I bought a neat RV8 and I love it. The throttle cable is stiff and I know it's heat related. I want to order the correct cable so when I take that bad boy out I have one to put in. I'm having trouble measuring the cable in the plane. Anybody know the correct length for RV8 with IO360 A1B6 with Precision Air FI ? Should I use a string or coat hangar wire to measure it?
