Thanks for info. I have a good memory it is just not very long and 25 plus years ago is a long time. The ones I built were in the 40 size and as best I can remember now wing span in the 40-50 inch range. They also made a 60 size with a larger wing span, probably the 60 inch. Mine were trike geared and shoulder winged. At the time I lived in Colorado so during winter I would take the wheels off and put skis on to fly off the snow rather then shovel the runways. The state park provided a flying site with paved runways and pit areas, however my club had to do the maintenance on the field, like shovel the snow.
