idp06,

It will depend a little bit on which kit you are dealing with, but this is what I flew:

+ CG ... 4" behind leading edge.
+ Aileron ... 3/4" up and down.
+ Elevator ... 1" up and down.
+ Rudder ... 1-1/2" side to side (or as much as possible without touching the elevator).

Adjust to fit your style once you get through flight testing.

Have fun!

For what it's worth, I built two cubs, the GP .40 and the CG .40. As I recall, both balanced on the main spar.
