I did a little testing with the GB-6, and found that, if I'm climbing at 35 degrees and 500 knots, if I release the bomb at 8,000 ft AGL, I can loft it to about 13,000 ft and get a range of about 24 miles. I started a spreadsheet to track other tests, but damn...it's hard to control all of those factors to test all practical possibilities, so I thought I'd toss (no pun intended) it out here. What lofting parameters have you all found for your GB-6s?
