The UDI Peregrine is a 156 mm sized drone. It is similar to the Recon FPV in that it can perform flips and the camera can can store video at 720P resolution for display on a PC via the supplied memory card and card reader. The difference is that rather than use a built-in screen to dsplay the camera’s image in real time it is linked to a mobile phone or pad using a special iOS or Android app.
