TD-ISRM RS HF PERFORMANCE
The TANDEM X20R and X20RS versions feature solid performance based on the dual-band RF signal connection 868M/2.4G with multiple operating combinations of RF modes and are equipped with the integrated RF module TD-ISRM RS, which supports multiple protocols (such as TW, TD, etc.).
The TD-ISRM RS RF module operates in dual 2.4G TW RF mode and allows for the simultaneous activation of the TW and ACCESS R9 modes with the same module. In this configuration, the TW and ACCESS R9 receivers can be connected via the SBUS IN/OUT ports to create a redundant backup. In this solution, three different RF connections are used simultaneously in RC applications, increasing the reliability of the RF signal, especially in flight scenarios where a long range is required.

DIFFERENCES IN APPEARANCE AND FUNCTIONAL INPUTS
The X20R and X20RS have undergone a visual change compared to the original X20 design. The lower part of the grip has been adapted to the design of the PRO version, so no additional grip shells are required, and the lower part can be fully enclosed by the palm of the hand, offering a more comfortable and relaxed grip. Furthermore, the external module slot has been modified to create more space for external modules with different shapes, making installation easier.
The R and RS versions feature 2 additional trims, allowing for more precise operation. The slider levers on both sides of the transmitter provide the function to adjust the center position of the transmitter to accommodate the different habits and preferences of users. The primary controls, including trim caps, sliders, and switches, are made of metal, offering robust quality and long durability for outdoor use.

IMPROVED AND ROBUST ANTENNA HOLDER AND EXTERNAL LoRa ANTENNA CONNECTION
The new, improved antenna grip offers better resistance to shocks under the tough conditions of outdoor use. The reinforced and thickened antenna housing fits better in the hand and does not interfere with antenna performance. On the contrary, the newly designed antenna can transmit signal data more effectively, providing the pilot with more reliable flight control.
The X20R & X20RS are also equipped with 2 external antenna connectors that can be fitted with additional 2.4G and 868M antennas to enhance the RF capabilities in LoRa mode and achieve improved control over long distances.

INTEGRATED MASS STORAGE AND TEXT-TO-SPEECH FUNCTION
To spare the user from deciding on storage capacity, both the R and RS versions feature an integrated 8GB flash memory, providing enough space to meet all your transmitter's storage requirements with high data transfer speeds.
Thanks to the improved storage function, the TTS (Text-to-Speech) function of the X20 RS versions quickly and conveniently converts typed English words into spoken language. This allows the ETHOS system to flexibly adjust the triggered operational state with a generated voice tone and alert the user more clearly outdoors via the digital amplifier module.

BIDIRECTIONAL HAPTIC GIMBAL FEEDBACK
The gimbal vibration feedback can be easily activated or deactivated via a switch. The bidirectional gimbal vibration feedback can work independently on each side, allowing configuration to different feedback preferences tailored to various RC user scenarios.

EASILY ADJUSTABLE MC20R GIMBALS (with any desired angle between 45° and 60°)
The MC20R gimbal also features an 8° rotatable disc and can be set to a 45° extended position. Even better, the angle is not limited to only 45° and 60°. The MC20R gimbal allows adjustment to any desired extension position between 45° and 60°. To increase comfort for pilots during outdoor operations, the angle position can be adjusted directly with a 1.5mm hex wrench through the adjustment hole on the gimbal panel, without the need to open the transmitter case.
