What model BeastX do you have? If its the regular BeastX (NOT the AR7200) it will work with most regular receivers. Also what receiver do you have? Some walkera receivers do not work with beastx because they are not standard. At any ate to test, In receiver setup you would need to select "standard receiver" and connect it up as you would any other receiver. Lets find out the above first then we can go through and see what we can do..
