Hi- I have a 1/6 Sig J-3 Cub that I converted to Super Cub. It isn't covered so I could send pics. I have all of the conversion parts hand drawn if you want them. All you would have to do is enlarge them on a copier to suit your needs. I even have a functioning door and latch mechanism. I made my own plug for the cowl. The wings are pretty much done. Some of the ribs are in different locations and the LE sheeting is different. I think the ailerons are the same as a regular Cubs (can't remember offhand). The Super has a wider basic fuselage so all of the turtle deck formers are changed. It has some stringers down the sides, too. The very early ones had gear same as Cub but later versions had different gear. Pretty color schemes for Super and mine will be red with cream. Paul Matt's drawing of the Super is what you need. Make plug-in wings with functional struts for the needed skylight area .Tailwinds, ARUP P.S.- look at my gallery- I build 'different' airplanes!
