I found that mine had some issues with the suspension and steering, the steering knuckles bind at full lock and the lower arms have just under 0.5mm of play when built according to the manual. Weird, but fixable.
Mine is primarily running on-road (tarmac rally, drift, "touge") so I left out the dust/dirt protection gear and it's starting to look a bit more like the old TA03.
Because I'm using lightweight servo, ESC and receiver though the weight balance L/R is completely off, and I'm contemplating having a new base chassis made to move the battery farther towards the centerline. Please LMK if anyone's interested!
