More Tuber Questions....

[mrpink]

TUBER RULES :

-2.2 class tube chassis are allowed with the following restrictions. Chassis must be at least 8"long, 3"wide, and 3.75"tall, the roof must be raised from the main chassis to resemble a cockpit, and it must have solid hood, roof and sidepanels.

so by those rules.... this would not be a legal tube chassis design:



I am looking to build another rig and love this design- but with the "solid hood" requirement I am guessing it is outlawed, or is it? With it meeting all other requirements (size, resemble 1:1, etc.) and the back portion being described as a "solid hood" would it be allowed to run?

hey, if the 1:1 guys are doing it, why cant we?

It looks fine to me, he has a solid hood.

ok, maybe at first I was taking "solid hood" as meaning a "solid hood line"

thanks for helping me read, and not think ;)

[xjwalt666]

yea to me i would think that if it looks like 1:1 and has a solid hood portion over the engine area it would qualify.

[Gimbal]

Cool. I was wondering about that. For me it's hard to stuff a "hood" between the front shock hoops. The rear is much easier because no rear steer. More room to work with

Just cuz the "hood" is in the rear don't make it any less of a hood.

[bulfrog]

hood, bonnet, cowl, cowling
protective covering consisting of a metal part that covers the engine; "there are powerful engines under the hoods of new cars"; "the mechanic removed the cowling in order to repair the plane's engine"

yeah I know.... I just didn't wanna pour a bunch of time into this thing and then someone say it wasn't gonna fly over a technicality (like WHERE the hood is placed.)

So two top panels (roof and hood), two side panels, a raised cockpit and resemble 1:1... other than those design restrictions anything goes? (size is a different story)

Your suspension must mount to the tubing. Here's an example.

Gimbal's tuber design uses a removable belly pan that bolts to the rest of the tube frame. The tranny and suspension links mount to this removable pan but the shocks mount to the tube frame.

My buggy has two rails that the tube frame bolts to. My tranny, links, and shocks all bolt to the two rails and none of the suspension mounts to the tube frame.

Gimbals is considered a tube chassis while mine is considered a tube body. This is because I can remove my tube "body" and not affect the suspension. At least that is what I reasoned out.
This is a definition that just recently came up. I'm not sure if it will change next year or not but for now be sure to make sure you don't end up in the tube body definition because then your tube work will need to meet the minimum body requirements like mine.

this is my current tube chassis... based off gimbals design.


the next will be built similar (with the tranny pan) but different design above.

^ Thats hot! Where's your trans?

That looks great, and should have no problems passing as a tuber.

Chris, dont see all require panels though

get out the umbrella.... my parade is being p!ssed on!!

naw, I made the panels after that picture was taken- but they are mounted up and a fully legal tuber is sitting on my workbench

man, you rule monkeys are harsh.

[Cloak]

Like I needed an excuse to post this pic in another thread. This is quite literally the closest you can get with out being out of specs for height.

[Unholy]

While we are raining on parades...

Do we measure a tubers height from top tube to bottom tube... or do we include the skid?

[Cloak]

When I measured mine, I did it from the very bottom of the tube (before the hood or skid) to the very top most part of the tube (in my case, the support bar across the top).

That's how I understood the rules to be written.

[Unholy]

Yep, and I believe the Gimbals are tall enough tube to tube... not sure about mrpink's nor for sure how we'd call that as judges.

[Kamikaze]

Thats being a little to picky, if theres something hard that takes up space then that should be where the mesurment is taken from. If the rule says 3 3/4" tall then if the tube structure is 3 5/8" and the skid takes up the other 1/8" it should pass.
