Strap-on Video Rocketry

One of my personal favorites… even if it makes the rocket a bit wobbly.

Here’s the video from the ground as the central I200 motor pops the rocket off the pad, and the on-board HCX computer ignites one of the two outboard boosters (I will light both next time by rerouting a wire so as not to melt it from the motor heat).

After parachute deployment on my rocket, three of nine Crayon chaser rockets blast off in hot pursuit. Next time, nine…

Holy Crayola!

Just saw a high-frame-rate video of this launch and the drag race with Erik (the 2nd and third video segments)

P.S. The strap-on is more easily seen at full size

P.S.S. The rocket’s perspective

great videos, Steve!

…boy, those motors really don’t burn very long, do they!?
why did the booster burn so smokey?

Sweet. Here is the video from the rocket

Jaako: I wanted to lay a "skunk trail" as I affectionately call it, a white center line with black on both sides. Next time I’ll get both boosters to light… The idea started with a desire for maximum contrast as seen from the ground and on-board videocam.

The motors have different propellant mixtures. Here is a big example of the blackjack motor plume:

Could you add a dupe shroud 180 degrees aound with a dummy mass to simulate another camera and eliminate wobble?
