Being new to the Jeti family, I could use some help. Hopefully I'm posting this in the correct venue. I'm using two DS-24's for the buddy box setup and the two radios are connected via a cable. All works fine as the teacher, total control of all control surfaces and functions. When switching to the student, all the control surfaces and functions work as programed except the flaps. The flap controls are not transferring over to the student and remain with the teacher. The flaps have been set up through the Butterfly/Flap function not through the function assignment. Receivers being used are a REX 12 & 900. Any insight, help would be appreciated. Thank you. Craig
