NACA 66 Special A/BGS

[Graham in Aus]

This is such a special build and great of you to share all the details, 62 days to go!

Looking forward to seeing it on the salt!

Rob, are there two parachute boxes, I see something ahead, and behind the axle.... How will the doors work?

Keep up the good work, loving it!

Amazing build guys! The whole concept just looks so obviously fast that it makes me wonder why this isn't a standard configuration for a stream liner.

One thing catches my eye here, or I may not be seeing something that's right in front of me. (That has been known to happen  ) The rear end axles look to be relatively long, with no support outboard of the differential housing, which is solidly mounted to the chassis. This area looks like it could use a little more beef to help stand up to the pounding of a rough track.

Maybe something like the support rod that runs from side to side under the diff on a Harley Servicar diff, with turn buckle adjusters on each end to provide preload adjustment. From here it looks like you could build it to fit inside the aero package.

Like I said, just an idea that's probably worth everything that you paid for it.

Thanks Wizzbang!
You are correct about the axle being very long. This is one of the reasons that the spars for the rear end are shaped like "I" beams (3 per side).. Also the skin of the wing is extremely strong and will be mounted with many of the right kind of fasteners. There will also be some other sheet metal plates that will be installed under the wing skin and will brace and stabilize the spars to keeping them from buckling under the extreme load. We agonized over this issue and I feel we have it under control.

Graham,
We are still working out the details on how the chute doors will open but as of now they will be hinged from the side.

[WhizzbangK.C.]

Ahh, I see it now. My eye wasn't seeing them as "spars" in the load bearing sense, but more as formers just there to support the skin, with the outboard former supported by the axle. 

It all makes much more sense now.

Is that "THE" Ted Wolf?

Yes it is!

Here is the paint scheme we decided on.


Using single stage Hot Rod Flatz for this year.
Maybe we will have time for a really nice paint job next year.

Weekends progress on getting wings mounted.

It's coming together nice Rob!

I'm frustrated on how slow things are happening. I set modest progress goals for us (at least I think they are modest) an we consistently miss them. Think we have about a billion hours in it so far.

welcome to LSR 
actually most of us understand, just keep plugging away.

You may start to whine when it has been 12 years.

My Rampage certainly does not meet the high caliber and craftsmanship of your car. 
If it's any consolation, I've been working on mine off and on for four years!

Nice.
