Looks like it is from Winkle Brown's book.

Similar for the MK108 in the Bf109. The heavy belt would not feed.

Fw190 units that did ground attack were the Fw190Fs. No 30mm cannons but retained 2 of their 20mm MG151/20s.

That is correct that the 30mm cannons were built into the wing (/R2 and /R8 ). They were MK108s NOT MK103 which were mounted below the wing in a gondola. The twin MG151/20s gondolas (/R1) were used by even less units than the /R6 equipped units.

We don't have bombers to shoot at.

The caption say 'late war Bf109G'. The MK103 was only trialed on the Fw190. It was a failure.

Why would anyone want to hang gun pods under the wing of a 109? They sure didn't help the performance of the a/c at all. One of the excuses hears when comapring a/c is that the 109 didn't perform as well as it should of because of the gun pods.

How do you expect the canopy to open without busting the canopy glazing? The distance between the canopy tracks was wider when the canopy was in the closed position than when in the open position.

Also called I believe a yo-yo turn. RL P-47 pilots used this while chasing 109s with good results. There is also the lag displacement roll. This is a must read, http://www.combatsim.com/htm/2000/09/stk_eaw_new/page2.htm

Aiming for the nose is better as if you are little off you will have your bullets hitting further back on the enemy a/c.

The trim and flap wheels operate incorrectly. There should be a pause every 1/3 turn of the wheels.

According to my P-51D Handbook limiting max speeds: All speeds are IAS. 40,000 ft. = 260 mph (418kph) 30,000 ft. = 300 mph (482kph) 20,000 ft. = 400 mph (643kph) 10,000 ft. = 480 mph (772kph) 5,000 ft. = 505 mph (812kph)

Why because the German a/c are late '44 a/c. Nothing to with balance but the time period. As OKL, Lw.-Führüngstab, Nr. 937/45 gKdos.(op) 20.03.45 is oft quoted by some as proof for 1.98ata K-4s, this backed up by actual data that 25lb boost was used, unlike 1.98ata with no proof of actual useage, should be enough to have 25lb boost Spitfires.

On unpaved strips RL 109 pilots would let the a/c drift a bit so the take off run was more of an arc.

P-51D-10NA and P-51D-5NT: Added elevator bob weights. These helped offset the rear CG problem with the aft fuselage fuel tank by acting to pull down on the elevator cables in a tight high-G turn. P-51D-10NA: Added dorsal fin and reverse boost tab. P-51D-15NA: Standardized landing gear warning lights. P-51D-10NA: Replaced mechanical oil temp gauge with an electric one. P-51D-5NA, P-51D-5NT: Moved supercharger aneroid switch from firewall to cowling former. P-51D-15NA, P-51K-10NT, and P-51D-25NT: Replaced direct reading fuel pressure gauge with a pressure transmitter. P-51D-10NA and P-51K-5NT: Two speed booster pump switch replaced with single low speed switch. P-51D-20NA, P-51K-15NT, and P-51D-25NT: Electric PRIMER pump replaced the manual one. P-51D-20NA #401, P-51D-25NA, P-51K-10NT, P-51D-20NT: Replaced fabric covered elevator with a metal covered one and changed the angle of the tail incidence.

Actually MachDriver, C3 was available in 1940, tho in low quantities. Some Bf109s and 110s were using it in the later part of the BoB. The Fw190As with the BMW801D engines required C3 fuel and they were around from 1942.

72" was the standard boost. A very big +1 for the rest.

Yes Crumpp your denial is well know. "It was decided that Grade 150 fuel was to be the only fuel available for AAF fighter airplanes in the United Kingdom." If it is the only fuel available, would that not make it the standard fuel?

March 1945 How is that relevant to 1944? 2000hp K-4 is a 1945 a/c and only showed up (debatable) in the last few weeks of the war in Europe.

The first P-51Ds arrived in the ETO in March 1944. Dora - Sept '44 so 6 months after P-51Ds K-4 - Oct '44 so 7 months after P-51Ds

Yes we have an early '44 P-51 vs late '44 Doras and K-4s so definitely no balance. The performance difference will be even greater when the Spit IX arrives. If and when the P-51 gets 150 octane fuel the P-51 should be more competitive. If the Spitfire IX gets 25lb boost it to will be more competitive but still be at a disadvantage. Only with Spit XIV will there be any sort of balance.

This 75 octane must be a typo Yob because the standard fuel for the Merlins was 100/130 octane? In overall numbers the P-51 outnumbered the Lw but on the bomber escort missions not so. It might say 600 P-51s escorted the bombers but those P-51s would be spread out all along the bomber formation and not all of the 600 P-51s were with the bombers at the same time.

maybe the weight balance (CoG) is not set correctly.

The first one sounds like some ill tuned American jalopy.
