey Firefly?  I've got a Frog Firefly I but I've mislaid the Matchbox Tempest II cowling I have so can't check. Another possibility is a Barracuda.

Cheers Mossie I'll have a look 

I found the Matchbox Centaurus and I think it's doable, with some hefty PSR.  The Frog Firefly I is a bit deeper in the nose than Matchbox Tempest.

The Airfix Firefly V might work better, especially if it's the KP Tempest engine you have, you could make a Z cut in the fuselage to meet the engine better.

I've a couple of SH Fireflies in the stash and a couple more SH Barracudas, so might have a look at those once the current crop is out of the way.

The Barracuda, an aeroplane DESIGNED to be Whiffed!

I always assumed that the Barracuda was the result of an unfortunate mistake in the design office that heroic efforts on the factory floor made flyable.

A Matchbox Tempest Sabre fits a FROG Firefly
You cannot view this attachment.

And a PM Sea Fury Centaurus can be fitted to a FROG Barracuda - I've got one quietly on the go.

[Mossie]

The Sabre certainly suits the Firefly. 

[Wardukw]

Sometimes ya kinda wonder why it wasn't done in the RW .
Alot of what we build looks so much better than the RW examples.

Thats because, unfettered by trivial things like science and engineering we just concentrate on making them look how we think they should.

So, question.
If for this GB I install a 1/20 scale engine into a 1/35 scale vehicle then by how much do I multiply the original cubic capacity to calculate it's new, scaloramaed capacity?
Please show your working.

[Old Wombat]

Divide the original capacity by 20 then multiply by 35 or, more simply, multiply the original capacity by 1.75

It's probably not exact but should be close enough.

[Old Wombat]

Alternately, you could divide the original capacity by 20³ & multiply the result by 35³, which equates to multiplying the original capacity by 5.36 (rounded to 2 decimal places).


In the original version above a 351ci V8 in 1/20 would become a 614.25ci V8 in 1/35

Whereas in the version immediately above that same 351ci V8 would become a 1,881.36ci V8 in 1/35


The difference is that the first equation reduces the capacity & then expands it in only one dimension, while the second equation reduces the capacity then expands it in three dimensions (& is, probably, far more accurate).

[zenrat]

Yes.  It's the second version.  I have to cube stuff as its volume.

Thanks mate.

One unexpected "Re-engine it"  is the real world landing craft  that made landfall on the Egyptian coast in 1941.  Full story here:-   https://www.royalmarineshistory.com/post/2017/12/27/sea-borne-escape-from-crete-in-a-damaged-landing-craft-royalmarines-commando

Blankets sewn together with bootlaces seems to meet the criteria for "re-engining it "
