Title: Drawing control system routing
Control yoke has been located in forward fuselage along with rudder pedals. Now it is time to plan routing of aileron and rudder cables as well as the pushrod that will control the horizontal stabilator. Aileron: I have modified the routing due to the use of my control yoke mounted near the firewall forward of the Landing Gear Main (LGM) box. There are two pulleys mounted at the base of the yoke, directing the control wires forward to the base of the forward side of the LGM. Two pulleys there send the wires through the LGM to the aft side, where two more pulleys direct the wires out to the sides of the C-channel. Two additional pulleys direct the wires aft, to the corner posts, at the base of which will be a bellcrank directing the forces upward via a pair of control rods to the Aileron belcrank. A connecting wire will continue aft from the lower bellcrank, turn inward by a final pulley to close the loop. A turnbuckle will be placed between the 2 aft pulleys to adjust tension. For the rudder control, the cable will attach to control arms on each rudder pedal assembly. These are outside the control yoke base, approximately 6 inches apart. They will be routed to the base of the forward side of the LGM and using pulleys will be sent to the rear of the LGM. Pulleys there will direct them toward the center approximately 2 inches apart. The cables will continue rearward and to another set of pulleys that will direct them upward along the bottom of the empanage to the Rudder Bellcrank. Here they will control the rudder as well as the tail wheel. Horizontal Stabilator: This is manipulated by a control rod from the mid point on the control yoke shaft. The shaft is angled downward to run along the top of the LGM and aft toward a bellcrank within the center tunnel between the passenger seats. From the bellcrank, another control rod will connect to the Horizontal stabilator bellcrank at the rear of the fuselage. Preliminary measurements and locating the pulleys will be done prior to making the bellcrank and pulley brackets. The bellcranks are weldments that will be produced later.
