Perfect, tested to 5 km only once failsafe because of strong interference
I have had a really great experience with their version of ELRS. The Tx modules and the RX modules have all worked great for me. I also really like the version 2 and 3 controllers with ELRS built in.
Really nice product for that price, just a problem, sometimes when switched on elrs module it didn't bind with rx, then i restart the drone and everythings working
I am using both 900mhz and 2.4ghz. These work well with Frsky lite transmitters with edge tx loaded.
