Question
Horizontal position of wing on fuselage

Hi Everyone!

While in the process of making stick rc planes with foam wings, rudder, elevator, etc... I ran up with a question on wing position.

Assume the fuselage (ie. stick) is 27". I made an RET plane with the following characteristics:
Wing chord: 5"
Leading edge of wing: 9" in back on fuselage.
CoG: 10" back on fuselage.

I chose the wing's leading edge to be 9" back (which is 1/3 of the fuse length) - that seems to be about where most trainer planes have their wing location.

The plane flew just ok since - I had some issue with the control surfaces and since I'm almost a newbie.

Is there a "suggest" horizontal location of the wing on the fuselage??? Would the same plane be able to fly if I put the wing's leading edge closer to the front (off-course the CoG would change:

Wing chord: 5"
Leading edge of wing: 2" back on fuselage.
CoG: 4" back on fuselage.

Also does the CoG have to be located somewhere on the wing?

Thanks.
