DarwinFPV Baby Ape FPV Drone

Barely flown Darwin Baby Ape II with Foxeer Lollipop 4+, Spare motor, and Mini-Star 4S 650mAh. Pretty sure the quad has a broken flight controller. I tested it with both a new camera and the VTX, and it will still only show grey screen with OSD, so it needs some fixing. Willing to negotiate price.
