A finless rocket that flies stable?  That be t' mission o' this rocket.

This rocket is a scratch build / scratch design that uses Gas Dynamic Stability (GDS) and Spin Stability.

An Ikaros Marine Flair uses GDS t' stabilize t' rocket launched flare.  It has openings below t' motor nozzle and t' motor exhaust sucks air into these openings.  That stabilizes t' rocket as long as t' motor is burning.

T' problem with that concept for a model rocket be t' motor only thrusts for a short period, me bucko, after that it coasts.  You loose t' GDS durin' t' coast phase.

Spin Tabs, aka canted fins, me hearties, are used on this rocket.  This gets t' rocket spinnin' about its longitudinal axis, which stabilizes t' rocket durin' t' coast phase.

This rocket also features a custom wood lathe turned nose cone, me hearties, made from pine.

Powered by a 24mm motor, recovery is via a 12" nylon chute.

A 2" PVC pipe is used as a launch silo.
