Receivers in this category pass control signals from a transmitter to the servos on a model, and their telemetry lets the pilot monitor voltage data from the transmitter.\u003c\/p\u003e\n\u003ch3\u003eWho It's For \/ Use Cases\u003c\/h3\u003e\n\u003cp\u003eGlider and fixed-wing pilots who want a compact receiver with several servo outputs and telemetry are the typical buyers for this type of unit. Pilots whose competitions ban variometers, or who simply do not need one, may prefer a receiver without the built-in sensor.\u003c\/p\u003e\n\u003ch3\u003eHow to Use \/ Care\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003ePower the receiver from a 1S LiPo receiver battery, which the product description lists for both the ER8G and ER8GV.\u003c\/li\u003e\n\u003cli\u003eChoose the version that fits your build: the ER8G has the same functionality as the ER8GV without the built-in Vario, which suits competitions that prohibit Vario.\u003c\/li\u003e\n\u003cli\u003eUse the receiver with ExpressLRS 3.3.0, which is pre-installed on the unit.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eHow to Choose\u003c\/h3\u003e\n\u003cp\u003eStart with whether you need a built-in Vario sensor, since the ER8G and ER8GV differ on that point. Next, check that your flight battery setup falls within the listed voltage detection range in Product Specifications. Finally, count the servo outputs your model needs and confirm the 20cm antenna suits your airframe layout.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this receiver include a battery?\u003c\/strong\u003e\u003cbr\u003eNo. Batteries are not included, and the unit runs from a DC 3.5 - 8.4V power input listed in Product Specifications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich version has the Vario sensor?\u003c\/strong\u003e\u003cbr\u003eThe ER8GV has a built-in high-precision air pressure sensor (Vario). The ER8G uses the same functionality without that sensor, so it suits competitions that prohibit Vario.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow many servos can it drive?\u003c\/strong\u003e\u003cbr\u003eThe receiver can drive up to 8 servos and supports 8 PWM channels, with a compact and slim design for glider pilots.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the telemetry power adjustable?\u003c\/strong\u003e\u003cbr\u003eTelemetry power reaches a maximum of 100mw and is adjustable through LUA.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does voltage telemetry choose the input?\u003c\/strong\u003e\u003cbr\u003eThe receiver detects which voltage input to use automatically, and only one voltage input can be used at any given time.
