Terms
Last updated 2026-11-07. Please read these before using the tools or buying files.
Free tools
The calculators give estimates from the sizes and weights you enter, using standard methods. They are a starting point, not a guarantee. Always check the CG on your own plane, follow your plans or kit maker when they are more conservative, test carefully, and fly safely and legally. You use the results at your own risk.
Digital files
When you buy a plane you get a personal-use licence: you may print and fly it yourself, but not share or sell the files or printed parts without a maker licence. Files are delivered by email, normally within 12 hours of payment.
Refunds
Because files are digital, sales are final once the files are sent. If a file is faulty or missing, email us and we will fix it or refund you.
Safety
RC aircraft can cause injury and damage. Fly in safe, permitted places, follow your local drone and model-aircraft rules, and never fly over people.
