+# Trick-o-Treat
+
+This design is a loose upscale of the LOC Lil Nuke, in 98mm Dyna-Wind airframe
+with 54mm motor mount.  It's a great all-round sport rocket, perfect for drag
+races!
+
+## Motivation
+
+Keith and Bdale wanted to drag-race airframes using 
+[TeleMetrum v0.1](http://altusmetrum.org/TeleMetrum)
+altimeters with GPS modules at NCR Oktoberfest 2009.  Unfortunately, they
+didn't have suitable matching airframes.  Bdale quickly designed this rocket
+to be something they both would build, and delivered a semi-kit of parts 
+including plywood fins and CNC-cut centering rings to Keith just in time
+for two rockets to be ready to race!
+
+## Design Details
+
+* 98mm [Giant Leap](http://giantleaprocketry.com) Dyna-Wind air frame
+* 54mm phenolic motor mount
+* [Public Missiles](hattp://publicmissiles.com) 54mm HAMR motor retainer
+* MadCow Rocketry [98mm nose cone](http://www.madcowrocketry.com/servlet/Detail?no=74), though we debated using the [Giant Leap](http://giantleaprocketry.com/) Pinnacle 98mm nose cone, which would also be a good choice
+* 1/4 inch glassed birch plywood fins in a custom shape, with beveled edges
+* 3/8 inch birch plywood centering rings and bulkheads, CNC milled, the two 
+  that hold the fins are notched for perfect fin alignment.
+* avionics bay built as a "slug" that slides into a single piece of airframe 
+  tubing containing both apogee and main deployment bays
+
+## Build
+
+Construction occurred during September 2009.
+
+## Publicity
+
+Trick-o-Treat is featured on the 999J600 Red Lightning page of the 
+[Cesaroni Pro38 catalog](http://www.pro38.com/pdfs/Pro38Catalog.pdf)
+
+## Flights
+
+First flown at NCR's Oktoberfest 2009, in a drag race with Keith's nearly
+identical airframe "Candy Cane" on Cesaroni Pro38 6XL 999J600 Red Lightning 
+motors.  Trick-o-Treat got off the rail first, Candy Cane got slightly more
+altitude...  Due to a wiring error, Trick-o-Treat deployed the main at 
+apogee leaving Bdale with a longish walk, while Candy Cane flew perfectly!
+
+Flown several times since at Hudson Ranch and elsewhere as a test mule for
+[TeleMetrum](http://altusmetrum.org/TeleMetrum) development.
