Mini sounding rocket + EVA extender

[spiritplumber]

A self-decoupling small solid rocket, can be used as a missile / sounding rocket. If carried on EVA using KAS, it can be used to extend the EVA tank. Uses existing models and textures to save memory.

Have you actually tried these? This will add a duplicate RESOURCE_DEFINITION, and it looks like the bottom stacknode will be nowhere near the bottom of the part (same with top, but less so--looks like it's twice as far up as it should be)

That said, always nice to see new toys!

Fun idea! If modulemanager is able to modify an existing resource definition, that would be another way.

His changes have the density of monopropellant, the original EVA fuel has zero density and other unsuitable settings for this purpose.

I have tried it, and it does work. I agree on the bottom node - it doesn't seem to work anyway, this is intended to be connected radially.

Could you post a screenshot? Thanks!
