Limitless The ideal body for speed runs

[LibertyMKiii]

Ah..
Okay, that's very doable.

@LibertyMKiii ,did you regain access to Fusion360 yet..?
or do you mind if I take a crack at your concept idea??

Yes I'll shoot you a text so we can talk about it further.

Took a side profile shot of the Limitless and used MS Paint to lay over a body design similar to what Nic Case had for his RC bullet car.
You would have to leave some room for tires to expand and some suspension flex/travel. The body could probably come a good bit closer to the tires, but I think this is pretty close to a 1/7 scale version of his car.

That would be a sick body to run.

Have not drawn in Fusion 360 in quite some time....
Was wanting to sketch up the lazy drawing above. This one has rather rigid square lines which goes against everything I know and love

Decided not to go for drawing/printing yet but made a functional cardboard/glasfiber prototype during the weekend.
It's attached to the splitter, not the body itself.

THAT looks quite good actually!

We tend to focus on our 1/8 and 1/7 platforms. They are easy to run with minimal tuning out of the box and very stable compared to other options.

@phildogg did a few speed runs with a drag rail years ago....

If you are looking at aerodynamics alone the RC drag rail design seems ideal. (similar to a top fuel dragster) Tim Smith has been in the drag race scene for a very long time and around the same time Nic Case was chasing the speed record so was Tim. He managed a few high-speed runs in the 170s and 180s but the car often turned sideways and would crash. One crash went right into his setup tables and tent which was pretty violent. Luckily no one got hurt. Within the last year, he ran in the 190s so speed runs are still something he does on occasion.

There are only a handful of companies that make parts for them but is something I looked into at one point.

Drag race concepts makes some absolutely beautiful chassis

Inline motor designs

vs sideways motor designs (easier on the bearings)

 

[phildogg]

For aerodynamics you can't beat a rail. They can be tricky to run with only 2wd though.

Phat bodies UK
This is a 1/12 but I love the shape on the front cannopy to fit the shocks while keeping the rest of the body lower/slimmer.

I like that one a lot!
Looks in line with how I would re-design my body if I had the energy to do so!

Detla Plastiks gave us this body more or less with the WR Speed body.
James has proven it to 200mph so far. I have tested it one time on 3s at 119 mph. Was very stable/straight.

The key is making everything smaller for less drag. I think the Vendetta version is the way to go.
