12th car veering on power

[beale]

Had a CRC Carpet Knife V3 for a while but only ever ran it during breaks before finals as normally run mini, TC a few of they drivers got a heat together of GT12s so thought stick a shell on and join them to make the numbers up.

Problem was as soon as you hit throttle from stop or slow corner it veers violently to the left, started to get used to it and the car is fast obviously should be faster than GT12 as it is a pan car but was such a handful was just hanging on, any ideas?

It is set up close to Mark Reinhard of 2006 but not sure what his oils were, diff tightness etc.

So many things...

Is the diff tight? A ball diff in a 12th car must NEVER slip. Despite a lot of rubbish to the contrary, any diff slip will give you handling problems.

Are the rear wheels at an equal distance from the centre-line of the car? If they aren't, the car will veer on acceleration.

Do the front wheels have equal 'droop' on both sides? If one has more than the other then the car will veer...

Have you checked the rear pivot balls are properly aligned and there is complete freedom of movement on the rear pod? Strip all the rear of the car off until you have just the motor plate, pivot and side links in play. Gently and slowly move the motor plate from side to side. It MUST be completely free and not notch about the middle of the movement. See the original instructions (here) for details. This is the key to handling on a link car.

If none of this helps come back and I'll give you another list! HTH

Thanks for that yes did notice that evening the droop on the front was different and diff is probably too loose
