Fish Tailing issues

[Grumpy Racing]

I just put the finishing touches on the new pure stocker, had it aligned just right and looking good (ok good for me) ran it down the track with great results on the slope. As it pushed through the curve to my shock and horror, MAJOR fishtailing going on!



I've not had this problem in the past with my other cars. The center of mass is 3/4 - 7/8" in front of back wheels just like others I have done in the past with no problems. I toyed a bit with the car and have had the same results. Any help would be very welcome.

I've had the same issues grumpy

take a look at Emerson's suggestions on rear wheel alignment.

i have worked allot lately on rear wheel alignment and have made a little progress.

good luck

Grumpy, I can say for sure that Ive had this issue. Mainly its caused by one wheel working against the other. Try taking wheels off and spin by hand. If one wobbles then its a wheel, if all wheels are good then its alignment. With the center of gravity that you mentioned, I would say its not too much weight in the back. I hope this helps and good luck, Tory J

Did you drill the holes yourself? Possible that the holes are not accurately aligned. Also what Derby Doc said, check for wheel wobble. I would agree it is either the wheel or alignment. I would lean toward rear wheel alignment.

Thanks for all of the help everyone!!!! ;D

I did what I could for that poor little piece of pine let's hope and pray that I don't turn the track into a 30+ foot pinball machine!!! However, if I do you will all get the chance to see the carnage!!!

Lots of luck to you all tonight!
