Ggale, are you talking Super Stick? The Ultra Sticks come out nose heavy, but I think the Super's come out tail heavy.

Ken, have you checked the balance yet with the OS 50? I am thinking of putting the battery in the fuselage to avoid adding lead to the tail. (Saito 72 in mine, probably weighs the same as the OS 50)

I will beef up the landing gear area and maybe use nylon bolts there too, as some have done.
