    Hey guys,

    I'm about to order the fairleads for my fuselage. I'm a bit confused about the sizing. I've got 3/4" inner diameter of the failead tube, nothing special here. The length of the tube pieces is 3/4" as well, but which tube do I need from ACS?

    3/4 * 1" or 3/4 * 3/4" ? Which length is the correct one? Unfortunately there is no drawing, so I don't know whether the lenght given is the actual length of the fairlead or the lenght of the tube in which is is installed...

    Thank you for chiming in!

    The S-1S uses 7/8" x .049 x 3/4"(long) tubes for the fairleads.

    That's exactly what I used, but now I'm looking for the corresponding fairlead.

    Do I need the 1" oder 3/4" long fairleads? Is the given lenght the lenght of the fairlead itself or the length of tube it is made for?

    You will need the 3/4" x 1" fairlead. They are designed for 3/4" long bushing tubes. The shorter ones are designed for 1/2" long bushing tubes.

    Everyone is so concerned about weight, I'm surprised you all don't use the 1/2 long ones. A whopping 33% weight savings.

    that's why we strive to build our airplanes so light, so we can go out and order the fattest steak on the menu.




    and cake...........
