Sounds ok depending on the jump layout. What motor and where is the motor timing set?

How many turns out from full tight do you all have your diff? Im running on carpet and my diff is little over 1/8th turn out. In MM4 this baby is a rocket.

1/8 is about par for the course. I set mine tight enough it doesn't bark and stop.

For those who are interested...Exotek has jump on the band wagon and now have USA made 4mm thick carbon fiber front shock tower with machined alum camber link mounts. There is another version for ST and SC as well.

Hey guys, I just got a new Durango buggy and I am having some issues with the steering. When I turn the buggy a certain way, the wheel that I am turning towards seems to get over extended. And when I turn it back the other way the steering links tend to bind up. Any help would be most appreciative.

Also here are a few photos of the problem.

On the front axle where are you running your wheels trailing at. If its say 4 you have to have 4 1mm shims behind the C hub. 3 would be 3 rear 1 front. I didnt know this till last night. This site helped me out a lot http://www.petitrc.com/setup/durango...ngoDEX210.html

You actually want your wheels to turn like that. The inside wheel follows a tighter path than the outside as the car rotates through the turn. It's called the ackerman effect.

Ok thanks. Any clue why the links would bind/ get stuck when moving back the other dirrection after being in this possition. I haven't tried it with a servo yet. Just played with it by manually moving the servo link.

Using your turnbuckle wrench, twist the turnbuckle slightly one way than back to ensure it's alligned in both ballcups. This might free things up a little.

You do not have shocks on the car and if you do not have the droop screws installed the arms are going to travel well past normal movement. This will cause all kinds of wacky angles and binding. Also if your camber is way out it will cause binding.

I had two of the stock plastic preload collars come loose on the rear shocks and throw my buggy out of adjustment. Was a good excuse to order the red Tresrey collars.

I had the same thing going on with mine but only if I turned the steering at the wheel if I use the steering rack it did not happen. Just my .02

Hey guys,
I'm running a 7.5 motor with a 25 tooth piņon gear on stock spur. The esc and motor is cool to the touch after a full pack but I find top speed kind of slow for a 7.5 turn motor, am I under gearing? Any suggestion on what piņon to use as I don't want to spend too much on trial and error, I'm already way over my budget.
Thanks

im running 81/23 on an 8.5 motor and my buggy is fast.i would think if your spur is an 81 tooth and a 7.5 motor you should be geared at or around a 21 or 22 tooth.
hope this helps.
