Is the belt clicking or is it something else within the drivetrain? Does it click in the front of in the rear?

ProRacer03--

Check to see if your spur gear is wobbling. I've seen one or two XXX-S's where the spur was wobbling and hitting the tensioner pulley once per revolution. That might cause a clicking sound...

Just pull the pinion off or remove the motor, and turn the drive train by rotating the wheels. Watch the spur and see if it touches the tensioner at any point in its revolution.

If that doesn't get it, you might check for a bound up CVD joint. I had to repair one when I worked in the hobby shop where the owner got a little too much threadlock in there and it bound the CVD up. That was clicking like crazy until I freed it up.

Hope that helped,

Trips

Hey thanks guys that might just be it, I am in fact running the 4 degree AE castor blocks. Actually, I tried the Losi 4 degrees and the "bump" in them rubs up against my shock springs so I went back to the AE ones.

rcspeed, I'm having a hard time visualizing your stop ...do you have a digicam can you snap off a pic and email to me? [email protected] ...or post the pic here?

Yea I couldn't believe how well it ran with 3 wheel drive. The car is awesome.

Check the hubs and spindles, when you install the camber ball it can push some plastic against the cvd causing a clicking sound.
Another location to look at is the front cvd's, if there is a bind they may click at low speed.

for a 8 turn i used a 18 to 20 depending on the track and how long i was gonna run 4 or 5 min. for a 9 I would try 1 tooth higher

i am running trinity 8 doubles

Well guys just got my graphite front and rear shocktowers and the graphite chassis installed. Car looks pretty trick with all that milling. Just wish Losi would have included a graphite cover piece for the belt along with the chassis. Looks kinda silly with all graphite underneath with a big black belt cover.

Yup.

More dough for the cover and battery stap. I think they are packaged together.

Actually I believe the belt cover and the rectangle piece that fits in the chassis up by the steering bellcranks are what are packaged together.

Going to be tough going to race this weekend with all of the tragic events of this week. Hopefully it will get my mind off it for a while.........

Any one got a total graphite setup yet? If so did you weigh the car before and after the updates? How much did you loose?

Losi says you will loose once ounce if you add their chassis. They didn't say how much you would loose by replacing everything else.

Also, you guys doing the graphite, are you noticing any performance changes?

Default Which fron shocks?

I'm about to add threaded shocks to my XXX-s kit and I read that some people are using the short shocks from the cryul conversion kit for the street weapon.

So, has anyone tried using the short shocks in the front. What are the pros and cons.

Thanks
