T-max,

You can actually go into the Super Cub thread and ask there about the J3 Cub, Because a lot of the guys there have multiple planes and i'm pretty sure a few of them my have that plane you are asking about. Another thing you could do, is when you creat a thread put the name of the Plane in the title. I have found that I have gotten more relpies that way about whatever R/C I'm asking about.
