Small, lightweight 6-channel 2.4GHz ACCESS and ACCST D16 telemetry receiver with S.BUS input and output ports (up to 24 channels). Integrated precision vario. Black box for preserving basic flight data. Smart automatic pairing. Wireless firmware updates. Weight 4.2 g; dimensions 33×15×9.7 mm.

Advanced 6-channel 2.4GHz telemetry receiver for ACCESS and ACCST D16 RC protocols, with 6 high-precision PWM channels and 16 or 24-channel S.BUS modes. Two detachable antennas with IPEX4 connector provide full signal strength throughout the range. It's especially ideal for gliders, but you can use it for various other models as well. Thanks to its size and low weight, it is also suitable for small models. With redundancy support, it can be connected as a primary receiver via S.BUS. Thanks to the F.BUS connection option, you can also pair it quickly and easily to several different telemetry devices.

It features advanced anti-interference protection for reliable and stable signal transmission across the entire range. Smart-match system speeds up pairing. The black box function preserves basic flight data. LED indicates the receiver's operating status. A Smart matching function allows firmware updates wirelessly.

It is equipped with a variometer that provides more accurate and faster measurement and transmission of altitude and vertical speed data. It also allows quick audio feedback from the variometer to the ACCESS transmitters.
