I'm somewhere in between.
I have my students self study and use the (((King videos,)))
I do 3 full on long ground sessions, a ground for weight and balance, for the initial cross country and a mock oral.
I don't charge for these if the student picks it up within a normal pace, which most do.
If I have to repeat any of those three, or someone needs a abnormal amount of time during one, or they need me to hold their hand for ground, I charge.
For the short pre and post flight brief, I don't charge and I don't spend much time, if I tell you were going to do turns around a point, you should have already read up on the maneuver, know the tolerances and the basics behind it.
$50 air / $50 ground. Cash or trade only.
