Get in Touch with Thopter

Reach us by email

The one way to reach Thopter is email: support@thopter.com. Questions about a tool, a bug you hit, a correction, or an idea for a new calculator all land in the same inbox.

What to include

• Tool feedback: name the calculator — say the Drone Range Calculator or the LiPo Voltage Calculator — and what looked off.
• Bug reports: your browser, device, and the steps that led to the problem.
• Everything else:just say what’s on your mind.

What we can’t do

We can’t give personal flight-planning, legal, or safety sign-off — for that, check your local aviation authority and your drone’s manufacturer. Thopter is a small, independent, advertising-supported site, not a manufacturer or a certified training service.

How fast we reply

We don’t run a support desk, so there’s no guaranteed turnaround — but we do read everything that comes in.

Before you write

If your question is about how a number is calculated, the About page and the tools themselves usually already have the answer.
