They'd never allow it in the tunnel for safety reasons.
It will have to be designed into the build with the facility for robust attachment.And I have no way to cut off the tail with any degree of accuracy at this sort of scale.
Perhaps a 2018 trip.We'll have to see.

* purchased the wheels
*I have axle stock on hand
*I have 1-sheet of plywood on hand
*Tom Burkland is assisting me with regards to model attachment considerations for the tunnel.
*I'll be sending out a set of drawings to DARKO so everyone can see what the 'plan' is for the project.
*I've already widened the body to accommodate a 42-inch front track to fit the front load cell support troughs.
*I bought fresh blades for the recip saw and will be cutting up both the belly tank and Bonanza fuselage for scrap,raise a little cash,and make some room around the place.

To quote the Beatles (Revolution), "We'd all love to see the plan." How much were the wheels?

With a scale in 32nds of an inch you can measure to 1/64th, or even 1/100th. I used to do that when I was making Geodesic dome kits. I got 1/32nd accuracy over 40ft. I doubt I could today.

*I'm doing a 3-view drawing to send to DARKO.It' not to scale,just to give them an idea and work out attachment.I hope to get it out tomorrow and I'll try 'n get it scanned for Saturday posting here at the forum.They're not meant to be a blueprint and a bunch of morphing is going to happen to respect all the project constraints.Compromises.
*The wheels were $7.50-each plus the governor's tribute.They'd be equivalent to around a 205/ 75 R-15,like on the truck.Solid rubber on steel wheels,and a tread pattern.They're really stinky too! Really nasty odor!
Since most of the wheels will be concealed within the fairings and skirts I feel like there'd be some wiggle room here with respect to dimensional accuracy.

I talked to Layne Christensen at DARKO by phone this morning.We went over attachment details.
I finalized the drawings,went ahead with dimensions.
Layne said that once they see the images and numbers,that they'll come up with an attachment strategy for me.
I couldn't build what I wanted and have it fit onto the load cell bearing members directly and still be able to transport it within the bed of the truck.
I reconfigured the drawings to fit the dimensions of the T-100 at full-'Template.'It's an abomination compared to a 'pure' pumpkin seed,but better represents 'real' vehicles.
The small frontal area of the model will reduce the maximum airspeed in the test section,but it will be enough for a supercritical Reynolds number,TBL, and stable Cd.
So,as to paraphrase Preston Tucker:'All I need now is a model!'
I'll also have to cut my aeroshell to add a rear hatch section,otherwise I'll never be able to get the model in or out.

Here's what I have so far.Will postpone fabrication 'til I get the thumbs up from the folks in Utah.

After a month I finally called up to DARKO.
The drawings arrived okay.Layne gave 'em to Tom to look over and Tom's so busy we haven't heard from him yet.
I'm not concerned.There's a lot of time yet.

As you approach the speed of light that's true. But the fineness ratio goes all to h*ll.

And you experience wallet dilation

Speaking of which, I'm trying to keep the car on the road I'd like to haul my 1/3rd model on. I'm starting to think I should park it and save the money to rent a pickup.

I could make the model recyclable and rent one way, then take a bus home.
