Flight Log - 2011-05-21 - K Sonesen's Sardo XXL (Tube Fin)

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.

Flight Date: 2011-05-21
Rocket Name: Sardo XXL (Tube Fin)
Flyer's Name: K Sonesen
Motors: G80-7
Expected Altitude: 800.00 Feet
Wind Speed: 12.00 mph
Launch Site: TCC - Dairy Aire

The wind was blowing about 8-12 mph and the only launch rods available on this day were only 48" long so there was a bit of trepidation on my part.  Normally, I sim all of my rockets on a 6' rod.  The rocket jumped off the pad to about 30' and weathercocked into the wind.  Now tube fins are known for their ability to boost vertically in wind so seeing that, I decided against a second flight.

Note to self: Bring my 6' launch road to all launches just in case...
