I'm just learning to fly and decided to start with gliders (aerotow launch). However, as I joined a club its slow to build time and get experience. I was wondering if I could accelerate that with powered flight...

1) What powered flight skills could I concentrate on that would best accelerate the learning curve in the glider?

2) Would it be a better option to drive farther to get motoglider experience, or would the more nearby powered craft be just as good?

TIA,
Joel
