Owner desk
Variant check requiredOwn the Cetus X FPV Kit, not just the spec sheet.
The Cetus X is not one universal configuration. Identify whether the kit uses Cetus firmware or a Betaflight/ELRS stack before changing radios, firmware, batteries, receiver settings, or replacement electronics.
Configuration
Brushless ready-to-fly FPV system
Weight
55 g aircraft according to BETAFPV's official Cetus X aircraft page
Checked
July 19, 2026
Legal configuration
Weight changes the path. Purpose changes it again.
Different batteries, cameras, VTX hardware, antennas, and Remote ID modules change handling, endurance, and the ready-to-fly configuration.
- Recreational
- A stock 55 g aircraft can qualify for the recreational registration exception, but the flight still must follow recreational rules and applicable Remote ID requirements.
- Part 107
- Register the aircraft for any Part 107 operation, even at this weight.
- Remote ID
- A small FPV kit does not automatically include Standard Remote ID. Confirm the operating path, registration status, module weight, and FAA requirements for the exact use.
- Control stack
- BETAFPV Configurator or Betaflight Configurator, depending on the exact kit
First 30 minutes
Set it up before the launch site.
- 01
Identify the exact variant
Read the box, aircraft label, receiver, radio protocol, flight-controller documentation, and firmware path before connecting any configurator.
- 02
Charge the matched packs correctly
Use the supplied or manufacturer-approved charger and battery type, inspect every cell and lead, and never charge a damaged or puffed LiPo.
- 03
Prove modes and failsafe without props
Confirm stick direction, arming, mode switches, receiver behavior, and failsafe for the exact firmware stack before installing props for flight.
- 04
Start after simulator practice
Use a clear area, begin in the supported stabilized mode, fly close and low, and move toward manual acro only after the same control inputs are automatic in a simulator.
Compatible kit
Buy in a useful order.
Safety storage and a battery checker are safer universal first buys than guessing at a pack. The official aircraft page recommends original BT2.0 450 mAh 1S packs; confirm bay size, connector, capacity, and kit revision before ordering batteries.
Modification boundary
Do not flash firmware from a different Cetus X variant. Match the radio protocol, receiver, flight controller, VTX, motors, prop direction, connector, voltage, and battery capacity to the exact kit.

Maintenance rhythm
Keep small problems small.
- Before every pack
- Check propellers, guards, motor shafts, antenna, battery retention, camera angle, video link, controls, and failsafe.
- After any crash
- Disarm, disconnect the packs, inspect the frame and motors, clear debris, and test at low power before another full flight.
- Every session
- Log damaged packs, retire puffed or punctured LiPos, and return reusable packs to storage voltage with the correct charger.
- After firmware or radio changes
- Recheck stick direction, arming, modes, failsafe, video, receiver behavior, and motor order in a controlled area.
Symptom to decision
Troubleshoot without guessing.
The radio will not bind
Confirm Cetus versus Betaflight/ELRS variant, exact radio protocol, receiver mode, firmware target, bind procedure, and antenna condition.
Do not flash a guessed target or fly with an intermittent receiver link.
The quad flips on takeoff
Disarm immediately and verify propeller orientation, motor direction, motor order, flight-controller orientation, and accelerometer setup for the exact firmware stack.
Do not keep adding throttle to diagnose a flip.
Video is noisy or disappears
Confirm goggles channel and band, inspect VTX and antenna connections, keep the antenna attached before power-up, and test at low power nearby.
Do not fly behind obstacles or beyond a link that has not been proven close and clear.

What the BETAFPV Cetus X FPV Kit is
The Cetus X is a complete brushless analog FPV package intended to bridge stabilized beginner flight and manual acro practice. Exact firmware, receiver, radio, battery, and parts compatibility depends on the kit variant.
This page is organized around setup, legal configuration, exact-fit parts, maintenance, troubleshooting, and current official support. It is not presented as a hands-on Drone Authority review.
If you plan to shoot with it, the camera settings and moves that get the most out of its footage are our sister site Aperture Authority's beat: see their guide to drone photography and video.

Aircraft to operation
Before first launch
Buying the aircraft is one decision. Use this sequence to get from the box to a deliberate, legal first flight.
Aircraft under consideration
BETAFPV Cetus X FPV Kit
- 01Check registration
Aircraft status
Set the registration path
Confirm BETAFPV Cetus X FPV Kit's takeoff weight and your operating purpose. Recreational and Part 107 flights follow different registration paths.
- 02Start the airspace check
Launch location
Check the exact airspace
The aircraft does not decide whether a location is clear. Check the launch point, planned altitude, date, and time for controlled airspace, restrictions, and local launch rules.
- 03Check commercial requirements
Only when it is work
ConditionalDecide whether Part 107 applies
A small drone does not create a business-use exception. If the flight serves a client, employer, listing, monetized project, or another non-recreational purpose, check the Part 107 path first.
- 04Open the first-flight checklist
Props still off
Run the first-flight preflight
Confirm aircraft condition, firmware, battery health, controller link, home point, return-to-home settings, weather, people, obstacles, and the lost-link plan before takeoff.
