The Skybolts a great plane. I just finished mine up, and have flown it a few times. It is not like your typical Ultimate either, it is a nice looking plane. Mine is powered by a Saito 100. It is very possible that you might need nose weight on this plane, so a 1.20 might be a good choice. The 100 is more then enough power however. If you build the plane, youve gotta put smoke in it. It looks awesome when in the air!!! Here is a picture of mine on the ground:
