A beginner glossary for FPV terms like ELRS, VTX, RX, FC, ESC, BNF, PNP, RTF, LiPo, and Betaflight so product pages make sense.
FPV vocabulary can make a beginner feel locked out of the hobby. The trick is not memorizing every term at once. Start with the words that decide compatibility. If a term helps you avoid buying the wrong radio, receiver, battery, or drone, learn that term first.
Buying Terms
| Term | Plain meaning | Why beginners care |
|---|---|---|
| RTF | Ready-to-fly kit | Usually includes more of the setup |
| BNF | Bind-and-fly drone | Needs compatible radio and goggles |
| PNP | Plug-and-play aircraft | Often needs your own receiver |
| ELRS | ExpressLRS radio link | Radio and receiver must match |
Drone Electronics Terms
FC means flight controller, the board that reads sensors and commands the quad. ESC means electronic speed controller, the part that drives motors. VTX means video transmitter, and RX usually means receiver. Once these four terms make sense, product pages become much less intimidating.
LiPo refers to the battery type used by most FPV quads. LiPo knowledge matters because charging, storage voltage, cell count, and connector type affect both safety and performance.
Where the Terms Show Up
When comparing RTF and BNF FPV drones, look for receiver protocol, video system, battery connector, and included accessories. When choosing RadioMaster FPV radios, check ELRS support and simulator connection. For repairs, categories such as FC and ESC stacks, FPV video transmitters, and FPV receivers and ELRS RX gear are where acronyms become actual parts.
Mini Translation Habit
- Underline every acronym on a product page.
- Translate it into a compatibility question.
- Check whether the answer matches your existing radio, goggles, and batteries.
- Only then compare price or shipping.
