This is a Larry Brand design that can be found here on EMRR Rocket Reviews if you search on "Larry Brand" or "Sardo XXL".

This rocket has a 38mm motor mount and is constructed using mostly LOC parts although I did use simple postal mailing tubes for the airframe and tube fins.  The tube fins are laminated with an inner half-doubler made from postal tube.  All up weight (recovery, links, nomex blanket, 36" Topflight chute but NO MOTOR) is approximately 35 oz.

Larry Brand describes this rocket as an upscale of his Auracle 54 design which I have also built and named "Steppin' Razor".  Therefore, this one is named "Steppin' Razor II".

I made my level 1 certification flight with this bird. Successfully, too.

This rocket has been updated to dual deploy in 2015.
