RE: CG Eagle II Kit Build
I built the Eagle 2 about 5 years ago when the company was still owned by Goldberg. It went together easily and was a good first kit. The parts are not really self aligning - as I recall I used a small drafting triangle to set the ribs vertical to the building table while I applied CA. No problem really. The Eagle 2 is a good trainer and well worth building.
I recommend you carefully read the directions where it discussed the amount of dihedral to use. As I recall there were three choices.
