I don't have my radio with me but I believe that if that if you have you Ail on ch 1 and 6, in the first menu set your aux switch for ch 6 to the three position switch and in the second menu set the flapperon option on and give it a percent. Flip the switch to see if they move. I will check when I get home but I do know you have to do two setup items, one in each menu section. I use it on all of my 50cc aerobats so I can use spoilers to assist in landing as they like to float.
