Yeah, a cooked bearing can really throw off the car. Need a Mazda 6?

Was this at region 8 regionals? If it was than it could be that the track conditions was changing. It seem to have good traction one round and then ok traction the next and then it seemed to have dry spots the next.

I took my Pro4 to a regional event this past weekend. It did some wierd things and was wondering if anyone had experienced this.
There was one time in particular where I took my car out for practice after making some changes. The car handled great. The best it had been all weekend. After I ran a few laps of practice, I took the car off the track and back to my pits. I put the car on a setup station to check the camber and toe. I then checked the ride hight and tweak. Did not make any changes to it. The next time I took the car out, in a qualifier, it handled like doo-doo. It was not even close to the same care that I ran in practice.
Does anyone have any ideas what might cause this?
Oh, I was running foams on ozite with the 3mm BMI chassis.
Thanks

Erik: I'm sure during your R&D of the Pro4, you must have tested different battery positions. What effects did you notice when running the batteres toward the front (approx 15mm) vs running towards the rear in relation to where the battery sits now? And why did you settle on the current placement of the batteries? Honestly, I think that the Pro4 could benefit from running the batts forward approx 12-15mm for carpet racing.
Currently the car is great on carpet, however I feel the car leans towards pivoting around the corner vs rotating. What are your thoughts? Thanks,
Jeff

I checked the bearing before the race. During the weekend, I did not notice any bad bearings. That is something I am going to check tonight when I tear the car apart.

Was just wondering if anyone knows the difference between the US and Japanese Pro4 kits. I know the US version has MIP CVD where as the Jap spec has a Tamiya style CVD. Any other differences?
Anybody try the "Square" aluminum front-one way gear. My bevel gear stripped . So instead of buying another bevel gear, I was wondering if the aluminum is better.

dontfeelcold- what ive found is that the jap spec cvd, dont ware out. thee holes where the pins go through instead of being alluminium are in the axle, basically mip design backwards. i just wish that off road cars would follow this, the alloy bones in 4wd mod dont last long!

Yes, this was at the Region 8 Chapionships. I can understand the track changing conditions as the weekend went on. I just have a hard time believing the track could change that much in about an hour. But then again it was my first race on a track that size with ozite carpet.
I did tear the car down last night. Nothing broken and all bearings are in working order.
Thanks everyone for the advice.
I need a set-up for high grip carpet. Thanks in advance.
