Product overview
The RadioLink QAV250 combines a 5-inch propulsion format with CrossRace Pro flight control for FPV racing, training and high-speed aerial filming. Position-hold, altitude-hold, self-leveling and manual modes support progressive flight training, while waypoint operation allows selected routes, speeds and altitudes. Its propulsion system comprises a 55 A four-in-one ESC, 2207-1900KV brushless motors, 5-inch propellers and a 6S 1300 mAh 95C battery. The advanced version uses a carbon-fiber frame. Its 15-minute endurance, speed up to 180 km/h in position hold and 50 cm positioning accuracy are qualified by good flight-environment measurements; actual operation depends on flight conditions.
Video integration supports analog and digital configurations. CrossRace Pro incorporates an OSD chip and a digital video interface with direct connection support for DJI O3/O4 and Walksnail CADDX HD equipment. Digital ready-to-fly FPV packages include an Avatar V2 transmitter and camera, while analog packages include a 600 mW transmitter and CADDX stable camera. The Avatar HD Pro Kit configuration provides 1080P/60 fps transmission over 4 km. Avatar HD Goggles X offer a 50° field of view, adjustable diopters and interpupillary distance, and a 100 Hz display refresh rate.
Package selection determines the supplied ground equipment. The digital goggle package combines the aircraft with an AT9S Pro transmitter, Avatar goggles, battery, HOTA T6 charger, propellers, tools, straps, power cable and case. Digital screen packages include a 5-inch IPS display and Avatar FPV VRX receiver; analog viewing options include goggles or a display. Aircraft-only bundles contain the aircraft, battery, propellers, tools, straps and case, making them flight-platform packages rather than bare airframe kits. The HOTA T6 charger accepts DC or PD input and provides up to 300 W power with 15 A charging current.
