I think im missing the point, what do you mean by "in the other direction"
for Cself ? They way I work things is that they are the same for say 40"
high coils to flat coils, inductance looks a little more with flat coils.
It looks like Cself is the same for both flat and tube coils, just confused
me with what you stated :-\
