Thank you very much for viewing! We sell products created by incorporating the know-how gained from winning and placing in numerous competitions. This product is a set of two gear covers that reinforce the normal gear cover 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 driving at a higher speed range. We have received many happy comments from purchasers, such as "The top speed 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, 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. The product is a new item that has been processed, but it is considered "like new" because it has been processed. When attaching the battery holder, the battery holder needs to be modified. (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 installed. If you have any requests, such as wanting the Tamiya logo on the carbon to be hidden from view, please let us know in the comments before purchasing. (Logo hiding is free) (Matte polishing the carbon surface is +300 yen) If you purchase multiple items at the same time, the price will be reduced by 210 yen for the second item onwards, so please let us know in the comments before purchasing. #GearCover #CarbonGearCover #ReinforcedCover #ReinforcedGearCover #Mini4WD #MachDash #HyperDash #msChassis #Tamiya #msFlex #MS Close
