Twitch said:Iwe must remember than all prototypes fly faster in tests since they don't have any armament installed! and like most Italian fighters the 2005 was heavily armed with plenty of ammo-
2- 12.7mm Breda-SAFAT w/ 350 rounds per gun
1- engine mounted Mg 151 20 mm with 150 rounds
2- wing mounted Mg 151 20 mm with 150 RPG
Absolutely not. The max official speed of the C-205 was of 648 Km/h. 30 Km/h (5%) of difference in max speed, even if the aircrafts look similar, is nothing so strange.Twitch said:Dogwalker- S does that mean we should automatically boost these planes speed to over 420MPH?
Twitch said:That sounds the same just about every aircraft project after WW2 in the US
Maximum speeds and time of climb:
sea level - 497 km/h
1000 m - 521 km/h, 39 s
2000 m - 544 km/h, 1 min 28 s
3000 m - 566 km/h, 2 min 28 s
4000 m - 586 km/h, 3 min 32 s
5000 m - 595 km/h, 4 min 40 s
6000 m - 587 km/h, 5 min 55 s
7000 m - 584 km/h

From what I know, the usual figure of:
6,560 ft / 2,000 m: 421 mph / 678 kph
13,120 ft / 4,000 m: 351 mph / 565 kph
19,685 ft / 6,000 m: 421 mph / 678 kph (6,950 is a mistake of Aldini,s site)
22,965 ft / 7,000 m: 421 mph / 678 kph
came directly from the Regia Aeronautica acceptance paper. To be accepted from RA for the production series the aircraft, even if it was a prototype, had to be tested with full ammo, and even painted.
All the fonts (even Ing. Gabrielli, itself) said that the Re 2005 was the fastest of the "5 series" fighter, and the official max speed of C-205 whit full ammo was 648 Km/h at 7500 m, so the Re-2005 had to be faster than that.
The official speed was obtained from the first prototype (MM 494), whit a RA 1050 Tifone engine, but I don't know if the limitation at 2650 rpm (that could be easily avoided in a test prototype) was operative.
Some fonts report a max Speed of 686 Km/h at 6,950m (from this the mistake in Aldini's site) for the prototype, but it was obtained (if it was obtained) first than the official tests of the RA, however Longhi ever refers to this speed as the max speed of Re-2005.
The second prototype (MM 495), for german's request, was fitted with an original DB 605, with MW 50, and a VDM propeller, and this reached up to 700 Km/h at 7000 m, but how much is this "up to" and the conditions of the test are unclear, since the germans themselves made the test.
The prestations of the production series fighter (if the word "series" could be used talking of Re 2005), like that of all the aircrafts of the war, probably fell below that of the prototype.
