nice rig!! i think i may make a new chassis like you did, it's so simple. so you said you had lots of flex in the a-arms, what did you do to stop that? i have the same problem. so for the chassis you just took some 3"x3" square tubing and cut both ends at 45* or close to it?

nice rig

Yeah just cut both ends at 45 degree angle and drilled some holes. Well we did have to mill a hole in the top for the tranny. Very simple design I built my first clod chassis out of the the same stuff.

About the only solution I can dream up to fix the flexy arms is to buy alum. lower arms.

Truck is very heavy and solid the main problem we currently have is the Traxxas ball ends busting off. Soya was looking for metal ones of a while.

We stripped a rear ring and pinion last month. This month we stripped the rear internal diff gears. It's hardcore.

Here is some more pic's of the truck.

hope you dont mind but im stealing your chassis design.

Simple and cheap.

I dont have a mill though...so the Dremel is gunna get a good workout.

How did you make the upper link mounts? The ones on the suspension.

Ive been drawing up a similar design.
1/8" plate with a piece of 1/4" round bar screwed in that pivots.

Maxx4life · 08-28-2005, 08:49 PM

well the best i could fine is some 3x2" aluminum tubing so i'm going to use that. the only thing that will be different is the tranny will stick out of the chassis a lot, i'll have to make a strong roll bar. also for making it lighter just do some milling here and there to get the weight down. my maxx crawler with the old chassis weights 8.5lbs, how much does soya's maxx weigh?

i'll try and get a few pics up of my chassis soon, thanks for the great idea.

onefstsnake · 08-28-2005, 09:03 PM

I found 3" square tube easily.

www.mcmaster.com search aluminum.

Maxx4life · 08-28-2005, 09:07 PM

i got mine for free at a friends house, he has 5 huge bins of scrap aluminum, but he didn't have a 3x3".

onefstsnake · 08-28-2005, 09:11 PM

I dont think weight is that big of an issue. Sure a 15lb maxx is heavy..

Its all about weight placement. If your weight is down low it can help you.

There is actually a point where a truck can be too light. then you start breaking things and sacrificing structure and strength.

My "Tmaxx" Hybrid used to be under 7lbs RTR untill I went with aluminum suspension.

Well that and I'm a part of the No Mercy race team!

Maxx4life · 08-30-2005, 09:04 PM

i agree, you can make your rig too light, but i like mine at 8.5lbs, it works good and i hardly ever break any links or rod ends.

hey soya, cheak out my new chassis, it's just like yours. here.
what do you think?

o0korn0o · 08-31-2005, 11:38 PM

Is that 6061 aluminum?

onefstsnake · 08-31-2005, 11:42 PM

mine is 6063

Not the strongest but it will work just fine.

Mnster · 09-01-2005, 09:14 AM

I don't know what we used? I went to the metal store and asked for 3 inch .125 that is what he gave me. It does feel like 6061 when machining it and it does not scratch very easy.

For the axle link mounts we ditched the little round posts long ago. They would all ways work them selfs loose this truck is heavy and is driven by Soya. So I came up with 3/8 thick 1inch square piece to bolt inside the c channel shock towers. It held with 3 screws two on the top and one behind the servo. Much more solid.

Soya · 09-01-2005, 09:04 PM

Yes, it is 6061 aluminum.

and yes, this truck is driven by me, I think this weekend we'll find more things that can be beefed up

Maxx4life · 09-01-2005, 10:15 PM

can we see some updated pics of the rig?, like the new link mounts, etc.

thanks

Mnster · 09-02-2005, 10:31 AM

I don't have any really good recent pics. I'll bring my camera with me this weekend.

Mnster · 09-05-2005, 09:47 PM

Pics

I wish I would have gotten some more rock crawling pic's oh well.

Soya installed a spool for the rear and borrowed my brothers Lst tires.

Once we arrived at the crawl site Soya was very unsatisfied with the crawling performance. So after crawling a while he lowered the truck till the links where almost level. Lowering the truck made a HUGE difference it could now go places with out rolling or wheel lifting. We still have to fine tune the Beast's suspension. Even after the addition of alum hex's the truck still strips hex's. The truck puts out a lot of torque with the dual lathe motors.

Soya · 09-06-2005, 06:40 PM

Yeah that hex pic is like my favorite ever.

Maxx4life · 09-06-2005, 08:46 PM

looks like fun, just use super glue or something to hold the hexes in.

colin

microgoat · 09-06-2005, 09:29 PM

better yet, glue the hex in place and drill thru the wheel and hex using a .062 drill bit. then cut some .062 wire and run it thru the wheel and hex. use super glue or loctite to hold the wire in place. i did this on my E-Maxx (not a crawler (yet)) about a year ago and haven't had a problem (with hexes) since.
