J-3 Cub

Well since starting my Spitfire/MJ100 project my father-in-law has been pondering and started to look at knocking himself up a little bush flier... So we've been chatting and he likes the Wag Aero-Sport which is a replica of a J-3 Cub. I know a little of the history of the cub, but I was wondering about performance, range, luggage capabilities etc, and what modifications are possible to it, popular conversions (extra bag tanks?), and what sort of gear he would need on-board for daytime VFR only.
I know Hagar will have a million and one useful bits of information on this one for me....
