  • 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.

              We used to think that too. Experience is showing they are perhaps equal, or perhaps the stinger is actually less able to protect the fuselage from side loads.

            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.
