What Oscar Liang's Website Is About

Updated

Oscar Liang (oscarliang.com) is a blog for FPV drone pilots and RC hobbyists, built around two things: practical tutorials and hands-on product reviews. If you fly quadcopters or multirotors and want to learn how to build, tune, or troubleshoot them — or want a hobbyist's opinion before buying gear — it's aimed at you. If you're looking for a store, a course platform, or general consumer drone news, it isn't that.

What the site covers

The site describes itself as "FPV Drone Tutorials and Reviews, a blog for RC hobbyists to get latest information about quadcopter and multirotor products and technology development." In practice that breaks down into:

  • Tutorials — how-to guides for FPV work, including tool use and testing procedures.
  • Reviews — evaluations of specific products, often receivers, video transmitters, and flight controllers.
  • Reference material — charts and technical explainers, such as FPV channel and frequency tables.
  • Technology news — updates on multirotor products and development.

Who writes it and who it's for

The blog is written by Oscar Liang and published in English (en-GB). The stated audience is RC hobbyists, with a focus on quadcopter and multirotor pilots. The tone and subject matter assume you're already in the hobby or getting into it — you'll get more out of it if you know what a receiver or a flight controller does than if you're shopping for a first camera drone.

Examples of the content

Recent posts give a clear picture of the mix:

The multimeter tutorial is a good sample of the approach: it treats a cheap, basic tool as essential kit for anyone getting into FPV or electronics, and walks through how to use it to test a drone. That's the pattern — specific, tool-and-component level, written for someone who already owns or is about to own the hardware.

When it's worth following

Follow it if you want:

  • Step-by-step help with FPV hardware, testing, and builds.
  • Reviews of specific components before you buy.
  • Technical reference data you'll come back to (like frequency charts).

Look elsewhere if you want beginner-friendly buying advice for consumer camera drones, video-first content, or a structured course. The site is a blog, so expect articles rather than a curriculum.
