Darren showler (verified owner) –
Very nice bnf. mine had a weird jitter on forward flight but just reflashed bf4.3 and all is well. Elrs is brilliant provided u have the module u just bind and fly literally lol, feels much lighter than other 3.5inch and the range on the vtx blew me away I used a 850mah 4s and got 10mins in the air (not just round in circles i did some rippage)
100percent recommended

Very disappointed to begin with as had the same jitter as Darren, but after reflashing the FC this thing is fantastic!. Its fast and responsive (ELRS cant vouch for other protocols) and so much fun to fly.
