Thank you very much for viewing! We sell products created by incorporating the know-how gained from numerous tournament victories and awards. This product is a reinforced gear cover, reinforced with carbon. (Logo hidden) By firmly holding the motor with carbon, drive loss is reduced, and the rigidity of the center chassis is increased, allowing for走行 at a higher speed range. We have received many positive comments from purchasers, such as "the speed range has increased," "the acceleration (torque) feels better," and "the body can be mounted lower, increasing stability," and the repeat purchase rate is quite high. Also, compared to normal gear covers, there are fewer problems such as falling off or breaking. We use this cover in important race finals and official tournaments. A common question is, "Will the carbon and plastic adhesive come off?" We use a very strong adhesive, so the adhesive part is unlikely to come off. This high strength is one of the reasons for many repeat purchases. This is a processed new product, but it is considered as "like new" because it has been processed. When attaching the battery holder, the battery holder needs to be processed. (The processing procedure is shown in the image list on the order-only page.) It's easy to do, just cut it with nippers. * Cooling shields cannot be attached. If you have any requests, such as wanting the carbon Tamiya logo to be hidden from view, please let us know in the comments before purchasing. (Logo hiding is free) (Matte polishing of the carbon surface is +300 yen) If you purchase multiple items at the same time, the second item onwards will be -210 yen, so please let us know in the comments before purchasing. #GearCover #CarbonGearCover #ReinforcedCover #ReinforcedGearCover #Mini4WD #MachDash #HyperDash #msChassis #Tamiya #msFlex #MS
