# 2YikStik ## Motivation This is a "replacement" for Bdale's first L3 certification airframe, [YikStik](../YikStik), which was mostly lost. The name was suggested by Bdale's wife Karen to imply that it's in homage "to YikStik". The project sat as just a simulation file for a long time, until Ed Shibadeh from [Giant Leap](http://www.giantleaprocketry.com/) admitted at Airfest 16 that he had one last 98-75mm Slimline Tail Cone in his personal collection that he would be willing to let Bdale have. It's silly how much the little things matter sometimes! The tailcone wasn't even part of the early YikStik design, but once it was added it somehow became an important element of the overall design that Bdale wasn't willing to do without on this project... Meanwhile, Robert became interested in measuring the temperature of a nose cone and a fin on a rocket at speeds above Mach. This led Bdale to design a [TeleMetrum](http://altusmetrum.org/TeleMetrum) companion board called [TeleScience](http://altusmetrum.org/TeleScience) capable of hosting up to 12 NTC thermistors for temperature data collection. The plan is to fly two TeleMetrum+TeleScience setups, one mounted in the nose cone and one mounted in the fin can. The one in the fin can will be responsible for apogee deployment, and the one in the nose cone will handle main deployment. Jeff Lane of [Shock Wave Rocketry](http://hockwaverocketry.com/) expressed a willingness to fabricate a custom 98mm nose cone with the temperature sensors embedded in the glass layers, as he is also interested in the data we hope to collect. ## Design Details * 98mm [Giant Leap](http://giantleaprocketry.com) Dynawind air frame * 75mm [PML](http://www.publimissiles.com) phenolic motor mount * [Shock Wave Rocketry](http://shockwaverocketry.com/) fiberglass 98mm Von Karman 6:1 nose cone * custom fins, using 1/8 inch birch plywood laminated with carbon fiber and a fibreglass sanding veil * 3/8 inch birch plywood centering rings and bulkheads, CNC milled, the two that hold the fins are double thickness (3/4 inch) and notched for perfect fin alignment. The OpenRocket design file is 2YikStik-2TM.ork in Bdale's git repository. ## Build Parts gathered during October 2010. ## Publicity ## Flights The objective is to fly 2YikStik at NCR's Mile High Mayhem 2011 on a [Cesaroni](http://pro38.com) Pro75 6xl Green3 reload. If that goes well, we hope to be able to fly a Pro75 6xl Imax load at LDRS 30, perhaps as a research load.. Stay tuned!
