I installed both throttle controls in the plane today. I installed the brackets I had made and drilled out the panel. On the passanger side I removed the friction lock that is inside the cable. I did this so that it could never in advertently jamb or tighten on me. I modified the stock throttle cable from Aircraft Spruce and cut to the correct length. Installed the custom brackets and attached the cables to the bellcrank. I needed to squeeze the ends of the bellcranks so that they were flat and I could drill for the cable connectors. I pulled the cable tigh fromn the panel to the bellcrank and secured the cable clamp.
Pilot side throttle control. I will have a custom know made.
