    Default Pitot tube gauge/size for sport cub #004

    Hey ALL,

    Doing some research for upgrades. Does anyone know what gauge ram air tubing for the pitot system was used in the early sport cub? I am not back at my hanger for a week to check myself.

    Thanks in advance and happy trails.

    That sounds way too large. Are you talking about the aluminum tubing in the left forward jury strut? Should be more like 1/4 OD with 1/4 ID plastic line in the wing.

    I figured he was/is referring to something like the Dynon Heated Pitot. or the G3X option

    Yeah 1/4 in the cockpit, my bad. #fractions. I had called someone in parts/ service at cubcrafters. They had told me it was 3/16 outside Diameter for the sport cub #4. While I appreciate the response from the department, I ordered the wrong size tubing and tees to split off for the G5. It was 1/4" like Pete just said.

    I accidentally broke my pitot tube off while washing on CC-11 #16. I just ordered a new jury strut and pitot tube assembly. Super easy to change out. I did have a difficult time communicating the style of pitot tube the early birds have on them. Stan knew exactly what I needed, but (good for him) he has retired.
