License Agreement

1. What you may use the files for

Buying a design gives you a personal, non-transferable licence to use it for your own private, non-commercial flying and building. You may print as many copies of the aircraft as you like for yourself.

The licence does not cover use by a company, school, university, club, research institution, or any other organisation, including unpaid use, and including classroom or teaching use. If you want to use a design in any of those settings, get in touch and we will agree separate terms.

2. What you may not do with the files

You may not:

• Pass the files on to anyone else, whether or not you charge for them.
• Upload them anywhere others can download them, including model-sharing sites, forums, cloud drives, and chat servers.
• Include them, in whole or in part, in anything you sell or give away.
• Sell prints of the designs, or run a business printing them for other people.

The one exception is individual STEP files, covered in clause 4.

3. Changing a design

Modify the designs as much as you want for your own use: scale them, remix them, cut them up, fit them to whatever electronics you have. The result is still covered by this licence, so a modified design stays between you and your workshop unless clause 4 applies.

4. Sharing modified STEP files

Individual STEP files are the exception to clause 2. If you have modified one, you may share that file, provided you credit the original. This covers single component files only. You may not share a full design, a complete file package, or enough parts to reconstruct one.

Credit needs to name BuildingRC as the original author and say where the original came from, without suggesting we endorse your version. Something like:

“Original file created by BuildingRC, available at buildingrc.com. Modified by [Your Name].”

5. Aircraft you print

Aircraft printed from these designs are for your own recreational flying. Please do not set up a business producing or selling them, and do not use them commercially or on behalf of an organisation. If you want to do any of that, contact us about a commercial licence.

6. Who owns the designs

Copyright in the designs and files stays with BuildingRC. You are buying a licence to use them, not the designs themselves. Nothing here takes away rights you have under applicable copyright law, and nothing here is meant to stop you talking about, photographing, or filming aircraft you have built.
