short 109 pilot interview

So the 109 is good at yawing? First time I heared that, though it makes sense I suppose.

erm..no.

First of all, that's a Buchon, not a 109, and the pilot is talking the usual "I'm flying the best plane in the world" gibberish.

Does that make much of a difference? Yes. If you look at the Buchon from its side, the propeller axis sits higher than on the 109, which means that most of the slipstream travels above the wings and straight into the rudder, while on the "normal" 109, the same slipstream travels a bit lower.

The "yaw happy" behaviour is mainly cos the plane is really short (not long, as he says) and very light, and yes, probably more nimble than a Mustang at low altitude, but the way he delivers his impressions comes out a bit confusing..

Bottomline: whatever this guy is talking about, it has nothing to do with WW2 fighters, cos he's not flying one.

Im no aerodynamics engineer but regarding your comment on the yaw and position of the prop I would have thought that having the engine placed lower would lead to better control as the higher prop would lead to more of the surface being affected by prop wash??

yes, in order to be efficient, a control surface needs to be in a good airflow, with propwash the air gets rammed down along the fuselage and into the control surfaces,making the surface more efficient. The problem is that the movement is turbulent and circular, so if you don't have a long tail surface it might affect lateral stability (and do what he mentions in the video, tending to turn, mainly because there's no trim on the 109/Buchon rudder).

So once again, Messerschmitt engineers got it right, and improved things with the tall rudder versions.

wow
thanks Sternjaeger II
nice info
