RE: DC-3 scale landing gear plan
Great that you posted this coz i'm about to get my short kit with all fiberglass parts of Ziroli DC 3, i'm already looking to get it's robart retracts but seeing you did custom CAD based design as a set, plus it's at 1:7.5 scale, so i'm sure it will work perfectly and will look great for this model being 1:8 scale.....
Now when you say your compiled CD is for guys who want to make there own gears based on ur drawing, how much machining is involved to make the parts.
