A part of the review has been auto-translated.
this unit works with access protocol. im using the older QX7. had to downgrade firmware. it works for accst. a bit expensive still
if you don't have an FR Sky radio don't buy this unit it will not work in a jumper or radio master because of the new way of binding it's not compatible with other radios
I didn't work it yet but its condition is great. Good shipping. Great support team Banggood
Awesome product
Very good
module is a lot smaller than expected, will test soon
It's a great long-haul system, but for everything to work well, you have to install the antennas properly.
It's okay.
Good Product got my drone in the air directly :)!
All great thanks
