12 lbs boost

I figure top speed is top speed ie. balls out full throttle-through-the-gate-gonna-catch-that-yellow-nosed-bastage top speed....even if it's only gonna last 5 minutes on a good day. :grin:

Others more learned than I (and there's lots of THEM!) may differ, and so be it. Me? I just wanna shoot 109's. Oh, and 110's, too. :-P

He means that if we would have +12 boost in-game, which would add 25mph to the +6.25 in-game speed, the in-game speed at +12 boost would be within 5mph of the real life +6.25 boost.

Thanks, Banks! That's what I meant to say! :)

In terms of performance I find also the Bf-110 C-7 a bit too slow. I can't exceed 420-430 Km/h @ s.l., no payload, with 50% fuel, rads full open. From the Internet I find for the C-4 (same DB 601N 1200 hp engines, theconly difference being the bomb racks):

Bf 110C-4 - Maximum Speed: 294mph (473km/h) at sea level, 349mph (561km/h) at 7,000 metres (22,965 feet)
Cruise Speed: 217-262mph (349-422km/h)
Time to 5,500 metres (18,045 feet): 8 minutes
Service Ceiling: 9,754 metres (32,000 feet)
Range: 565 miles (909 kilometres)

LOL! With dangerous maniacs like you in circulation I would reduce the Spit's speed even a little more then! :-D

That's not good. I have no hard data in front of me, but my impressions of the 110 are that if it jettisons its load it was tough for RAF fighter to catch. And if they did it it was no pushover -- it had huge firepower (including a rear gunner) and speed, but not as maneuverable as a single seat fighter.

Sounds like the 110, as modelled in this sim, should be 40 - 50 kmh faster at sea level.

Dont think such suorce is reliable for Bf 110 C-4 both for ground level speed and FTH speed.

Thank you Kwiatek.

BTW, I've tested on ATAG the story that the Emil now turns inside Spits: it's not true, from my humble point of view.

I got behind a Spit IIa while on my E-4, and when he turned I tried to follow it on purpose. Well, despite I'm not a novice 109 pilot, Pomidor303 was in an advantage position scoring hits in less than 2 turns, and then only some scissors and the low light of the dawn saved me.

Ah BTW the sound radar is still there, when reds canopies are open :-)


Cheers!

Your first graph refers to the DB 601A, with some 100 hp less IIRC. Speed at s.l. matches the C-7 in-game, but the latter has a DB601N rated at 1200 hp. The second graph is just an estimate based on the "drag and power". It gives only 3-4 km/h more to the C-7 against the C-1/2 for 9% more power ... just 1% more speed ... not a great interpolation imho ... :)

Unfortunately still besides Spitfire MK II ( 87 octan version) most fighters are off in speed performance. British fighters are even lack in speed for 87 octan version - the most hurted now is Hurricane. Im not sure - didnt check before beta patch but it seemed for me that Hurricane was more accurate then now. Just 109 E was too slow.

So i think 1C has still a lot work to do here.

The same like with some flying characterstisic of some planes.

Example im sure that 109 E slats open at too low speed at too low angle of attack. In straight fly with idle power slats open below 150 km/h when it should open according to British test at 111 mph/180 km/h ASI.
