Bio Jetpacks

[calabim]

I know this has been suggested in previous threads. As I recall, deathspitters were used as jetpacks.

Anyone considered the use of spinefists? Having the arm sticking out, and the spinefist itself pointing towards the tail. Paint it with flames.

Any thoughts on this? Anyone else considered it?

Hmmmm.....Bio jetpack eh?
Here is my version. Hope it helps!

Just something I threw together!

You should either add some bulbous combustion chamber organs to this, or a large air intake toward the top for atmosphere to be drawn in, compressed and jetted out the bottom nozzles.

A two part fuel like hydrazene and hydrogen peroxide wouldn't necessitate intakes but would have multiple feeds to the nozzles. There are biological two part explosives, like that of the bombardier beetle, which could theoretically be used by a Tyranid for rocket propulsion with a sufficiently hard chitin combustion chamber, and exhaust port.

i would like to use spinefists to make jet paxks for cost effective gargoyles.
I wouldn't have flames coming out the back though.

It's already been done by Mr. Pink at warpshadow.com!

That's a really cool conversion, but what did he use for that middle piece? I can tell most of that, but that one.

It looks like the underside of a devourer.
