I've never tried to trim it for gliding - but I don't think it would.

My younger boy burned through a bunch of B4 and B6 motors in it one day at a club launch. I don't recall if it was TWA or WOOSH. Prep. Fly, Recover. Repeat.
I saw that one back then--and it's a model of the original Pegasus, no less (whose tail assembly [unlike the Pegasus XL's, whose tail fins are spaced 120 degrees apart]) is a conventional airplane-type one, which is "poorly configured" as a rocket tail assembly, yet your model still flies--vertically, as a ballistic rocket--stably. A gliding Pegasus model, if built larger but lighter (with a lower wing loading), might glide well, if fast. (As numerous YouTube videos show, many of the RC pulse jet model airplanes--low leading-edge sweep subsonic-type delta flying wings and semi-scale Heinkel He-162s are popular pulse jet models--glide quite fast after their engines cut out, but with low sink rates, even just before landing.)
