Estes Bandit Motor Failure



These are the last photos to show the only Estes Bandit I ever owned while it was still in pristine condition. They were taken in northeast Switzerland on April 16, 1986, during the same launch that saw an Estes D12-5 motor failure destroy my Centuri Nike Smoke.

When building the Bandit, I had converted it to fly on 24 mm motors, and this would turn out to be its ruin. The top photo shows pre-launch preparations; this flight was also going to use an Estes D12-5 motor, which can be seen already installed, with the Estes Solar Ignitor in place. Also of note are the Flight Systems Inc. E and F black powder motors in the range box.

The lower photo shows the Bandit on my converted theodolite metal tripod launcher, shortly before the launch button was pressed. Upon ignition, the motor disintegrated before the rocket lifted off. A single, burning motor fragment was ejected from the resulting fireball. The rocket suffered significant internal damage, but the main airframe was surprisingly still somewhat intact.

This was the second Estes D12-5 motor failure that day, and another one (a D11-9) was still to come. The damage to the Bandit was rather disappointing; its beautifully nostalgic design was among Estes' most attractive at the time, and its internal baffle system made it an intricate and unusual model.
