I've got 2 of these Speedybee master 3x o4 pro fpv drone so I'm selling one of them , it's got the o4pro DJI fpv camera system and 2.4elrs it comes with the o4 modular system which is transferable between the Speedybee 25 , it's full Bluetooth from an app on your phone doesn't come with GPS they around £13 plug and play , be mindful it's not a toy and you require some experience in setting it up. All boxed as it came the o4 camera and modular frame needs putting together if want to I can put it together for you just let me know.
