you don't have to have plans. Here is a couple I built from scratch and they fly great. The red one I call the TRICK STAR has a Norvel .061 and will fly any AMA manover in the book and is light as a feather and tough as nails. The yellow and turquoise I call the SWEAT BEE and is powered by a Cox Black Widow .049 and is a real hot rod! It flys a bit fast but has good line tension and is very managable.
