Well, it at least you got to see it close up... It was still a really nice rocket - must have taken some time to put together...
Can I ask what method are you using for passing fire to the burst? Which fuel mix / delay comp have you finally settled on?

Tried a endburner with almost the same specs, only 15 mm ID.
I used 70:20:10 6hrs ballmilled, wetted and granulated BP, standard BBQ charcoal. The charcoal is not that bad, by the way, not for drivers.
One of them lifted VERY slow, and got stuck in a tree. A driver with a bit more fuel never got off the pole.
If you are going the "end burner way", use your fastest BP, and a smaller nozzle than you might expect.
Please do report how your experiments turn out, endburners are quite cool.

Pyromaniac303, you would be better off using 75/15/10 if your using bbq charcoal or possibly 80/13/7. When i make end burners i use meal 50% and green mix 50% then add about 3-5% 250 mesh Al (spherical) and they always perform very well. Also with end burners i use a choke of around 1/5th of the ID of the tube and use 3/4 inch ID tubes.
