Any of the Ugly Stik clones make excellent second planes. I have a Thunder Tiger Stick that has been put through the mill and it is still going strong. Needless to say, the stick-on covering leaves a lot to be desired but it held up well for three (3) years before needing to be replaced. When I stripped the old covering off, I was pleased with the workmanship that I found on the airframe. I found one place that the leading edge sheeting was not adequately glued to a rib. Other than that, it was structurally sound.
