NACA 66 Special A/BGS

That will give us 3.33 to 1 but we might just run gears like they are. It's a bit of a pita to change gears in this car and I don't want to make too much torque to rear wheels as I do not want to spin and ruin a set of tires. We can go 220+ in first gear. Goal is to test chute deployment, not go fast.
There is one easy modification we can make to make it easier to change QC gears but it will have to wait until we have wings off.

Rob, good move on your part, you have a lot of time now and sometimes baby steps will teach you and the team a bunch, take videos front and back on the test runs, you don't want lift or spinning chutes. Good luck wish I was there to watch/help.

We are in reassembly/button up mode. Gears are switched, tires installed. Fuselage next, then load everything up for a 4am departure. If we don't run into any trouble we will be in Wilmington bright and early!

FANTASTIC NEWS! 
I think I can speak for all here in Wilmington that we can't wait to drool over it and see it run down the track!
Also, I look forward to meeting all you guys.

Rob, I think you have made a wise choice in the location of your first tests.

You will have support from the track management that will surprise you.

Congratulations on your testing concepts.

The best to you and your team.

I just posted this in the Wilmington Picture Post thread:

Pictures do not do justice for this car. It's an absolutely incredible work of art.

Here are the links to the videos that we took from on the Carbiliner this weekend.

The first video is pass #1 at 141 MPH out the rear to monitor the chute performance. We've watched this video 100 times, there is a wealth of information about what is happening with the car aside from the chute data we were looking for.

http://youtu.be/M7YdpE_DiKo

Pass number two with the camera mounted on the left side wing looking forward. The location of the camera was almost directly above the axle. The microphone clearly picked up the interaction of the gears within the rear-end!
