This is a limited edition fluorescent yellow MS chassis, pre-flexed and gear-positioned! ✨️ (3 wins! ✨️) The underside features silver carbon for anti-bowing, and the A parts are black. Each one takes time, so it's first come, first served! You can use it immediately after inserting the gears and attaching gimmicks! ✨️ Having used over 50 MS chassis in the past, I've performed modifications to minimize torque loss, and there is no weight reduction on the underside of the battery holder, etc. Since it's handmade, there may be variations in the processing, but there are no issues with use. Please refrain from purchasing if you are overly concerned about details. This comes with a pre-broken-in Mach Dash motor. Please use it together! ✨️ We also handle many other products, so we look forward to your combined purchases! ✨️ Recommended bundle: ↓↓↓ Motor pin counter shaft Low-friction processed counter gear "SLIP STREAM 707" Various motors #Mini4WD #Preprocessed #FinishedProduct #MSFlex #MS #HyperDashMotor #MachDashMotor #TorqueTuneMotor #SprintDashMotor
