After leaving negative review on the Cetus X kit I want to be honest and also talk about the positive.
The drone is good. Especially for beginners. I've only used it over grass so I can't talk about how resistant to crash it but it should be. Otherwise it works, is easy to bind, configurable using Betaflight, can be updated to ELRS 3 to use on any radio. I did update it and it works perfectly. Also two sets of batteries are included, a charger, props, screwdriver, USB C adapter. You don't need anything else to make it wok. Even if in the future you may want more batteries and a charger with more slots and a storage mode (charging/discharging battery to 3.8V to avoid wear during long storage).
I only wish it was sold with the 550mAh. I only get 3 minutes of flight time with the 450mAh, a bit short.
EDIT: since then I've noticed that betafpv only published this review as it was positive and deleted the others. The review website shows that only 30% of reviews are published by betafpv, now you know how reliable they are..
Absolutely delighted with the purchase, customer service was faultless 👌🏻
Easy update firmware and conect to radio - not betafpv.
Better with 550mAh lipo batteries and lolipop video antena.
It was my first fpv drone and I'm delighted. It's the one that I would choose to start in FPV world
Resistente, ágil, divertido simplemente asombroso!!!!
