The iFlight Protek R25 is built with a 2.5" Cinewhoop with analog transmission, suitable primarily for capturing breathtaking footage from an external HD camera. Due to its covered propellers and small dimensions, it is especially suitable for flying indoors, but it can also fly outdoors without any problems. 2.5" Cinewhoop is suitable for carrying lighter cameras like Insta360 Go or Naked GoPro. The copter also includes a 3D printed camera holder. An ELRS receiver is installed in the copter, but it is not a problem to replace it with another one.
