'The Best of the Breed
by Col. "Kit" Carson
Airpower, July 1976
Vol. 6 No. 4
Fw 190A
General Characteristics:
A superb airplane, every inch a fighter. It could do a half roll at cruising speed in one second. Taking this in conjunction with the airplane's high top speed and rate of climb one expected its pilots to exploit its high speed qualities to the fullest without staying in there to "mix it up" in a low speed, flaps down full throttle, gut-wrenching dog fight.
They did. The 190 pilots had a good airplane and some good advice. Nearly all of my encounters with the 190 were at high speeds. On at least two occasions when I met them, my Mustang started porposing, which means I was into compressibility, probably around 550 mph. I don't know what my air speed indicator was reading, I wasn't watching it.
On another occasion, I jumped one directly over the city of Paris and fired all my ammo, but he was only smoking heavily after a long chase over the town. Assuming I was getting 10 percent hits, that airplane must have had 200 holes in it. It was a rugged machine.

Engine and Propeller:
The BMW 801D was a 14 cylinder, twin-row radial with direct fuel injection. A 10.9 foot diameter, 3-bladed VDM prop was used and was provided with hand lever or automatic pitch control. The 801D radial air-cooled engine first appeared on the Dornier Do 217 and the Fw 190. Its most novel feature was the oil cooler system which was a number of finned tubes shaped into a ring of tubes a little larger in diameter than the cooling fan. This ring was fitted into the rounded front portion of the cowling just aft of the fan.
I don't think this was a good idea. For example, my principal aiming point was always the forward portion of an enemy ship; the engine, cockpit, wing root section. If you get any hits at all, even only a few, you're bound to put one or two slugs into the engine compartment. Having a couple of bullets riccochet off the engine block and tear up some ignition harness is not too bad at all, at least not fatal. But to have all those thin-walled oil cooling tubes ahead of the engine is bad news. Any hits or riccochets in the engine section are bound to puncture the oil tubes. Then the whole engine is immersed in oil spray, and sometimes it would flash over into a fire. All of the 12 Focke-Wulfs that I shot down sent off a trail of dense, boiling oil smoke heavy enough to fog up my gun camera lens and windshield if I were so close.
Wings and Controls:
Again, as in the case of the Me 109, no trim tabs adjustable in flight from the cockpit were provided for the aileron and rudder. European designers seem to have acquired the notion that this was a nuisance or unnecessary. Not at all; when going into a dive, it's very easy for the pilot to reach down with his left hand and flick in a couple of half turns of rudder trim. It's not only desireable, but necessary to eliminate side slip for good gunnery. The Fw 190, however, did have electric trim tabs for the elevators.
Performance Evaluation:
The Fw 190's handling qualities were generally excellent. The most impressive feature was the aileron control at high speeds. Stick force per "g" was about 9 pounds upto 300 mph rising to 12 pounds at 400 mph as compared to over 20 pounds for the Me-109.
High speed stalls under "g" load were a little vicious and could be a fatal handicap in combat. If the airplane was pulled in tight and stalled at high speed at 2 "gs" or more with the power on, turning right or left, the left wing would drop violently without warning and the airplane would flick onto its back from a left turn. I scored against a 190 under such circumstances. The message was clear, don't stall it. Our own Bell P-39 Aircobra would do the same thing.
Fighting Qualities:
Excellent high speed, with exceptional maneuverability at those speeds. Range and endurance were markedly improved over the 109. The Focke-Wulf would go 3 hours plus. Visibility with the full view canopy was superb, as it was in the Mustang.
Summary:
Bad points:
(1) Oil cooling tubes at the front of the engines was a poor choice of location. A puncture due to combat damage, or to simple failure covered the engine section with an oil spray.
(2) Lack of aileron and rudder trim controls in the cockpit.
(3) Vicious high speed snap rolls if stalled under significant "g" load.
(4) Poor turning radius due to high wing loading.
Good points:
Everything else was good. In the hands of a competent pilot the 190 was a formidable opponent. The landing approach speed was high and this shakes some pilots up a bit, but I don't think it's anything it's anything to complain about.'
heres the website i found it on:
http://www.geocities.com/CapeCanaveral/2072/Interesting mention of the damage to oil lines on 190.Perhaps it is right how AH has the oil hit so regularly.I certainly wont think its so wrong after reading this will you?
theres also stuff on the 109 but it was too long to post it up in here
