I had one of those sitting around. I thought it was a weak .46. I finally built a profile around it. I got plans from RCM ("Dart Cart II, by Joe Birdi) I modified things, but kept the basic plane. It was very easy to build. My total fly weight came in at 4lbs. There are resources out there for kits and arfs

Another choice, not a profile:

Good luck.
