Kefer,
A TD or Black Widow on a power would ideal for a 2 meter glider. This set up lets you use it as a conventional glider as well.
I used one on a Gentle Lady to learn to fly. You can definitely get a GL into thermal territory this way! My friend and RC teacher back in the day took my radio away from me so he could get the GL out of a nice thermal just before it disappeared[sm=shades_smile.gif]
