  • Weight difference between Bob leaf tailwheel and stinger tailwheel

    Does anyone know the weight difference/savings between the standard Bob tailwheel with leafs and the stinger tailwheel. Also, what is involved to switch them out on a completed bearhawk?

    Somewhere here I posted the weights. If I recall correctly the weight difference is basically negligible.

    I switched from a leaf setup to a stinger. It’s not exactly a straight forward swap but it isn’t challenging either. Takes an adapter and a tail post insert.

      K thanks....just wondering if any benefit to switching it out for less tail weight. Hardly sounds like it.will try to find your post

        I haven’t found the post yet but will look again later. There isn’t a weight benefit but IMO the stinger setup of far superior.

          Hi Gary,

          Same weight on the two different Tailwheels. I’m not sure about leaf spring vs. round spring weight difference.

            I am not flying yet, but hypothetically the Stinger should be better than a leaf spring. A stinger is not directionally biased, it will bend as needed 360 degrees, a leaf spring is only up and down.

            The stinger should be easier on the fuselage in the event of a side load.

              One advantage of the stinger is that there may be less drag than a flat spring set up. Definitely a difference in the spring widths hanging out in the air.

                The stinger t/w weighs 6.8 lbs. The stinger weighs 3.2 lbs. Does not include the weight of the stinger to t/w attach hardware, (2) 1/4" bolts, (4) washers and (2) nuts.
