Post-war flight tests confirmed or denied the myth?

I suspect that most single-prop planes will turn better one way than the other, but can't see any particular reason why it should be more 'drastic' in a Bf-109 than in any other type. If the general torque, gyroscopic and p-effects are modelled correctly, there should be no reason to treat the 109 as a special case without strong evidence.

I try never to turn right but it all has to do wit torque. Don't all single engine aircraft have propellers? Why is it such a big deal with a 109. I would think a small plane like a Yak 3 would also be effected.

I was thinking along those exact lines! Too bad I watered it down. But you said precisely what I was originally thinking. (sometimes my mind-melding technique has a delayed reaction ***Send me all your money!!!***)

But turning left I find I can out turn a P-40 in an F4 if I'm careful

I wouldn't call it solid data, but the following may be of interest, from here: http://www.pilotfriend.com/flight_re...reports/33.htm

Directional Trim
Absence of rudder trimmer is a bad feature, although at low speeds the practical consequences are not so alarming as the curves might suggest, since the rudder is fairly light on the climb. At high speeds, however, the pilot is seriously inconvenienced, as above 300 mph about 2 1/2 degrees of port (left) rudder are needed for flight with no sideslip and a very heavy foot load is needed to keep this on. In consequence the pilot's left foot becomes tired, and this affects his ability to put on left rudder in order to assist a turn to port (left). Hence at high speeds the Bf.109E turns far more readily to the right than to the left.

Interesting link, Winger.

Note that this refers to high-speed turns, rather than to a general characteristic of the Bf-109. I'd say we need to see how the sim models aircraft behaviour in general before we start asking for any specific 'fixes'. As I suggested earlier, a good physics/flight model should be able to reproduce this based on the known attributes of the aircraft, rather than needing 'tuning' to match test reports. If it doesn't, then maybe adjustment might be necessary.

I notice your link also refers to the heaviness of the 109 elevator at speed, and the consequences of adjusting trim. It looks like Oleg got this about right in IL-2....

[RAF74_Winger]

I'm most interested in the aileron snatching with asymmetric slat deployment - in fact, with IL2, I've never been able to get the slats on the 109 to deploy asymmetrically, don't know whether it's a flight model shortcoming or if the slats are there for show only.

I know that I've never experienced uncommanded roll in the 109, except beyond critical AoA.

I may be wrong, but I was under the impression that IL2 had a numerical flight model rather than one which was calculated (like X-plane). I'd be interested to know how the flight model actually works and if this will change in SoW.
