I'm not aware of Greatplanes having a 1/4 Scale Cub, is this something new? There .60 size Cub is not quite 1/4 scale. I believe they list it as 1/4.7 scale. That may be why no one has replied. I'm sorry to say I haven't flown any of the Greatplanes Cubs, only the Goldberg Cub, which I believe is somewhere around 1/5 sort of scale.
