If I may suggest the Sig 1/4 scale Cub is a great scale Subject,
The build is very involved but you have plenty of plane to work with for sale details and it can handle a little extra added weight from the details without any issues.
The Sig 1/5 scale makes a fine looking plane and is a more modern design that is more builder friendly. Both kits will produce and excellent looking and more importantly great flying plane.
