Description
Specific for the Gliders and other fixed-wings.       Small in form factor, It can be installed in gliders with restricted payload bays such as DLG's and high performance slopers.      Not needing to install an additional altimeter/variometer also saves room and weight.
The built in barometer provides vertical speed telemetry.      The variometer sounds both ascending and descending tones, so you will know whether you are in lift or sink without having to look at your transmitter.
with ExpressLRS firmware and CRSF protocol, this will also give you other telemetry data like battery voltage, current and GPS related.

LRS 2.4G Receiver With Seven-Channel PWM Reception.
Independent PWM Channel Output, suitable for fixed wing vehicles, ships and other models installed.
It also supports CRSF output.   The two output signals can be switched.
The PWM 6CH/7CH CRSF switch is easy to switch without rebrushing the firmware
Turn on the receiver WI-FI network,

1.   Use the lua menu of the transmitter to activate the WI-FI of the receiver when it is connected to the high-frequency head
2.   When the high-frequency head is not connected, power on for one minute, and the receiver automatically enters WI-FI
