I would like to believe that this document is correct, but unfortunately, material on hand begs to differ. I have in my possession one piece of PR G10 airframe and one piece of G12 airframe. ID's are the same, but OD of the G12 is slightly larger (my digital caliper stops at 6", so I can't give exact OD). I also have a G12 coupler and a G10 coupler with bulkheads. The bulkheads will not fit into the G12 coupler. So, although the chart says they are the same thickness, (at least on the 8" airframes), my on hand materials do not bear this out. Not tryin to start a fight, just sayin.......... Which also begs the question, what should I do with this rocket? The upper 48" is G12 and the lower 48" is G10. So there is a slight step down to the G10. The lazy builder in me will probably just sand the edge enough to make the difference less obvious. The super lazy builder in me will probably just build the thing as is; what step?
