Do you have one side hole in your stinger? if so, put another opposite. Try balancing your header like you balance a car wheel, the best you can. With the speed these things spin it doesn't take much to throw them out of balance.

single vent, I'll add another. I guess this will affect flight duration.

I have only ever seen 1g FE added, I'll try this new formula out when I feel a bit better (on antibiotics for ear infection). Love doing stingers with a decent flash header, once I get these babies working I'll post a vid or two. Feels like it's been weeks since I smelled the smoke - I hate being ill especially when you have to work while feeling like crap.

Out of interest, do any of you guys have some advice for getting these things balanced a bit better. Rockets are easy but stingers can kind of wobble while spinning up and can go off a bit sideways. I have tried sticking on an end disk with a hole for the pin. Sometimes that made it worse and they even seemed to have my name on them as they flew right in my direction.
I made a launch pin with slightly thicker diameter and that helps but I still see a bit of a wobble some times - or shouldn't I worry about it?

I let my rockets go in farmers fields around where I live. 3lb rockets ( 1" ID x 10" Long x 4mm Wall from www.charcoaldust.co.uk ) when these come down there is still some weight. Another thing I have been doing is making 3lb stingers with a big report. Flash breaks the casing up so I can let these go anywhere. I really would like to do whistle stingers now. I have Pot Perc with Sodium Benzoate, what formula would be best for it? Tried some pressed comp in a tube and no whistle - I want a really good scream...
