Key Features

• Dual Antenna Design for Extended Range — The dual antenna configuration provides exceptional signal strength and redundancy, ensuring stable control even in areas with potential RF interference, which is particularly valuable when flying in urban environments or near other wireless devices across the UK.
• 6km Transmission Distance — With an effective range of approximately 6 kilometres in interference-free and unobstructed conditions, this remote controller allows you to operate your drone far beyond standard RC toy limitations, enabling ambitious aerial cinematography and exploration flights that would be impossible with conventional systems.
• Operating Frequency Band — The transmitter operates across 5.15-5.35 GHz and 5.725-5.825 GHz frequency bands, these are internationally recognised bands that provide reliable, long-range digital transmission without the interference issues common to older 2.4 GHz systems.
• Integrated Smartphone Holder — The remote controller features a built-in mobile phone holder accommodating smartphones up to 7 inches, allowing you to view real-time video feeds, access the UDIRC-X app for advanced flight settings, and monitor telemetry data directly from your device during flight.
• Built-in 7.4V 1500mAh Rechargeable Battery — The transmitter includes an internal rechargeable lithium battery providing approximately 3 hours of operation time, with a convenient 1-hour charge time via USB Type-C connectivity, ensuring you can keep flying throughout the day.
• USB Type-C Charging — Modern USB Type-C charging eliminates the need for proprietary charging cables, allowing you to charge your transmitter using the same cable as most contemporary smartphones and tablets, enhancing convenience for travelling RC pilots.
• 5G WiFi Real-Time Video Transmission — The controller transmits real-time video feeds at 720P resolution at 20 frames per second via 5G WiFi, providing live FPV-style footage on your smartphone screen so you can see exactly what your drone's camera is capturing.
• UDIRC-X App Integration — Compatible with the UDIRC-X app for both iOS 9.0+ and Android 4.4+, the transmitter unlocks advanced features including waypoint flight planning, follow-me modes, surround orbit control, gesture photo/video activation, and comprehensive flight telemetry monitoring.
• Precision Control Interface — The remote controller features intuitive joystick controls for throttle, yaw, pitch, and roll, alongside dedicated buttons for flight mode selection, return-to-home activation, camera controls, and gimbal adjustment, providing the tactile feedback serious RC pilots demand.
• Signal Loss Auto-Return Protection — Should the control signal drop due to exceeding range or interference, the drone automatically initiates a return-to-home sequence, navigating back to its launch point autonomously and protecting your valuable aircraft investment.
• Out of Range Alarm System — The transmitter provides audio and visual warnings as your drone approaches the maximum control range, giving you time to adjust your flying pattern before signal loss occurs, enhancing safety during extended-range operations.
• Low Battery Alarm and Emergency Hover — Real-time battery monitoring alerts you as your drone's power depletes, and the system engages emergency hover mode to safely land your aircraft when battery levels become critical, preventing loss of aircraft due to power failure.

Technical Performance

The UDI RC U98PRO Remote Controller represents a sophisticated piece of RF engineering designed to command advanced aerial platforms with precision and reliability. Operating across dual frequency bands (5.15-5.35 GHz and 5.725-5.825 GHz), the transmitter achieves approximately 6 kilometres of reliable control range under optimal conditions, with dual antenna technology ensuring signal redundancy and resistance to RF interference common in populated areas across the UK. The 2.4 GHz frequency band that powers the drone communication (separate from the transmitter's primary control frequencies) is a globally standardised band utilised across millions of consumer and commercial RC devices, ensuring compatibility with international regulatory frameworks.

The transmitter is powered by a built-in 7.4V 1500mAh rechargeable lithium battery, providing approximately 3 hours of continuous operation time—sufficient for multiple flight sessions when combined with the drone's 32-minute maximum flight time per battery. The USB Type-C charging interface supports 5V 2A input for rapid charging cycles of approximately 1 hour, and the integrated smartphone holder (accommodating devices up to 7 inches) serves dual purposes: viewing real-time video feeds and accessing the comprehensive UDIRC-X application for flight mode selection, telemetry monitoring, and advanced autonomous flight planning.

The control electronics support multiple simultaneous protocols and signal types, including GPS positioning verification, GNSS (Global Navigation Satellite System) using both GPS and GLONASS satellites for accurate location tracking, and time-of-flight sensor integration for altitude-hold stabilisation. The transmitter communicates with the drone's 1503-3400KV brushless motors and three-axis stabilised gimbal system through digital transmission protocols, enabling direct control over motor thrust vectoring, camera pan-tilt-roll adjustments, and advanced flight modes including cruise control, waypoint navigation, and follow-me tracking with subject-locking algorithms.
