To ensure the quality and accuracy of the products, the chassis have been revised and tested many times before production. The chassis(s) for NT-1, 3R/3S and velox V-10 will be released shortly.
Thanks for your attention but the requirement of kyosho seen not so large, the profit may not enough to cover the cost for development, therefore not consider making M3 chassis in this moment. However, we will be interested for such project if the market of M3 increases in the future.
