I spotted some inconsistencies between the posted RockSim plan and the version I'm actually building. They are minor, and probably won't affect the performance of any model built from the first version. I just wanted to be accurate (as far as it's possible with RS...) with the presentation.

There isn't enough of an appearance change to notice, just a slight repositioning of the fins.

Here's what really changed: The rear tube is 3.5" long, not 4". The core tube has an exposed length of 3.5" instead of 3". It is still 8" long. The rear fins are located 0.25" from the rear edge of the tube, and the forward fins and dowels are adjusted to fit.
