Just in case note: Unless you are familiar with the way Cubs fly, you may not like what you get. A Cub requires deft use of the rudder. Banging the ailerons around makes a Cub look very sloppy. It should fly very slow. A full-size J-3 Cub is hard pressed to break 75 or so mph. If you want an aerobatic model and still want a Cub, you'll do better with a clipped-wing version. If you want a really aerobatic plane, look elsewhere.

Goldberg had a Cub kit that got high marks from a lot of people. I think the SIG 1/5th scale is laser cut and more sheet/former/stringer than the old kits. It should be pretty straightforward to build.

But a Cub, with the struts, cloth covering, complicated landing gear, big windows, engine detail, and large cockpit can't be a simple build and still look like a Cub.
