Ok... It's been a while since I posted one of these. Confession: When you're living in a foreign country (say... China), limited in your ability of the local language, and aren't living with friends, or attending school, the nights can be a little boring. Especially when it's -9C (15.8F), windy, and you don't have a TV, radio, or rocket to build. I contacted Mike Fisher of Binder Design and picked up a few details of the Excel to model in OR. Now full disclosure: This is based on the .rkt file of the Excel (single deploy) found on RocketReviews.com, so I can't vouch that the fins are a 100% accurate representation. The image was altered to turn the Excel decal upright. I may also have a reduced the size of the Binder Design Logo than it actually ships with. Before sharing this file, I asked Mike if this was Ok to share, and was told that I can. The kit is currently available from Binder Design for $129.99 USD as a 38mm powered version, and for $139.99 USD as the 54mm powered version. So, with that I present the Binder Design 4" Excel with Dual Deploy kit (54mm Motor Mount): PS Send Rockets!!! PPS Thanks Mike!!!
