Sorry, I got the Spectra and Spirit confused there.

Since your Spectra is powered just treat it like a power model as far as the instruction goes. The only difference being you have to walk it out and handlaunch it. Later, when you're comfortable with the actual flying duties, try learning to soar with it. Who knows, perhaps you'll start a whole new trend in your club when they see you get your first 1/2 hour flight out of a single 60 to 90 second climb.
