TD-ISRM RS RF Performance

With solid performance based on the dual-band 900M/2.4G RF signal link with multiple operating combinations of RF modes, the TANDEM X20R & X20RS versions are equipped with the TD-ISRM RS built-in RF module which is capable of supporting multiple protocols (like TW, TD, etc).
The TD-ISRM RS RF module has the dual 2.4G TW RF mode and supports simultaneous activation of working under TW and ACCESS R9 modes with the same module. In this configuration, the TW receiver and ACCESS R9 receiver can be connected via the SBUS IN/OUT ports to achieve redundant backup. This RF signal connection solution makes use of three different RF links at the same time in RC applications. This further enhances the RF signal’s reliability, particularly in long-distance RC operations scenarios.

Differences in appearance & functional inputs

The X20R and X20RS have changed from the original X20 design in appearance. The bottom hand grip adopts the overall design of the PRO version, eliminating the need for an additional grip cover, and allowing the bottom part to be fully grasped by the palm for a more comfortable and relaxed grip. Additionally, the Lite-type external module slot has been adjusted to provide more fitting installation space for external modules of different shapes, making it more convenient.
R and RS versions add 2 extra trims, allowing for more precise tunings during the operations. The slider levers on both sides of the transmitter support adjusting the positioning of the center, catering to different users’ habits and preferences. The primary input components, including trim caps, center-slider caps, and knobs are all made from metal, offering rugged quality and enhanced durability for outdoor use.

Upgrade robust antenna handle & external LoRa antenna connectors

The newly upgraded antenna handle incorporates the good capability of impact resistance facing the tough conditions of outdoor fields. The reinforced and thickened antenna casing is better suited for comfort gripping but also does not compromise the antenna’s performance. On the contrary, the redesigned antenna can transmit signal data more effectively, providing pilots with a more reliable flying control experience.
The X20R & X20RS are also equipped with 2 external antenna connectors, which can be mounted with additional 2.4G and 900M antennas for enhancing the RF capabilities working under the LoRa modes, to achieve enhanced long-range control.

Built-in mass storage & text to speech function

To save the user the trouble of deciding the storage capacity, both R and RS versions have a built-in 8GB flash storage that offers big storage to meet all your radio’s storage needs with high data transmission speed.
Thanks to the upgraded storage feature, the TTS (Text-to-Speech) function of X20 RS versions can quickly and conveniently convert typed input English words into spoken speech. This enables the ETHOS system to more flexibly match the triggered operational status using generated speech audio when specific functions are activated and to alert clear outdoors with the digital power amplifier module.

Dual-side haptic gimbal feedback

The gimbal vibration feedback function can be easily enabled or disabled by setting a switch. The dual-sided Gimbal’s vibration feedback can operate independently, allowing the configuration to match distinct feedback preferences tailored to various application scenarios for RC enthusiasts.

Easy travel-adjustable MC20R gimbals (between 45° to 60°)

The MC20R Gimbals also has an 8° rotatable panel and can be adjusted to a 45° travel position. What’s even better is that the angle is not limited to just 45° and 60°, the MC20R Gimbal allows for adjustment of any travel position between 45° and 60°. To enhance convenience for pilots in outdoor applications, the angle travel position can be directly adjusted using a 1.5mm hexagon screwdriver through the adjustment hole on the Gimbal Panel, eliminating the need to disassemble the radio casing.
