mabuse00 Posted December 14, 2014 Posted December 14, 2014 I always wanted to realise a GoGetter header, maybe I'll finally do it this year. I did some tests in the past, using the brilliant rubber/independence red nitrate only formulas suggested by Ned Gorski, using a small whistle tool with a spindle that resembles the suggested core dimensions. My experience: priming is a PITA, burn rate is insuficient for nozzleless. Maybe I pressed to hard.Some didn't even lifted of the ground. While these stars are otherwise hard to beat, bright and pure, I need something else here, and I'm lacking trial time. While remembering vaguely that I once found Kyle Kepleys Emerald Green/Ruby Red quite fast, and it's charcoal and sulphur content might ease ignition, maybe someone has another idea: Can you suggest a red/green formula that -burns very fast-lights with little prime-does not use Mg?
schroedinger Posted December 14, 2014 Posted December 14, 2014 (edited) For a white star, 5/3/2/1 KNO3/S/Al/Red Gum +5% Dex gives a star with enough power to be used for white gogetters. You can adjust the burn rate by choosing different sizes/types of al from -325 to flash grade. For coloring a god point to start of should be to add +4 pvc and + 10 coloring agent, lowering the sulfur by ten (based on 50/30/20/10). If you have fine mgal it should also turn up the burn rate a bit. Edited December 15, 2014 by schroedinger
dynomike1 Posted December 14, 2014 Posted December 14, 2014 Mabuse i had the same problem my green went up ok, red never left the ground.
nt8 Posted December 14, 2014 Posted December 14, 2014 (edited) I havent try with pyro magnal, but try with boiler anode magnalium (more Mg) Sr(NO3)2 53Anode MgAl 20Parlon 17KClO4 6redgum 4 I did nozzleless rocket with this comp.I didnt press, just bound with parlon in 12mm tube. Core: 5mm. Prime: KP/Magnal/C/redgum: 60/15/15/10Must be prime full core https://www.youtube.com/watch?v=HC7yMYKMYYY it would be try with fine pyro MgAL Edited December 14, 2014 by nt8
Jakenbake Posted December 15, 2014 Posted December 15, 2014 Maybe try using a smaller diameter and longer coring tool? I Haven't messed with green and red but tests of my perc blue are very impressive.
mabuse00 Posted December 15, 2014 Author Posted December 15, 2014 @nt8:nice one, well, that would be OK. Core: 5mmDiameter right? How long is it? No doubt KNO3 slowflash would work, but I want colour. green went up ok, red never left the groundI could only notice this in humid wether or improperly dryed stars - no wonder. Using little PVB and use isopropanol as solvent alleviates the problem.
