# 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.
