    Paul, are there excellent SolidWorks files available such as a
    tractor driven unit 13B that I could adapt to a super cub/Patrol
    frame?.  We have solidworks, and if there are some time saving work
    already done, I would provide feed back when a new or different mount
    would be drawn up.

    The drawings/modeling of the 20B for the pusher were good and made me
    think there was others already out there.

    Scott

    Sure Scott. The files are too big to email so I will set up a download
    area on the web site with a stp file.

    RV4's are about the right width so one of these might work.

    I'll take the RV4 landing gear tubes out.
    Give me a day or so.

OK it is not as big as I thought so here is a stp file zipped
that will load into Solid Works.
