Anyone seen my latest article at:

The article explains how to trick RockSim version 8 to take into accout the dynamic base drag effects which are important for short wide rockets.

What do you think?

I tried the technique to model a few saucers. It appears to place the CP too far aft.

I have tried varying the length of the cone, but Rocksim 8 is behaving weirdly when I try to vary the cone size.

The article says this works for cones too? If so that will make all the difference to a design I've been toying with for a while. I think some sub-scale test vehicles are in order!

I liked the article! Keeps one from having to search threads on TRF to find your explanation
