We are going above 100,000' with our DoubleSShot but it will not be at BALLS since we use a steel nozzle (not permitted buy Tripoli). I was hoping we could be ready for the days between XPRS and BALLS but that isn't going to happen.I was building a two stage sugar with graphite nozzles for the competition but with the SugarShot being the priority, looks like I will not be ready with it for 100,000' at BALLS. Here is something that Bryan Dierking and other students might be interested in:http://www.dataq.com/science-fair/science-fair-projects.html Rick From: MonsieurBoo@xxxxxxx Date: Wed, 3 Aug 2011 13:08:31 -0400 (EDT) Subject: [roc-chat] Re: Discovery at LDRS Hey Richard, Since you mentioned altitude contests, you might want to consider BALLS in September. Carmack (and a few others) have put up a prize for a flight >100K ft and it looks like at least a couple of competitors are going to try for it there. (Rick Maschek plans to be one.) Should be a kick. Cheers, Mark L.
