Texas Firefly

SEMROC Model #KA-8


The Semroc Texas Firefly is a beautiful 175% upscale of the Semroc Firefly and is a Retro-Repro clone of the original Centuri Firefly 2-stage rocket. Combining elegance with a beautiful simplicity of line, the Texas Firefly flies wonderfully on standard 18mm black powder motors with a unique gap-staging design to enable reliable upper stage motor ignition.
