The other night while working late I came up with a unique method of producing a chassis with a narrow bottom and wide top. This chassis can be easily produced with traditional methods. This chassis doesn't require metal parts to be bent which has been the method others have attempted.

This chassis also has the narrowest lower profile available, right around 1"

The chassis is fairly low profile, less than 2.7" from bottom of the skid to the highest point.

This is a very unique design and one I am excited to get the prototypes back in the next few days.

Specs:

Chassis - ARC
Axles - Berg
Links - Axial Machined High Clearance
Shocks - Losi Crawler Shocks
ESC - Tekin FXR
Motos - Holmes Hobbies 35t
Servo - Futaba S9156
BEC - Castle Creations
Wheels - Custom DNA 10 Bolt Thrashers
BTA - Harley Designs
Knuckles - TCS Prototype High Steer Knuckles
Lockouts - Fubar Crawlers
Tires - Hot Bodies Rovers (Med)
Foams - NWTT All-weather
Battery - MaxAmps 2100 3c

Thanks to all my sponsors!

Very Nice Josh.

You definitely have a different way of thinking.

Wow!

Where do I send PP?

damn good idea, one of those things where you say "why didn't I think of that"

Harley · 01-20-2009, 11:36 PM

Compared to a stock-ish AX-10 Chassis:

I am probably over-looking something but how would you use the first set of 3 holes in the chassis for the upper links with the yellow part blocking the back?

1/8" spacer between the rod end and the chassis.

Looks like an erector set, but I like it.

Got ya.

I was thinking it was thicker at that point than that.

The size is deceiving without something else for reference. It will be pretty tiny when done.

wow!! looks great!! thats perfect design

i really liked under side skid!!

Nice creative thinking.

I am sure you will do testing, but if it needed to be stronger, the upper part of the yellow could expand to cover all 9 link mount locations.

killjoyken · 01-21-2009, 06:15 AM

Not bad. I mean, it's no Rock Force chassis, but maybe after another 3 years of development it may work.

j/k Nice job. I likey.

So when is your BTA/knuckle setup going to be available?

binaryterror · 01-21-2009, 06:43 AM

Thats a nice design. Very innovative!

Will all the components and screws cause it to weigh alot? I'm not sure it would hurt, but honestly thats the only possible downside I think anyone could find.

Actually that part is just cut from a piece of 1/4" material, expanding it would mean you would have to widdle that piece from a large chunk of material. I could always just take away the other 6 holes and just give those 3 for anti-squat adjustment.

I was thinking that maybe I should just bolt the Rock Force chassis to the top of this one

No idea on the BTA and Knuckles.

It is definitely more complicated and has more components. The chassis is small overall though. The upper section may be made from carbon fiber for style, strength, and weight savings. The "boat sides" are only 1/16" material, and the skid and "Ribs" are 1/4". The Skid is so small that it will weigh less than a traditional skid so there is just that very small amount of material above the skid that would be "extra" over any other chassis.

Thanks for the explanation...can't wait to see you build one of the prototypes up!
