There were the large, heavy radio controls, with lots of switches and buttons. But this was before. From now on, the multirotors hold in their hands, and the radio controls also follow a slimming diet. The manufacturer Radiolink offers a new small format 2.4 GHz radio: the T8S. Like its competitors at FrSky or Flysky, it adopts a gamepad look, rather refined. It is based on the same chipset as the FrSky Taranis X9D, but Radiolink ensures that the throughput is 3 times faster, and adopts the same FHSS protocol as the AT9S remote control. It offers 8 channels and a transmission power of 100 mW.
The T8S measures 116.2 x 9.55 x 5.7 cm and weighs 142 grams. It offers 2 joysticks, 4 trim keys, 2 switches with 2 positions and 2 switches with 3 positions. Its integrated, non-removable battery is a 900 mAh Lipo 1S that charges with a microUSB cable for an autonomy of about 5 hours. It is compatible with the receivers R7FG, R8F, R6FG, R6FG, R6G, R8EF and the small R8FM, which weighs 2.5 grams and measures 1.6 x 2.15 x 1 cm, with the support of SBUS and PPM. The pair offers a range of 2 kilometers, according to Radiolink.
On the front panel, there is only one battery status indicator. No screen, therefore, to manage the settings. How do I configure the remote control? The manipulations are based on a smartphone application (only for Android at the moment), with a USB cable connection – Radiolink provides an OTG cable for this. The interface allows basic settings, calibration, but also more advanced mix functions. Updates are possible, via a PC under Windows. The radio is available in mode 2 (gas on the left) and mode 1 (gas on the right), but the manufacturer does not indicate whether the choice of mode can be made freely.
