alright i am having problrms with torque twist so can anyone help me out
thanks

Do you have any pics of your set-up? It's easier to help if we can see what's going on.

levi steele · 11-05-2007, 07:15 PM

my computer is to slow to post any kind of pics
but what about troubel shooting

Steveakus · 11-05-2007, 07:31 PM

you lifting front right??

RXcrawler · 11-05-2007, 08:46 PM

Get as much weight off the chassis as possible and stiffen the left rear shock would be a good start. What kind of chassis are you running?

It's easier to troubleshoot what you can see.

Link geometry can help manipulate torque twist,if set up correctly. Thats where the pics would help.

A naked side shot sitting flat footed would be best.

I didn't get any pics of your truck yesterday Levi, or I would post them up for people to see.

I wish I lived closer to you, I'd stop by and give you a hand getting it worked out.

levi steele · 11-06-2007, 12:25 AM

we can figure it out at the next comp but sense i put that 3 cell in it im pulling out a lot more torqu from that outrunner but thanks for that bat

I understand that, I have went through the same issues over and over again, trial and error is the only sure thing, but most quick fixes are going to raise some pros and cons,

just put your crawler on a flat bench or table and secure a rear wheel (either hold it or strap it down) and just torque the motor enough so you can see the twist happening. This helped me to determine angles and such. Every crawler is different too.

Options that I know of:

**My #1 = Add weight (inside) the right front tire
I use wheel weights that stick on automobile rims.

**Raise the upper link angles on the axles = make adjustable plates (three holes at each mount) so you can dial the front and rear in,

**Stiffer spring and oil on rear left shock

hope some of this helped, I feel your pain

mine still torque twist a little but they don't back flip nearly as much anymore.

Steveakus · 11-06-2007, 05:19 AM

I still havent totally figured this one out if any of you have any other Ideas I could use the help......

Side

side

Rear

Front

Steveakus · 11-09-2007, 05:32 PM

anyone up for some help here?

Tanis · 11-09-2007, 05:43 PM

First thing I would suggest, is get your rear upper links angled the other way, down from the axle to the chassis, instead of up from the axle to the chassis. Another thing that could help is to try a stiffer spring on the left rear shock and some heavier shock oil as well. I kill torquetwist with my link geometry, but it looks like it would be tough to do on you setup, unless you drop the chassis a bit.
Another thing that will help, is to get as much weight off of the chassis as possible.

Which side lifts?

You can try a stiffer spring or thicker oil in the opposing rear corner.

Steveakus · 11-12-2007, 04:40 PM

Cool, thanks for the info, Ive been dabbling lately with different upper links cause the old ones are one piece, I think two separate links will help some, Also I added about 4oz more weight inside the left front and that helped the torque twist, I would rather not adjust shock spring rates if I don't have to. I am working on figuring out a way to mount the battery elsewhere, thanks guys, I will post some pics soon and see what you think, and see if it helps.

i gave up on my tuber and bought a sw3 my next tuber will mirror the sw3 link and shock placement. sorry bender.
the sw3 has NO

torque twist, ( iused all my tuber parts no TT)
i also have tried everything shocks springs oil.
in my opinion you need low cg and shock and link placement is critical

levi steele · 12-06-2007, 09:45 PM

cool thanks guys iv got an sw3 coming so i should be set
