I believe the worst avoidable accident still is the Tenerife one.

Apparently, they had longer cowlings, though how that worked I don't know.
Radiator housing/bottom cowling actually, so it might not be quite as noticable.

On the other hand, if you notice that your aircraft often return riddled with .303 sized holes, but rarely return riddled with cannon holes, it is reasonable to entertain and research the idea that the ones that meet cannon fire are less likely to survive the encounter.
The point being nobody asks those questions about a bomber that was equally riddled with holes but did not make it back.
The suggestion seems to be that .303s can't possibly down a He.111, and losses including crashes on UK soil rather preclude that.

Hi Michael, apologies, Martin is currently trading as Air-Craft Models, predominantly on ebay https://www.ebay.co.uk/sch/i.html?ssPageName=&_ssn=aircraftmodels&LH_Complete=1
Looks like he's limited ordering to UK only, the listings are only visible on .co.uk and not on any other tld that Ebay has.

I would be a bit wary of personal anecdotes. They are best backed up by solid data and documentation.
They did the sums, and decided on cannon armament for good reasons.
And it's not exactly a new discussion either.
https://www.quora.com/When-mounted-on-fighters-during-World-War-2-how-did-the-50-caliber-machine-gun-compare-to-the-303I do want to show you the difference in rounds used.
A 20mm HE shell is not only going to punch a hole, it'll also blow things apart.
The Germans introduced a 20mm Minengeschoss (explosive shell) mid-1940 on the MG-FF/M, and that had a relatively low muzzle velocity and lower rate of fire than the Allied armament.
Hispano Mk.II 20mm: 600–850 rounds/min, 840–880 m/s muzzle velocity.
M2 .50 caliber: 550–1,300 rounds/min, ~900m/s muzzle velocity.
So, .50 and 20mm are comparable in RoF and velocity, but packing a much bigger punch. Swap 2-3 M2 .50s for 1 20mm cannon and you're doing more damage.

Not surprising, it's one of those click-baiting Hoo-raaah stan accounts.

Chris does his research and does not take first-person anecdotal information for granted.
Gut feelings are nice, but evidence in test reports and analysis of results are better.

There are indeed many photos showing Luftwaffe bombers riddled with .303 bullet holes but which managed to return safely, so if we'd had cannon or the .5 inch Browning the results may well have been different.
Again.
The ones that do not make it 'home' you will not read or hear about.
Survivorship bias.11 minutes ago, PatG said:Interestingly in Korea the US still used .5 inch Brownings in the Sabre compared with the 20mm and 30mm guns employed by the Mig15s so which option was better I wonder?
As said, the 20mm cannon development in the US took quite a circuitous route, from the M2/ M3 to a Colt Mk.12 and eventually a M39 (based on the Mauser MGs) intended for the Sabre that was just a little too late to see action.
MiG-15s used 23mm NRs & a single 37mm (makes sense as a bomber interceptor), with the 30mm variant only introduced on the MiG-19 so outside Korean War scope.
11 minutes ago, PatG said:Just wonder why we didn't think to use the .5 inch Browning in BoB Spitfires and Hurricanes, say 1 per wing plus two .303's given the problems we had at the time developing the Hispano cannon which proved to be very troublesome with numerous jams/blockages?
The .50 was not in use in the UK (well, barely).
So then logistics comes into play. If you decide to take a stop-gap measure by introducing that .50 you also have to adapt not only the aircraft itself (as the .303 browning is smaller and lighter) but also you have to arrange for a separate ammunition flow.
And since the intent was always to use the Hispano 20mm, the eventual use of the .50 in the E-wing Spits is mostly because by that time there was plenty of supply around (and it nicely got rid of extra weight in the outer wings).-

