It Is build certo well, no problema ti configura the elrs firmware with elrs configuratore, fast and easy. I want a 915 MHz version
If you don't have to update, the module works great! RC connection is very stable, even with the monopole antenna and cooling of the module through the external heatsink seems to work great.
Now for updating: the hardware for WiFi flashing and Bluetooth Joystick is there but poorly implemented. The solution BetaFPV has come up with is to just say that WiFi flashing isn't supported. Flashing through USB might not work either, depending on your luck. Some modules need to be opened and a hidden button must be pressed in order to be able to flash through USB.
So far very solid radio link. Much better than XM+. Haven't done any long range with it yet but looks promising so far
Holds a rock solid connection, and the button provides an easy way to adjust transmit power. The high gain moxon antenna markedly boosts the already good range.
Great device easy to pair
