This is a limited edition pink MS chassis, pre-processed with flex and gear positioning. (12 wins) The underside bow prevention is silver carbon. Each chassis takes time to prepare, 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 processed it to minimize torque loss, and there is no weight reduction on the back of the battery holder, etc. Since it's handmade, there may be slight differences in the processing, but there are no problems in use. Please refrain from purchasing if you are concerned about minor imperfections. This does not include a motor. Please understand. We also handle many other products, so we look forward to your combined purchases.
