Happymodel ExpressLRS ES915TX 915MHz Ultra Long Range Transmitter Module for Radiomaster TX16S Jumper T12 T16 T18 Transmitter
OVERVIEW:
ES915TX module is a set of long-distance 915mhz wireless transmission equipment developed and designed based on the open source software ExpressLRS. This set of modules is characterized by ultra-long range, stable operation and low latency. The module is compatible with most Opentx remote controllers, especially suitable for Radiomaster TX16S and Jumper T12 T16 T18 series remote controllers, basically plug and play. We have specially customized the heat sink for the transmitter module, which can help the transmitter module to operate stably under high power conditions.
The receiver module part is very small and exquisite, weighing only 0.70g without the antenna, which is very suitable for all kinds of Whoop fpv drone and Toothpick drone.

1. Supply power to the ES915RX, wait until the red and green LEDs on the ES915RX are off, immediately turn off the power, and then repeat again the above steps. When the ES915RX is powered on for the third time, the red LED light will start to flash quickly, which means that the ES915RX enters the binding mode
2. Insert the ES915TX module to Radio transmitter, and choose External RF mode to CRSF protocol, then you can find ELRS menu from the Radio systems, Enter into ELRS and press [Bind], the Red and Green LEDS on the ES915RX module will getting to be solid if bind successfully.
For tiny whoops weight is everything. The 75 Air frame is one option to create a light weight 75mm frame. I am enjoying mine. I migrated the motors from a Meteor65 Pro quad and use a set of 40mm propellers. Using 550 mah battery I can get a good long flight time finally.
Bought these to build a 7in 8S quad. The low kv is perfect for keeping the tip speed under Mach. These appear to be rebranded Emax EcoII, so decent quality. This quad is so powerful on 8S it's just silly. Happy Camper!