Interestingly the US, with some minor exceptions, never used the 20mm cannon and preferred the 0.5 inch Browning instead
Mostly because they could not get their M1 variant of the Hispano Suiza 404 (itself a further development to replace the Oerlikon-based variants) to work properly, delaying the introduction. Similar issues with early versions of the HS.404 in UK service were the reason why the Mk.Ib trial with 19 Sqn was such a bad experience.
The US armed forces then reworked the British Mk.II Hispano into the AN-M2* but that also proved problematic, one of the reasons the P-38 had a recocking mechanism in the cockpit for dealing with misfires.It should also be noted that autocannon were pretty rife in the late 1930s, especially with the French. They had those long-barreled 20mms as defensive armament on the LeO 451 and the intended armament of the SNCASE 1000 ground attack aircraft was 4x HS.404s.
Then there's the Danish 20 and 23mm Madsens, used by both the Danish AF and Dutch LVA.
47 minutes ago, Mark Harmsworth said:I may well not know what I am talking about (surprising, I know) - but weren't there examples of Luftwaffe planes returning to northern France during the BoB decorated with dozens of little bullet holes but no real damage? Or is that just a myth?
Well, the ones that don't return tend not to get much notice, do they
anyways:
https://web.archive.org/web/20171030102939/http://quarryhs.co.uk/WW2guneffect.htmThe original idea the USN had was getting sufficient boom on target, and three 50cal M2 Brownings could be replaced for less weight overall by one cannon for equal firepower.
*AN prefix here means Army/Navy, so both services would use the same weapons systems.

Has anybody from the UK or other countries had any experience of purchasing from modelwereld.eu from the Netherlands.
I've read some good things but, also some bad things about their service.
Curt is generally a good egg.
It is however a 2nd hand trader (mostly), so expect some prices to be a bit elevated. Postage inside EU (DHL mostly) is reasonable, don't know how well that translates to ordering from the UK.
I've not had problems ordering kits there, but then I have a home advantage (close enough that he has delivered orders in person).-

Do you suggest that these should go completely unanswered? With any misunderstandings, should there be any, left to spread unhindered through the web?
The suggestion though is not to have the question not raised at all, rather to have it not clutter a thread on a completely different subject matter.
I quite fancy a good discussion on cannon armament personally, so if Pat feels so inclined, have at it in a new thread.-

Just anecdotal, but nonetheless, flying the Spit or Mustang in DCS requires regular retrimming when under different engine loads.
And even max trim on the rudder is not enough to prevent the nose from swinging out on take-off, so that is certainly the moment to use the pedals. -

Microsoft pulled out the Mpeg-2 DVD bits from Media Player a couple of years ago due to licensing costs, I believe.
They now supply that as a separate download in the Store.

With MRP this was not the case, I did not thin it at all and that worked pretty good. On the other hand I found it more difficult to clean my gear afterwards, the paint is more sticky. Furthermore I really felt the need to open a window during my spraying sessions, which was not the case with the other brands.
It's more like an acrylic laquer, and smells like house paint
MRP is pretty easy to clean out with Mr.Hobby Leveling Thinner, so if you intend to use it more often getting one of those smaller 100ml glass bottles may be worth it.That grey green camo definitely would have made the Dutch F-16s look special. Any plans to build one of the Belgian ones in the proposed two greens & tan?

I've been looking at the Hasegawa kit as I want to do a Klimov-engined conversion, but I'm going to hold off now!
Just wait for the Hase ones to hit the 2nd hand market once this one is out (or pick up the inevitable overtree box).

It is a bit dark, but not like that pic shows.
I do note that they say they brushpainted it, which in my experience tends to work less well.
Spraying leaves a thinner coat so less 'dense'.

You can make it as cheap or as expensive as you want.
FineMolds do weps sets in 1/72 for their 60/70s Phantoms.
The Hase sets tend to pop up every now and then at HLJ and the like.Here's a decent collection:

At 7:06 you can see extended speed brakes.
But not clearly visible at touchdown.
But why they should retract them ?Good spot. OTOH, 7.36 is a turn onto final without.
Guess they're not that effective once the flaps are down anyway.
