The models in this section represent reproductions of the old Carl Goldberg rubber powered Free Flight models. The design of the parts included tabs and slots that helped insure that each part could only fit one way during the assembly of the model. The Goldberg sheet balsa models did not have color printed on the parts. They included water slide decals and were intended to be decorated with color dope. Like the Jigtime models, the Goldberg sheet scale models were also great flying rubber powered models.

The models shown here along with the plan packages are a best attempt to reproduce the original series in their original form. Each plan package includes a scan of the original kit plan along with some building notes. All of the plans are in the Adobe PDF format. Each package containing multiple pages that are printed on U.S. legal size paper (8.5" x 14"). A link is provided with each model description to download the associated plan package. WHEN PRINTING MAKE SURE THAT PRINT SCALING HAS BEEN TURNED OFF.


A description of the method used to print the parts directly on balsa is provided here. Just click on the link.


NOTE - A very good alternative to printing the parts for these models directly on balsa it to use T-shirt iron-on transfer paper. This material comes in 8 1/2" x 11" sheet size and works very well for transferring the drawn parts to balsa. A summary of the process for doing this is covered here. The major advantage of using this process is any printer can be used. To make it a bit easier to use iron-on transfer paper to create the full color parts for these models an alternate parts drawing package is provided. This drawing package has been laid out for 8 1/2" x 11" sheets. A link to the iron-on transfer package is provided in each model section of this page.


If you have access to a 3D printer, you will find some 3D print files for propellers here. The 6 1/2" or 7" prop are well suited for these models.
