what do u think is the most that u can mill out on a 3mm thick chassis. Its a buggy so i need to keep it relatively strong but its really heavy. Also what kind of bit on a dremel do u think i should use?

plastic, graphite, aluminum, lexan, plexiglass, what is it??

its an aluminum chassis off a gs storm. the things a beast and i realy want it to shed some weight so i was think of first cutting out some holes around the gas tank and under the engine. I also wanted to mill out the chassis so i can mount everything lower. I just wanted to know how much i could mill it out without weakening it to much...especially around the motor and diffs.

cant help ya with that one sorry im not familiar with layout of nitro anything.

wicked

Do not make it any thinner and be carefull where you cut holes out. You will weaken the chassis much more by making it thinner than you will by cutting holes out.

use a high speed steel cutter. i have a 1/4 inch bit and a 5/16 inch bit. they work very well on aluminum. dont use a tungsten carbide bit. it makes extremely tiny little splinters and if they get in your skin they dont come out for up to 5 weeks. trust me, i know.[:@]

as to where to remove material, some pics of the buggy with its components on the chassis and the chassis plat itself would be very helpful.

If you're going to insist on "milling" out the chassis (since you're using a dremel by hand, it isn't milling since you aren't using a milling machine), take a look at the Storm Pro chassis, which is milled. The slot locations and the amount of material removed will determine how much weaker you're going to make the chassis. Personally, I'd live with the extra ounce or two. BTW, the Pro chassis does not mount anything lower than on the stock chassis, you want maximum thickness around all areas in which you mount components.

I would buy a storm pro chassis before ruining the stock one.

k i decided its not the greatest idea to mill out the chassis. As is the chassis isn't the strongest. thanx for everyones input.
