Most Air Movement on Planes Surface??
OK.If a plane is moving 100 MPH where is the most air movement??. On the wings are in the prop wash??
I'm trying the I4C air whistles and wondering where to put them where they will get the most air passing.
I put some on the bottom wing tips of my Shrike and have another set.I haven't tried them yet so if they don't work that well I'm wondering where else to put them.
Thanx
