Great Gizmo Race
sponsored by Wildman Rocketry at LDRS27 in Argonia, Kansas.
It’s a rare treat to see them all roar off the pad at the same time, and then spiral around like Keystone Cops. The sparky green one went into a death spiral and crashed into the farm dirt near me. (Since these are all the same rocket kit, I suspect the difference in flight dynamics derive from differences in nose cone weight.)
This is one bank of rockets; there was a second bank off to the left launched at the same time.
