In summary, I would say that the Eradicator was a straightforward build, with enough challenges to make it interesting (i.e. fin slot cutting, ring fin painting, impressive decals), but with parts that went together quickly and accurately. The fit and finish on the kit were (like every other Sirius kit I've built) top-notch. It's an eye-catching bird, and I can't wait to put her up this summer, first on an F50-6T, then later on a G40 or G64. There's plenty of room in the upper tube for dog barf, the 30" chute, and my Altimeter 2 & squealer, so I expect a great set of flights. I'll be sure to stop back and post pics of her boosts.
If I had not been taking my time to document the build with photos (not to mention wanting to double- and triple-check my work, since I knew I'd be writing a review), I believe I could have built the Eradicator over a weekend or two. As it was, I spent about 24 hours total on it, and the results, I believe, speak for themselves.
Looking forward to the next rocket to emerge from Sirius Rocketry's shipyards, David. Hope it's soon!
