This is the "well, crap, that ain't supposed to happen" edition. I proceeded to dry stack the parts, put in a motor, and fill the nose section with 0.8 ounces of lead. I checked the CG and it is almost as specified in the instructions. It is less than 1/8" of the goal. Well, that's not too bad.Then I raise one eyebrow as I look at those tiny fins. True scale, bo clear stuff.Then I weigh it and find it comes in at 4.21 oz. I check the charts and Estes launch weight specs and find this doesn't leave the proper thrust-to-weight ratio and exceeds Estes' recommendation. hence, the "well crap" status.What's an extra 0.21 ounces anyway? Where are my B14s?
