Overview
The UDI RC U98PRO Rear A-Arm Assembly (part number UDI-U98PRO-10) is an essential replacement or upgrade component for the UDI RC U98 Pro Mini Drone, a sophisticated 249-gram ultra-lightweight quadcopter designed for creative professionals, travel bloggers, outdoor adventurers and RC enthusiasts throughout the UK. This precision-engineered rear A-arm assembly forms a critical part of the drone's robust airframe structure, ensuring stability and durability during flight operations. Whether you're replacing a damaged component after an accident or building a complete spare drone setup, this genuine OEM part guarantees compatibility and performance with your U98PRO aircraft.
The U98PRO itself represents a remarkable achievement in portable drone design, combining professional-grade imaging capabilities with exceptional portability that makes it ideal for UK-based RC pilots who demand both quality and convenience. At under 250 grams, this brushless electric drone qualifies as compliance-exempt in select regions including the United States and European Union, meaning registration is not required in many areas. The rear A-arm assembly is engineered to withstand the rigours of regular flight whilst maintaining the precise structural integrity needed for the drone's advanced stabilisation systems and three-axis gimbal to function optimally.
RC hobbyists and professional aerial photographers across the UK trust genuine UDI RC replacement parts to maintain their equipment at peak performance levels. This rear A-arm assembly is manufactured to exact OEM specifications, ensuring perfect alignment with the drone's main body, motor mounts and suspension geometry.
Key Features
- Genuine OEM Component — This is an authentic UDI RC manufacturer part, guaranteed to meet exact factory specifications for perfect fitment and reliability on your U98PRO drone without any compatibility concerns.
- Critical Structural Element — The rear A-arm assembly forms an essential part of the airframe that directly supports the rear motor mounting points and contributes significantly to the drone's overall rigidity and flight stability.
- Lightweight Construction — Engineered to maintain the U98PRO's sub-250g weight classification, this component uses materials and design optimised for minimal mass without compromising strength or durability.
- Perfect Compatibility — Designed exclusively for the UDI RC U98 Pro Mini Drone, this part integrates seamlessly with all other U98PRO components including the flight control systems, gimbal stabilisation and motor assemblies.
- Essential Replacement Part — Whether you've experienced a crash, sustained impact damage or simply want to maintain spare components for extended field sessions, this rear A-arm assembly is a crucial part to keep on hand.
- Professional Build Quality — UDI RC components are engineered to exacting standards that support the drone's advanced flight modes, including GPS positioning, optical flow assisted hovering, waypoint navigation and gesture control functions.
Technical Performance
The rear A-arm assembly is manufactured as a precision component that integrates directly into the U98PRO's innovative airframe design. The U98PRO itself features a 1503-3400KV brushless motor system that delivers exceptional thrust-to-weight performance, enabling rapid ascent at rates up to 4.0 metres per second and controlled descent at 2.5 metres per second. The drone achieves maximum speeds of approximately 50 kilometres per hour whilst maintaining the structural integrity provided by components such as this rear A-arm assembly. The motor spacing across the diagonal is engineered at 233.6 millimetres with 64.5 millimetre diameter propellers, dimensions that require precise geometric alignment maintained by the A-arm structure. The assembly contributes to the overall chassis design that supports the 7.6-volt 2200 milliampere-hour lithium polymer flight battery, which powers approximately 32 minutes of continuous flight time under calm conditions. The drone features a built-in mechanical three-axis gimbal with electronic image stabilisation, and the rear A-arm assembly's structural rigidity is essential to ensuring this gimbal can function effectively, with controllable tilt range from negative 90 degrees to 0 degrees. The assembly is engineered to work in harmony with the drone's advanced avionics, including GPS/GLONASS positioning, time-of-flight altitude sensors and optical flow ground tracking systems that enable precision hovering even in challenging wind conditions up to approximately level 3 wind speeds.
