Panel Holes For Throttle/Mixture/Prop Control Cables
If you are talking about hole sizes in the panel for the throttle, mixture and prop controls, I just completed this in the past few days on my RV-7 QB.
I am using the stock Van’s supplied control cables in the RV-7 IO-360-A1B6 angle valve finishing kit. I don’t know about others.
Throttle, ACS A-800BL0505-V, Panel nut thread ½ x 20, Panel hole is .500”
Mixture and Propeller, both ACS A-1760 series, Panel nut thread is ¾ x 16, Panel hole is .750”
