On stock firmware, this is 2-star at most. It is essentially the same as 2.4ghz Access/ACCST, just moved to the 900mhz band. As such it only offers a modest improvement on the less than stellar range of the 2.4ghz version; still significantly behind Crossfire. However, if you flash it to ELRS it performs quite well. The only wrinkle is that it cannot beacon a wifi signal for configuration, so you will have to use the ELRS configurator for anything you can't set via the LUA script.
