No chance of a Whirlwind I would suggest.

More bits of Whirlwind I think survive than Hornet too.

Plans for a replica Whirlwind ground runner - http://www.whirlwindfighterproject.org/aboutus.htm although this worries me a little - "The total materials only build cost is projected at £35-£40,000. " but if it's not needing airworthy stressed parts then maybe?

Nothing about a Hornet.

The show stopper for a flying Whirlwind is the engines. You could recreate a Hornet airframe and buy a couple of Merlins as has been done with Mosquitos, but Peregrine engines simply aren't available.

During the war the Peregrine was notoriously unreliable (due to lack of development) and as far as I know there are none in existence.

I am not keen on replica aircraft UNLESS the replica is pretty much identical to the original. The recent Mosquito projects are Mosquitoes in every sense. Even the 262s are pretty much real 262s - with the exception of the engines - which, as I said earlier, HAD to be modern replacements for the deadly Jumos of the original.

They could perhaps have been slightly more authentic if they'd used French Atar engines, developed from the BMW 003 used to power the prototype 262s. Have to resist the temptation to use an afterburning version though.

I suppose they had to go with what was available, affordable, reliable and marketable.

The Jumos had an expected operating life of only 10 hours - and many never made it that far.

so in other words exactly the same scenario as the Whirlwind?

The Whirlwind performed as well as it did (when it worked at all) largely due to the compact size of the engines which is why they weren't replaced with Merlins at the time. A Whirlwind replica with Merlins would not only not behave much like a Whirlwind, it wouldn't even look like one.

I saw a 1/72 model of a Whirlwind that someone had made with engine cowlings from a 1/72 Mosquito to represent Merlins instead of Peregrines, it looked bizarre.

The problem with building replica PISTON engined WW2 aircraft is finding engines that adequately replace what powered the originals.

If you can get original engines and if you follow the original plans and construction methods then you are probably not building a replica but a new original. The two Mosquitoes built in the past few years are effectively brand new originals.

The problem is exacerbated with aircraft that were fitted with in-line liquid cooled engines that no longer exist. There are no modern equivalent engines that can stand in to replace them. That is why it would be difficult to build a Whirlwind.

Radial engines are less of a problem.

A Welkin might be a better proposition as it did have Merlins but the original is not well known and relatively few were made -

With CAD/CAM techniques advancing so fast, is it possible that within a few years it will be practical to make brand new Peregrines, Napier Sabres etc?

Some of the process would be easier but making complicated devices like high performance piston aero engines will always be an expensive activity. At the end of the day, if you have someone with a big enough wallet and a big enough interest in a subject,so who's saying what might get built in the future.

They could have taken the ladder away and held up a few cut out paper planes.

Photoshop I assume since it wasn't taken at Waddington which would have been the most likely / only(?) opportunity to get something like that.

Yes - look at the colour of the sky around the upper Lancaster's tail wink

Not Southend, too many trees, not enough buildings. Good as the image is, is a shop
