Professional reviewers, led by Oscar Liang, consider the Cetus X one of the best beginner kits available, highlighting its upgraded 2S power system, durable frame, and adjustable camera tilt that aid skill development. They commend the ELRS integration for range and reliability but criticize the horizontal VTX antenna, the absence of a buzzer, and the SPI-based receiver that restricts future firmware upgrades.
Everyday users overwhelmingly view the Cetus X as an excellent entry-level package, praising its durability, ease of use, and the ability to train in simulators. Common complaints focus on the very short flight time and occasional signal issues due to antenna placement, with some wishing for a buzzer for crash recovery.
Professional reviewers highlight its lightweight build, reliable 2.4 GHz control, bright goggles and useful Bluetooth simulator integration, while noting the trade-offs of analog video and brushed motors.
Everyday users love the ease of use, durability and immersive goggles, but frequently mention the short flight time and the need to buy extra batteries.
“Perfect first FPV kit”
“Perfect for my 10-year-old-easy to fly and very durable.”
“Love that it connects to Liftoff-my son practices indoors before flying outside.”
Firefly is ideal for users who want a ready-to-fly, app-enabled kit; Cetus suits those comfortable assembling separate components and seeking brushless performance.
