Hi Bryris
I built the Carl Goldberg Super Chipmunk approx 10-12 years ago when the parts where cut out with a die. I am currently building another CG Chipmunk and this kit is lazer cut. Lainer now own's Carl Goldberg's kit production and the instructions and plans I have with my current kit look like bad copies of the kit I purchased long ago. Save your money and use what you have!
