I love the rudder on the 109.... going to the left is a fair point... it's not as effective to the right, but it still works like a parachute if you use it right.
The 109s acceleration combined with a rolling, hard rudder input stop is a great way to get a con on your six to slide by and into perfect 30mm range.
My gunnery is hopeless, especially now that I fly so rarely, but the 109 is such a great dogfighter and the rudder is a real part of what makes it so good in a knife fight.
Whereas with the 152 and its rudder... I don't find that its good rudder control is of real benefit to you. If you're relying on it in a fight chances are you've already lost. (At least that's the case when I fly it... I'm a bit rubbish)
