FlySky has released a tiny Express LRS receiver that matters to Uav builders hungry for choice. It’s compact, 100mW, and signals FlySky’s serious move into ELRS hardware.
TL;DR
PR01 is a 1.2g ELRS receiver from FlySky with dual flat antennas, CRSF/SBUS output, and 3.5–9V support. It’s listed in the ELRS configurator and comes with a few initial update quirks.
What is the PR01?
The PR01 is FlySky’s first small-form Express LRS receiver offering antenna diversity. Painless360 spotted it immediately after the PA01 radio debut.
Specs at a glance
Key numbers are short and useful for Uav builders choosing parts.
- Transmission: 100 milliwatt
- Antennas: two flat antennas (diversity)
- Voltage: 3.5–9 V DC
- Outputs: CRSF or SBUS
- Weight: ~1.2 g; Size: 18 × 18 × 3.7 mm
Why this matters for Uav builds
More ELRS-compatible receivers mean more swapping and cheaper test rigs for Uav projects. FlySky entering ELRS increases competition and parts availability.
Form factor and antenna choices
The PR01 uses flat antennas. They keep the profile low but divide opinion among pilots and makers. Painless360 admits a personal dislike, yet acknowledges many prefer flat elements.
Configurator listing and variants
The ExpressLRS configurator already lists FlySky receivers — two models in the database. One listed unit likely uses traditional wire antennas rather than flat ones.
Initial user experience—updates and Wi‑Fi
Painless360 ran into update and Wi‑Fi configuration issues with the PR01. Usual tricks didn’t work, which suggests firmware or tooling teething problems.
What to expect next
Expect FlySky to publish firmware and documentation; expect more receiver variants soon. The author promised follow-up tests once updating and the Wi‑Fi app behave.
How this affects your Uav project choices
If you build Uavs, add PR01 to your shortlist for small builds and bench testing. Wait for firmware stability if you rely on the Wi‑Fi configurator today.
Where to find it
Painless360 will link the official FlySky page once available; configurator entries already hint at product SKUs. Keep an eye on FlySky’s site and the ELRS configurator for release updates.
FAQ
Is the PR01 compatible with CRSF radios?
Yes. The PR01 outputs CRSF and SBUS, so it should bind to CRSF-capable radios via ExpressLRS.
Will the flat antennas reduce range for Uav flights?
Flat antennas trade profile for potential pattern changes. They still provide diversity, but test range before critical flights.
Can I update firmware over Wi‑Fi right now?
At time of reporting, the author hit issues updating via Wi‑Fi. Firmware updates may require USB or updated tooling.
Final notes
FlySky joining the ELRS ecosystem is good for the Uav community — more options, more parts. Expect minor teething issues, then wider availability.
Takeaway
- FlySky’s PR01 brings a tiny ELRS receiver to Uav builders — 100mW, dual antennas, CRSF/SBUS.
- Flat antennas keep the profile low; some pilots prefer wires — test your use case.
- Firmware and Wi‑Fi tooling showed early hiccups — wait for stable updates before trust flights.
- Configurator listing shows at least two FlySky ELRS receivers — more choices incoming.
- PR01 weighs 1.2g — ideal for tiny Uav rigs that hate excess grams.
- Check ELRS Configurator for FlySky entries before buying.
- Test range and binding on the bench — don’t assume Wi‑Fi updates will work first try.
