My Champ is not scale. It is the old DeBolt Champ, which was a slightly Champ-like trainer. You can see it in my gallery.

Full scale Champ--nice! The only current Champ kit I know of is a little 35 inch electric from Hobby Hangar, and even it may have been discontinued recently.

Your Cub was originally designed by Chuck Hollinger in the early days of RC. Cal Smith was inspired by that plane to design a scale Champ using similar construction, and to the same 1/6 scale. It is available from AMA Plans Service, and there are probably other Champ plans there too. Bill Northrup also has the Cal Smith design--see recent mags like Flying Models for ads.

You really should try scratch building--it's not that hard. The toughest part on the Champ is that distinctive curved windscreen.
