dan999ification Posted April 21, 2013 Posted April 21, 2013 Hi all, i had to share this one even though the timing was off a bit. http://youtu.be/yJhmcBji5oQ It's a 10mm endburner with a 40mm rondelle to bs shell that ended too quickly, spread over two seconds would give a better effect. Questions and comments welcomeBuild vids if needed. Dan.
Mumbles Posted April 22, 2013 Posted April 22, 2013 Looked pretty good. It appeared to be more of a ring of salutes instead of a rondelle though.
dan999ification Posted April 22, 2013 Author Posted April 22, 2013 (edited) Cheers guys, I'm thinking of going bigger on a one pound nzless. I didn't want these coming down as the little endburner I put it on only gets this high with a heavy ish header so I went for short delay between break and reports.When I lined the fuses up they were shorter at one end of the row but obviously not enough difference between them. Be better if there wasOne or two Seconds from first to last report.http://youtu.be/KLFCERtVa-IYou should be able to see the tubes are numbered.http://youtu.be/C2xmSqt5NEYWeigh in.http://youtu.be/0fjDO8-e4YI Overall I'm quite pleased for a first attempt, keeping the weight down interfered with the results though. Sorry for the multiple files I can't edit YouTube with my phone yet. Dan. Edited April 22, 2013 by dan999ification
LTUPyro Posted April 22, 2013 Posted April 22, 2013 Bs was little to fast. But anyways, shell looked amazing!. Love mini multi breaks.
Bobosan Posted April 22, 2013 Posted April 22, 2013 Good job! 10mm (2oz)? That's the size I've been experimenting with and having fun.
BlastFromThePast Posted April 22, 2013 Posted April 22, 2013 What height do you think you got on that? It looked low to me but maybe it was just the angle...
dan999ification Posted April 23, 2013 Author Posted April 23, 2013 50-60ft perfect for this size. They go higher with more bp in the motor, this had 4.5g at least halfA gram is wasted as the grain burns out.A small report can be carried high by these with 6g bp but I have over lifted small shells and can't see the effects. 4.5g bp lifting 75g more efficient than a mortar Dan.
BlastFromThePast Posted April 24, 2013 Posted April 24, 2013 I'm sorry for the stupid question but whenever I see "bs" I think of my initials . What is bs referring to again?
dan999ification Posted April 24, 2013 Author Posted April 24, 2013 (edited) I think of something else when I see bs In this case it means bottom shot. Dan. Edited April 24, 2013 by dan999ification
BlastFromThePast Posted April 24, 2013 Posted April 24, 2013 Thanks for the clarification and yes. many do think of something else, but I find it humorous to have those initials.
mabuse00 Posted April 25, 2013 Posted April 25, 2013 Very nice one, thank you for the video. I love that caliber too, 10mm is great for small experiments. 4.5g bp lifting 75g more efficient than a mortar 75g sounds very much for an endburner. I did whistle motors (36mm spindle!) of that size that did 75g and I think they will do 100g, but that can't be compared... What was the takeoff-weight that specific rocket?
dan999ification Posted April 25, 2013 Author Posted April 25, 2013 Thanks, yes it is a good size for experiments to be honest my only truly dialled in motors. The header is 28.8g on the scales (above) I didn't weigh the finished rocket because they normally are 70-75g, with headers under 30g and a 1 ounce stick. I have lifted more total weight with these but 75g is about the limit to be safe. Dan.
