So recently I purchased a TA05 v2R chassis coming out from a old TB02 chassis. During initial set run, I noticed the car exhibit extreme left on power over steer and extreme right on power under steer. The problem exacerbates with the use of drift tire. The car would literally do a standing donut with the slightest left turn input while right turn does just fine. I've encountered similar problem with the TB02 chassis before however the problem slowly faded away. Anyone with any idea what I'm doing wrong??

First, check everything is rotating freely. I'd check the shims on the wheel bearings, as sometimes when you don't set it right, it pinches on the bearing and jams it up. Also check that the top ball cups aren't rubbing on the wheels.

I've check every where for signs of binding but found nothing

1) measure toe caster and camber and make sure everything is precisely symmetrical right to left

2) the car is VERY sensitive to droop. again make sure that's also symmetrical right to left.

4) check your steering throw right to left, adjust your end points so the right and left circles are the same

3) get a set of Hudy balancing pins and use a caliper and a small drill bit to make balancing holes;

I'm currently using a TA-05 ver.II R in VTA. I'm using a spektrum SR3100 RX, a Savox 1258 servo, a novac SS 25.5 motor with the Havoc ESC and Orion 25C Rocket Pack Batteries. I needed 120 grams on the battery side to balance the car.

If you do all of that the car should at least behave the same way making right or left turns
