Yup-I make a bunch of changes-then go to track Wednesday night and run one pack. Pretty hard to learn like that.
But at least I am trying!!!

Guys;
Raced the Car for the second time this weekend. Didn't do well at all.
Track was too loose for a front One-way, so I was fighting to keep the rear end from coming around. A Diff for the front will be coming soon.
No glitching, but every lap I was getting radio hits on the exact same section of the track. Had a couple of good crashes because of this.
Good news is, the only thing that happened was a popped camber link and lost outdrive ring (little purple one). Diff gears still intact.

I just got the HD ends from Hobby People (A302 or A320?)...the ends buckle in and pop off.
The Pro 3 came with the HD ones in the kit, the 4 came with the standard (cheesy) ones. So far, I've lost both ot the outdrive rings...I'm using Pro2/Pro3 rings.
It's kinda funny you were getting "hit" at the same place on the track. The same thing was happening to me at both SoCal and Castle...at the end or the long straight. It's been better since I changed radios, but it was always at the same place -- ripping along and the car makes a hard left into or towards the wall.

Popsracer, did you try .5mm antidive in the front? Our indoor track has a 150+ foot front stretch and at the end is a tight 180deg corner. I had the same characteristics a couple of times in the past few weeks and after I added the antidive that cured the loose feeling.
I dont understand the glitch thing because my car does the same thing with three of my monsters but that is it. Glitch in the same spot every lap. Something that was odd is the timing tower is right where the glitch occurs at both tracks. No problems running 9t-12t mods, V10R or the new monster. Good thing I love mod.![Big Grin](https://www.rctech.net/forum/classic_images/smilies/biggrin.gif)
Here is a link to the new track in Enid,OK. The pics on the website do not do the track justice as the track was not done yet.

I have a few pics that I took that are in the photo album section (enid r/c speedway-new and improved) of our regional talk site.

Doug Gaut;
No I haven't tried any of the antidive/squat settings. Tried softer springs, back to 3 deg rear toe (from 2.5), none of that seemed to help. I will definately try the antidive for my next race.
Used a different Motor this time, so I'm pretty sure it's not Motor related. Was more like a Radio hit, than a glitch (hard right,left into the boards). I ran my Pro-3 the same day and on the SAME frequency. No problems with hits/glitching.
Going to try a different Receiver and see if that helps.
BTW, wish we had a nice indoor track like that out here.
Thanks,
Steven (popsracer)

Hmmmmmm...I have a monster, too...![weird](https://www.rctech.net/forum/classic_images/smilies/weird.gif)
Oh yeah...just for reference sake...LOL...I just got two drive flanges for the "big" racecar. They're roughly the same pieces as the drive cups on the gearboxes for the shaft on the Pro 4.
$200 each, shipped, a new driveshaft (keep twisting the old stuff) is another 300-400 bucks.
That's for steel or aluminum -- carbon is $800.

Hi guys!
How can I cure the twitch on my rear Pro4 when I turn in and out of corners. Only apparent on left turns.
Thanks!

gido, as said before, you could try giving the left rear wheel 1mm more droop than the other wheen to try and eliminate this problem.
