SPIT MK I/II and over boost

You don't need to be a rocket scientist to see that the Spitfire outperforms the 109 on the graphs. Now take a look at the same aircraft in IL2 compare UP2.01 (maybe there's a later version, I gave it up). You'll see the 109's outperform the IX Spitfires.

You don't need to be a rocket scientist to know why on the most biased spit dweeb's home-made graphs the performance tests are cheery picked in such way that that it would show the most poorer performing 109s tested against the best performing Spits tested, and omitting the poorer performing Spits and better performing 109s. Come on, the credibility of that site's fan articles have been discussed in lenght already.

The 109G-2 was imho one of the most accurately modelled aircraft in the old Il-2. And it did historically outperform the early Mark IXFs with the Merlin 61, up to about 8000 meter.

That does not surprise me at all, your opinion that is.

[QUOTE=41Sqn_Stormcrow;375412]I think we need to apply some common sense here. 100 octane was apparently used but there are serious doubts that it was used in each squadron and each Spit. It seems there is no data available that proofe that all Spits flew with 100 octane fuel.

Agreed.

- should we implement the 100 octane spit types as default even if it is quite probable that not all had this feature?

I think the answer is definietely yes. Server hosts and mission builders can decide their take on the level of availability of the fuel.

- Should we procede then also in the same manner with all the other planes in the game that is to go for the high performance variant of it even if we do not know in which number they've seen action?

- If we had the numbers which should be the threshold to decide that the default plane should be the better performing one?

(I presume that nobody here would really support the application of a certain logic in a one-sided manner that is only go for the highest performance variant for one particular side)

These questions are not rhetoric. I think we should ask ourselves this because I think it would be a fundamental decision that would be taken by the devs.

I think the answer to these question is also a definiete yes, otherwise it would be quite clear that some fanboys are just craving for the "bestest" versions of each plane for their side, while trying to deny the other side from the same.

I for one would consider for example Bf 110C / 601N, ie. C3 types a neccessary addition (since about half the Zestorer units were flying these during the battle, its a plane that was important but not represented yet), and as for a C3 109 probably the Bf 109E-7/N would be a good choice. Its the first mass produced 601N variant, would be absolutely useful for later (Afrika, Med, Balkans, Barbarossa) maps, and it could represent well the earliest examples, since performance was the same.

Well people will just have to measure it's weight against your opinion's weight, m8. :p

If the a/c is based in 11 Group, it used 100 octane fuel.

There were over 50 such airfields. The complete list can be found in one of the earlier threads.

You simply picked the ones that have evidence of 100 octane fuel supply, and pretended they are the only airfields used. In short, you lied.

[Kurfürst]

Based on the current evidence (feel free to add new sources showing 100 octane at the said airfield during the Battle and I'll update the list) shows that 100 octane aviation spirit was supplied to

8 out of 19 Sector Airfields
9 out of 32 Fighter Airfields (however 7 of the 32 functioning as satellite airfield for rotation etc., with no Sqn permanently based there).

The below is a detailed list of Fighter Command Stations during the Battle of Britain.

I've marked the ones you listed above which show some kind of evidence of 100 octane fuel being supplied to them (usually Combat reports in the literature) with an underline. Coloring would be better but I am not sure how to this with this forum engine.

The following list of stations and associated Squadrons also give a fair idea about the extent of Squadron movements during the Battle, and how it complicates things..

The source is below.

Even as comprehensive as that list is, its still not the full picture, as often a squadron that was based at a sector airfield would often have a flight operating during the day from a satellite.

For example, whilst 54 squadron was based at Hornchurch, at first light a flight would often fly down to Manston, and operate there for the day, flying back at dusk.

Still its an impressive guide as to roughly who was where roughly when.

An observation, it would be even more complete if it added the there rotation out dates as well, and if the dates were more accurate.

For example, with 54 squadron, there date's based at Hornchurch would be,

Spring - may 30th
4th june - 24th june
25th June - 31st July (Rochford & Manston, Satellites of Hornchurch)
8th aug - 3rd sept.


Which by the way don't tally with your dates, mine are from there own ops book, where are yours from?

You missed Debden which had 100 octane since Sept 1939.
