Your plane looks tail heavy in that photo.
I basically balanced it so the tail would rise off the table. Which part of the plane should be completely level (ie perfectly parallel with the ground)? The CG machine came with a small bubble-type level device, but which part of the plane should it be placed? Near the tail? At the recommended CG point?
Which type radio are you using?

It's not computerized. Pretty basic.
