​FASTLANE Recommends our Custom Wound TP5860 1440 and Alien ESC with the 2028 mount on 8s.

Everything on the Chassis is redesigned. 

Pictured below is the world's first ​MUGEN MGT7 CARBON FIBER 360mm wheelbase chassis. A one of a Kind cross breed offering a wheelbase the same as the famed Kyosho Inferno GT2 that has triumphed over Mugen in High Speed Runs until now. The added Chassis length has given characteristics to handling in performance that has brought this state of the art chassis to the forefront of today's Radio controlled technology. With improved aerodynamics and our proprietary central mounted center diff it allows two batteries to remain on the chassis without additional apparatuses attached causing wind drag and added weight. This chassis weighs less than the stock chassis, its longer, thicker, and stronger, and certain to handle those high speed 175 mph impacts. Add our custom Delrin battery trays, Custom drive line, front Bumper Assembly, rear diffuser, and additional lightened high strength add on parts with your favorite Delta Plastiks 360 mm body that we keep in inventory. We can build you an amazing MGT7 ground up that will put your friends to shame in the high speed run game. Bolt on that TP Power 8s, 10s, or 12s motors. Whatever your budget allows we can help you obtain. Text us any time at 1-833-4RC-CARS to put together a Custom build sheet for you.​ Custom Carbon Fiber Chassis's are Manufactured right here at Fastlane Hobbies for any application. We use Industrial Military CF unlike any other Hobby Company our Carbon Fiber is the Highest grade available and far superior to anything else used on the market. It is 4.2 mm to 6.5 mm thick depending upon application and significantly lighter than a 3-4 mm alloy chassis. Chassis's and components sold separately or in custom builds.

The XO-1 may be the Protégé that has been over looked since its debut. Because of it we have been inspired to build an all new 1/7 Kyosho Inferno (pictured above). A Full on Carbon Fiber Chassis Made from Industrial/Military Grade CF that is not only unbreakable this Lightweight platform has revamped the car as we know it. With JX 425oz servo upgrade, CF shock Towers, CF a-arms, G-made custom shocks, forward mount center diff with side by side battery trays we have now implemented weight forward and balanced out the failures left aside by the manufacturers that enable rear heavy rc cars imbalanced left to right, corner to corner, it now sits as a truly optimal Speed Demon you will enjoy..
