This is what you need to do from the drawing 1: You will need to add another Drawing 2 circuit AND add 3 4017 and 1 4081 circuit as in the drawing for the left wing but follow the connections below. BASICALLY DOUBLE both drawings but you will only need (1) ONE SX28 as the left wing will connect to RC outputs and RA.1. Add J4 (like J1) and J5 (like J2) and reverse the wires from J1 and J2 for the "left" wing. J4-1 4017(3) pin 7 J4-2 4017(3) pin 4 J4-3 4017(3) pin 2 J4-4 4017(2) pin 9 J4-5 4017(2) pin 6 J4-6 4017(2) pin 5 J4-7 4017(2) pin 1 J4-8 4017(2) pin 10 J4-9 4017(2) pin 7 J4-10 4017(2) pin 4 J5-1 4017(1) pin 2 J5-2 4017(1) pin 9 J5-3 4017(1) pin 6 J5-4 4017(1) pin 5 J5-5 4017(1) pin 1 J5-6 4017(1) pin 10 J5-7 4017(1) pin 7 J5-8 4017(1) pin 4 J5-9 4017(1) pin 2 J5-10 4017(1) pin 3 In addition to the SX28 connections on drawing 1, also add the following connections for the "left" wing. Connect the left wing connections to RC.0 to RC.6 (as similar to the right wing connections in Drawing 1) to RB.0 to RB.6 Connect the Reset for the New 4017 left wing circuits to RA.1. Connect the Clock for the New 4017 left wing circuits to RC.7. See the new attached code.
