Yes, that is also what I discovered, Spit 1 can actually stand half a chance at high altitudes on ATAG. The spit 1 is no joke, can get to 20,000 feet in 10 minutes standing it on it's tail.

I also get your same figures at low altitude, but I couldn't get 290mph in the Spitfire 1a octane.

Game is whacked.

Conclusion: If you are on Repka or flying low on ATAG pick Spit 2a. If you are doing high altitude flying and climbing, pick Spit 1.

For testing I set up a mission in full mission builder, for 1000ft it was set up to spawn at 1500ft and 490kmh as soon as it spawned engage autopilot, wait till it settles down and gets up to max speed then disengage autopilot, still flying level adjust radiator and revs then shallow dive to 1000ft hold it level for 20 seconds while any speed from diving has bled away then press pause and take a reading of the speed.

The 100 Octane improves performance up to c. 10,000 feet, after which the boost drops off rapidly. The constant-speed props (de H and Rotol) provided the best overall improvements in T/O and landing distances, climb rate and ceiling.

Huh? Have you been on the tinnies old bean? The DH wasn't a constant speed unit......:confused:

NZ was referring to Real Life, not CoD's interpretation, old chap!

Ah, thanks mate. Easy to get confused, what?! As with MkI, MKIa, etc. ;)

There is one thing you are missing. You need much longer than 20 seconds for an accurate measurement. Put the game on 2x or 4x speed (trimmed properly of course), hold the altitude and then you can get a very accurate reading. 20 seconds is not long enough, it will hold speed from a slight dive for longer than you think, throwing measurements off.

Anyway... our figures are the same.

Oh another thing worth noting is that all the aircraft (including 109 a little but by far most notably RAF planes) perform way better with CEM off, completely differently actually. Much closer to real life performance.

Perhaps with the game in it's current porked state ATAG can try turn off CEM to give the reds a bit of a chance? Just a thought.

Snapper mate, do you have anything to add at this point? :lol:

Trademe, we've been working on this stuff for a few weeks now, and I agree completely. ;)

Edit: but not necessarily with ATAG turning temps off. :D

It gets a little confusing! A2A's Wings of Power Spitfire 1a has the 2-speed prop (with a hand control that looks like a bicycle pump! LOL) and the undercarriage is hand pumped up & down. To top it off, A2A asserts that the RAF pilots figured out how to create a variable speed effect by carefully manipulating this bicycle pump control in the middle of its travel, which A2A have modelled in. It's not Constant Speed, though, so it has to be carefully monitored since the engine rpms will wander up or down with maneuvering.

A2A's 2a is very similar to CoD's 2a, except it uses (correctly) a cartridge starter.

A2A "pro's"

Much more detailed cockpit - every switch, lever works
Engine performance considerably more powerful (similar to CoD's über Sissyfire 2a ver 1.05)
Engines harder to overheat (but they will)
Merlin engines sound like.....Merlin engines! (Not CoD's "Diesel Merlins")
Very detailed systems are modelled, including Oxygen
Maintenance on engine highly detailed

A2A "cons"

Gun button doesn't work!
Damage modelling largely confined to engine wear & abuse
Pilot figure uglier than CoD's pilot figure -- how can THAT be possible?

Trademe, have a look at this thread, from post #149 on. ;)
