firebird Posted September 18, 2010 Posted September 18, 2010 Here is my latest 6# whistle rocket with a 10 inch header Shell was my Fire Fly and weighted about 14# It could have used a bit more delay and I should have added some tail. I will be tossing up a 12 on a similar motor real soon . I have it built but have been working nights with little time to test
Gunzway Posted September 18, 2010 Posted September 18, 2010 That was a beauty! That would have been really impressive to see in person. Good work, and I'm looking forward to seeing that 12" on one of those motors. How far back were the audience?

I was about 100 ft away when it went up, it was loud. I am working on a bigger motor but I have a bit of work to do I am going to make the press remote operated for these bigger boys. I will have to set up for each increment then retire 75-100 back and press. When these things CATO it's ugly.

firebird Posted September 18, 2010 Author Posted September 18, 2010 (edited) Have you had one CATO in a press yet?No Never had a problem it is more of a safety precaution. These are pressed out doors and I don't ever anticipate a problem but I would rather not find out the hard way. I have 3 inch tooling being made that will have a 18 inch core. I have video of one of my 3 inch whistle motors blowing and the fire ball was about 70 ft wide. That one only had a 6 inch core. There is alot of fuel in these motors. We are going to be doing some destructive testing soon. I am waiting on a clam shell and a few more spindles that are being donated. these will be blown in the press and we will be tapeing. also setting up sheets to show where the blast damage was the worst. I will post when it happens Edited September 18, 2010 by firebird

firebird Posted September 18, 2010 Author Posted September 18, 2010 NEPT on the 6# and down sizesThe 6# hot motors have to be reinforced.
dagabu Posted September 18, 2010 Posted September 18, 2010 Damn fine looking rocket and header! I am not anywhere close to making those monsters but I can agree that you need to have some distance from the press Welcome to APC, teach us big rockets please!!
OneEyeCharlie Posted September 18, 2010 Posted September 18, 2010 Struck by a serious case of rocket envy
dagabu Posted September 18, 2010 Posted September 18, 2010 OEC, Its not the size on a mans rocket that matters... Oh who am I kidding, I'm jealous too!
