# K Up Yonder

This is a custom, 54mm minimum diameter airframe, based on a KestreL kit from
[3 Dogs Rocketry](http://3dogsrocketry.com/).  The name is a play on "Way Up
Yonder" with the intended initial motor being the new 
[Cesaroni](http://pro38.com) Pro54 6xl K300 long-burn reload.

## Motivation

My fundamental objective with this airframe is to "need" the high altitude 
window at the NCR North launch site sometime in 2010.  This would have the
consequence of raising my personal altitude record from 14141 feet AGL on an
L730 in my Vertical Assault.  A secondary objective is to take one of our
[TeleMetrum](http://altusmetrum.org/TeleMetrum) altimeters higher than it has
ever gone before and demonstrate successful GPS based recovery with it.

I pondered various
airframe and other materials choices and designs over several months.  The
introduction of the Kestrel kit with an introductory special including the
Cesaroni Pro54 6xl case and associated tail cone rear closure was too good 
pass up.  However, as is often the case, I won't be building this kit stock!

The first flight is planned for [NCR](http://ncrocketry.org)'s Mile High
Mayhem 2010, weather permitting.

## Design Details

From the kit, we get:

* 54mm convolute fiberglass air frame
* 54mm Von Karman fiberglass nose cone
* 3/32" G10 fins
* Cesaroni Pro54 6xl case and tail cone rear closure
* G10 bulkheads and coupler stock

To which I'll add:

* [TeleMetrum](http://altusmetrum.org/TeleMetrum) avionics in the nose cone
* 5.6oz 2x2 twill carbon fiber and 6oz glass tip to tip on fin can
