These are some of my favorite videos posted by Contrail long ago; They are of the test sessions performed by Tripoli and Contrail. In most cases I liked them for the long burn characteristics... but then there is just something about those sweet looking sparkies too...

So what is funny to note, is how many times the testers jumped when the motor came up, and how hard they tried to muffle the noise with the palm of their hands... why no ear muffs, like is required at a gun range...(?) Too Funny!
