CG data - Ok guys I got the CG dead nutz today. For totally neutral it is 3.25" or 82.55mm from the leading edge of the wing where it meets the fuselage.
If you like 3D only and prefer to harrier and hover all day then you may move back slightly from there. If you like all precision and rolling you might move slightly forward from there.
*Battery location in pic is with the gear.

This thin has a fast roll rate. So if you are uncomfortable with that you may want a dual rate on Ails.
You should be able to get very close to the stops both up and down but not hitting them.
Rudder, I get about 130% endpoints. You do not need all the throw it can give. You will probably want to tame it down to +- 30ish degrees of throw.
The differential control arm that comes in the kit does a great job of making even Ail throw up and down.
Let your baby dry for a bit before you fly it. If you are like me most of it is still half dry!
OMG is she H O T!
After you are happy with the battery location. Put some Welders in the hole and seal up all the foam in the battery hole. That will keep it from tearing with repeated use.
I used most of one tube of Welders to finish this plane. I go the box from USPS at 1pm and I was hovering it in my workshop by 6pm! And, that is with taking photos at every step!
