Competition-ready out of the kit
Third YD-2 I've built (SX, SXII, now SXIII). This SXIII generation is noticeably better than the SXII — the chassis feels more planted, steering response is cleaner, and the kit build is significantly less fiddly. My team runs these almost exclusively. The Hobbywing 10.5T combo is the standard pairing. Don't cheap out on the gyro — a good one (YG-302 or Sanwa SRG-CL1) makes 80% of the car. Build it, don't skip the hardened gear swap, and don't expect it to be forgiving — it's a competition chassis, not a toy.
