A growing suite of physics-based tools for drone builders. Real numbers, real parts, honest answers, starting with a free build calculator.
Born from a real need: building a demanding drone where the numbers had to be right, not "close enough."
PropDesk started as the toolkit an engineer wished existed while building a serious machine, where a wrong calculation means a burnt ESC, a failed flight, or worse. No marketing numbers. No guessing. Just real physics and honest data. Now those same tools are here for every builder who takes their craft seriously.
Physics-based instruments for every stage of your build.
Analyze any build, design from your goals, or search real parts. Get T/W ratio, true endurance, hover thrust margin and ESC safety warnings, instantly.
Set your goal and budget. The tool searches real components for the combinations that hit your targets, ranked by price, balance and safety margin.
Check whether your chosen components work together before you buy: voltage, current, mounting and connector compatibility, flagged early.
Projects is where builders document their work. Keep a build diary as your machine evolves, publish it when it's done, and grow a public portfolio. Browse other builders' finished projects and learn from real builds, not just specs.
One burnt ESC costs more than a year of Builder. Start free, upgrade when ready.
Unlimited builds, saved builds, comparison, PDF export.
Everything in Builder, plus the Cost Optimizer and early access to new tools.
In development: Compatibility Checker. It is not part of what you are buying today. We'll only list it above once it ships.
PropDesk is fully functional for early users while we finish the legal groundwork for a proper public launch: terms, privacy, the boring-but-important parts. Leave your email and you'll be the first to know.
We'll only email you about the launch. Nothing else.
