widow build, need help

[tmaxx_man87]

heres my widow chassis build as you can tell im going cheap with it, the wb is almost 14' and i know thats too long but my prablem is that the axles sit off to the side from the chassis, i mesured everything and its all right, could the length be making the axles sit off to the side? will making it shorter fix all the torq twist im having also? thanks everyone and offroader5 for the template, well ok it wont let me upload pics... dont know how...

use something like photobucket, and use the "img" code.if the axles are to the side id geuss your links arnt perfectly even? im not really sure how to get ride of torqe twist.

What'd you use for the chassis? How'd you cut it out? If both chassis plates aren't symmetrical, that cut throw off your axles.

Hard to really tell without the pics, but here's some checks:

• Check your lower link lengths and make sure they are all the same.
• Check the mounts on the axle and make sure they are in identical positions.
• Do you have the upper links installed yet? If so, make sure those are all the same length. If the uppers are off by even the smallest bit, it will throw off the axle alignment because they are more triangulated than the lowers.
• Are the uppers mounted in the same hole in the chassis at each corner?

I'd be a bit concerned about the 14" wheelbase and finding shocks long enough to work with the Widow design. If your shocks are too long on this design due to the wheelbase being so spread out, the shocks will lay down quite a bit and won't actually do anything. It will allow wayyyy to much flex, and cause alot of torque twist.

If those ideas don't help, get some pics up so we can see exactly what you've got going on.

[/IMG] ok, heres the pics, i mesured the wb again and i was off idk what happned i think i was just tired lol. its more like 13.5 and it has alot of flex, like more than 90 digrees... oh btw its made of cutting board and there the exact size i bolted them together to sand them exactly the same...

there the others didnt work...

Can't really see much in the pics, but it's definitely too long of a wheelbase for the chassis design. It forces you to use way long shocks which won't give good handling characteristics.

If you want to keep it a longer wheelbase, you'll probably need to mount your shocks like many of us do on the supers. Instead of attaching the lower end of the shock to the axle, you could bring it inward and mount it directly to the lower link. Not the best solution, but if you're dead set on running the rig that long, you'll need to either figure out a way to bring those shocks a bit more vertical, use a different chassis (longer), or even scale up the template and just make it bigger.

Check my templates page again...maybe the Widow LP would work better for ya since it's a bit longer between the shock mounts. Also due to it's shorter height, if you had to scale it up to make it larger to fit your rigs size, it wouldn't make it overly tall.

ok, ill shorten it, what should i make the wb to make it work right? im having so much torq flex that when trying to climb a small angle the right front wheel comes up and flipps the truck over...thanks fo the help, this is my first crawler

[Offroader5]

I have mine set at the "standard" comp legal max of 12.5"...as do most of the 2.2 guys. I have a little bit of the twist also, but it doesn't start to bring the tire off the ground until I'm climbing something steep like 50-60 degrees. Much of it would be helped by adding some weight to that particular wheel/corner so it takes more force/torque to lift it.

[tmaxx_man87]

ok, shortend the wb to exactly 12.5, removed the shock spacers and it actually made it worse, the wk with flipped chassis and extended to 12.5 did better than this set up, i must be doing something wrong should i take the springs off and use some fuel toobing on the shocks? any info would help, what about internal springs? is there some info i can read about that set up and how it works? thanks alot everyone

[Offroader5]

When it happens, is the rear shock opposite corner from the lifting tire compressing quite a bit? What weight oil are in the shocks? You may have to thicken up the oil a bit. I'm running full droop with no springs at all...internal or external. I tune it with oil thickness and valve disks inside the shock.

[tmaxx_man87]

well, i decided to try a diffrent chassis so i made the manta chassis, put it all together and same prablem as before, it has a 11.5 wb, i tried thicker oil and no shocks i used 90wt oil, and it does same as before, when it gets on a hill the front shocks extend all the way and down the hill it goas... the oil only slowed down the process a little... no torq lift though...

The next thing i would try would be to put the springs back on, but put stiffer springs on the rear shocks
