David's Level 3 Certification Attempt Page

Introduction

I purchased a 11.5 inch nose cone from another Syracuse Rocket Club member. The plan was to someday use it for my L3 rocket. Someday has arrived.

The Plan

The plan is to fly my L3 in 2009.

The Rocket - Grounds for Divorce

The rocket is going to be around 11.5 foot tall, and be 11.5 inch diameter rocket with four fins named Grounds for Divorce.

Parts

I've ordered a bunch of stuff from Red Arrow Hobbies:

two 48 inch tubes
one 11.5 inch coupler pack (coupler, one bulkhead, and u-bolt)
three centering rings for 98mm motor tube in 11.5 inch tube
one 36 inch 98mm motor tube
one 36 inch 75mm motor tube
three centering rings for a 75mm motor tube in a 3.9 inch tube
one bulkhead for 98mm motor tube (which is too small by about 1/8 of an inch)

More stuff purchased at Pittsford Lumber:

West Systems Epoxy
Three 20x48 half inch birch plywood sheets (for the fins and electronic bay bulkheads)

Rail buttons purchased from John DeMar

Missile Works RRC2-mini Altimeter and PerfectFlite Altimeter.

Still need to get/decide on:

Am I going to use a deployment bag?
Parachute. As I see it, I have two choices:
- Buy a "real" parachute, like the SkyAngle's Cert-3 XXLarge, http://www.b2rocketry.com/. Nice thing about doing this is they also sell a matching deployment bag. Bad thing is the price ... almost $240.
- Buy a playchute and sew lines onto it, http://www.amazon.com/20-Parachute-with-16-handles/dp/B0007PC92A/ref=pd_sxp_grid_pt_1_0. Nice thing about doing this is it would be much cheaper ... $80. Bad thing is I'd have to sew the lines on, and I'm not sure how well it would fit into a deployment bag.

BFR Registration Form

The original plan was to fly this rocket at NYPOWER 13. The BFR committee wants to see some basic information about the rocket and planned flight. This is my posting to the NYPOWER BFR forum. It will be updated as things get decided.
