Futaba 4GRS 2.4GHz FHSS/S-FHSS + R304SB receiver

Description

Fully expanded 4-channel RC car transmitter of the upper performance class, with integrated telemetry function in 2.4 GHz T-FHSS technology.

The 4GRS offers an extremely precise and direct control feeling - experience the new high-speed control feeling with the ultra-fast control of digital servos with only 2.9 ms.

Combined with features that leave almost nothing to be desired and the well-known Futaba quality, this makes the 4GRS the perfect transmitter for demanding RC car and racing boat pilots who don't like a pistol grip system. The Futaba FHSS frequency hopping technology offers high transmission reliability.

The transmitter housing is ergonomically balanced and features practically positioned controls.

A large, centrally located 128 x 64 dot graphic display with backlighting ensures good legibility in all lighting conditions. The graphical user interface, with the easy-to-understand Futaba menu structure, ensures fast operation.

Navigation is via the intuitive 4-way rocker key in conjunction with 2 additional keys. Side-mounted rotary encoders and switches allow the operation of additional functions, even during the race.

Features

Highlights :

• 4-channel telemetry system T-FHSS
• Real-time display on large screen
• Alarm tone setting and output
• Automatic, timer-controlled telemetry data recording
• 65 x 32.5 mm large, backlit display (128 x 64 dot)
• Normal servo outputs and S-BUS technology for fully digital integration of S.BUS servos, S.BUS controllers and S.BUS sensors
• Fully equipped 4-channel transmitter with 9 control elements, largely freely assignable Ultra-fast control of digital servos with only 2.9 ms.

Transfer :

• 4 control channels in 3 switchable modulation modes
• FHSS, 4 control channels without telemetry
• S-FHSS, 4 control channels without telemetry
• T-FHSS® 4 control channels and 4 telemetry channels
• High immunity to interference due to 2.4GHz frequency hopping modulation
• Up to 100 mW transmission power
• Real-Time-Response - Real-Time Control
• The response time (from stick actuation to servo reaction) of the FHSS system is significantly faster than other 2.4 GHz systems.
• Long range
• Ultra-fast, direct, continuous digital modulation for the shortest response times
• Switchable T-FHSS high-speed mode for ultra-fast control of digital servos with 2.9 ms (14 ms in normal mode)
• Easy Link - extremely simple, fast binding method between transmitter and receiver
• Extremely fast and safe automatic re-binding even under difficult conditions
• Intelligent servo timing for even servo control and prevention of servo runtime differences
• No loss of reaction speed even with a heavily occupied frequency band

Note: Future-proof according to EU standard EN 300 328 V1.8.1.

The current Futaba telemetry transmission systems FASSTest and T-FHSS already comply with the new EU standard EN 300 328 V1.8.1. It is not necessary to adapt these advanced transmission systems to meet the new EU standard. FASSTest and T-FHSS are 100% future-proof.

The FASST and FHSS transmission systems will be adapted to the new EU standard in the software on channels sold from 1 January 2015. This adjustment ensures compatibility with all existing Futaba FASST and FHSS components. All channels purchased before 1.1.2015 may continue to be used anyway. This means that FASST and FHSS also offer the user safety through compatibility of all components.

Telemetry :

• Synchronized, bidirectional communication between transmitter and receiver with high telemetry data rate (up to 9 times per second)
• 4 telemetry channels
• Alarm tone setting and output
• Automatic, timer-controlled telemetry data recording
• Real-time display of telemetry data on integrated display
• Receiver signal strength indicator to monitor range
• Receiver undervoltage warning system for monitoring the receiver battery
• Connection of sensors to the S.BUS2 input for: voltage of the battery (0-70V-DC)
• Speed (optical, magnetic or with BL sensor)
• temperature (125°C or 200°C)

S.BUS Technology :

• Receiver R304SB with four normal servo outputs and one S.BUS connection for fully digital integration of S-BUS components such as S.BUS servos, S.BUS controllers and S.BUS sensors
• All S.BUS servos can also be connected to normal servo outputs of the receiver
