pyrothrust Posted December 3, 2011 Share Posted December 3, 2011 How much more powerful is copper oxychloride than Iron oxide? and as a catalyst Which is the best to use for power rather than noise ,the Iron oxide, Copper Oxychloride or Sodium Salicylate also I have been using 70 /30 Potasium Benzoate is their a better opitmal ration. regards Link to comment Share on other sites More sharing options...
Mumbles Posted December 3, 2011 Share Posted December 3, 2011 Typically the people who know what they're talking about with regard to rockets (IE not me), will prefer copper oxychloride over iron oxide for power. About the only real data I know of on the matter comes from Danny Creagan. http://www.wichitabuggywhip.com/fireworks/rockets/whistletests.html Link to comment Share on other sites More sharing options...
firebird Posted December 4, 2011 Share Posted December 4, 2011 Sally is great for speed Benny is good for power IMO I prefer Cu Oxy for power and IO for sound but there is alot to be said about spindle design if sound is what you want Link to comment Share on other sites More sharing options...
firebird Posted December 4, 2011 Share Posted December 4, 2011 I prefer a 76/23/1/3 mix my self but I have never ran any of the older red gum formulas Link to comment Share on other sites More sharing options...
Juiceh Posted January 4, 2012 Share Posted January 4, 2012 (edited) 76 / 23 / .5 / 2.5 Perc / NaSally / Copper Oxychloride / Vaseline This is my favorite blend so far. Half a percent of copper oxychloride is all that is needed. I mill the catalyst into the perc in a tweaked 6lb harbor freight tumbler for 6 hours with ceramic media, probably a bit overkill on the time but the mix flows great and there is no question that the catalyst is well integrated. Lacquer thinner is the solvent for the Vaseline. This fuel has tons of power. I like to use it for strobe rockets, since it has more power than the Iron oxide mix you can cut back some on the beginning whistle increments and use more strobe fuel for the core. This fuel can't be used for everything though. It's best used in moderation, or you get CATOs. Edited January 4, 2012 by Juiceh Link to comment Share on other sites More sharing options...
FREAKYDUTCHMEN Posted January 5, 2012 Share Posted January 5, 2012 Nowadays I'm only using potassium benzoate as fuel, this fine and non hygroscopic fuel has lots and lots of potential, with CuOCl or FeO, the difference is not really that big, both catalysts preform really great.IMO the fuel is most important factor for sound and powder. No moisture in it and fine powder. Link to comment Share on other sites More sharing options...
