Such effects strongly correlate with the level of forces generated in the particular aircraft under the microscope. I would expect to see much the same sort of effect with a higher powered piston machine - the airflow goings-on are going to be much the same ....
Can't say that I have ever noticed the effect but that may just be a reflection on my inadequate handling sensitivity competence ?
never personally noticed one any aircraft type.
Knowing zzuf well in a past life and holding his handling competence in the highest regard, I am surprised to hear that a chap of his background hasn't observed the effect ... makes me feel a little less inadequate ....
Sorry to disappoint JT - it wasn't for the lack of trying. As you know, I must have done a few hundred high crosswind, narrow runway takeoff tests, in more than a dozen aircraft types. Probably thinking too much about the upcoming engine failure, and knowing with such crosswinds Vmcg was a figment of ones imagination!
