RC MAKER Carbon Slimflex Chassis HARD 2,2mm for Mugen Seiki MTC-2 / MTC-2R

RC MAKER Product Description:

Introducing our SlimFlex HARD Carbon Chassis for the Mugen MTC-2 and MTC-2R!

The Mugen MTC2 has a unique chassis design that is already very flat. In this case, we decided to work on the flex point of the chassis to make sure we could optimize the flex and also the stiffness of the chassis.

This particular chassis in the HARD version features a much stiffer carbon weave that greatly reduces flex. The flex of this carbon chassis fills a large gap between a standard carbon chassis and an aluminum chassis, making it the optimal choice for medium traction asphalt and low traction carpet! Often track conditions can lead to the need for an "in-between" option where an aluminum chassis is too stiff and makes the car too easy to drive and slower, while a carbon chassis is too aggressive or difficult to drive consistently. On this HARD version, we also removed the weight cutouts under the steering, as they are rarely used by Mugen's top drivers. This further increases the stiffness in the front of the chassis. This stiff carbon chassis is the perfect middle ground for your Mugen MTC2! 

An important change to the SlimFlex chassis is the removal of the "through" coil and diff cutouts. We cut these out only 1mm deep, which allows for a stiffer front and rear axle. This directs the flex back to the center of the chassis, resulting in smoother handling. The MTC2 does not have shock towers to stiffen the bulkheads, which results in excessive deflection of the bulkheads, which improves steering but also makes the car unstable. Thanks to the cutouts, there is now significantly less horizontal flex between the bulkheads, so you can go without bracing or with thinner bracing like our Med Flex Link or Bulkhead/Topdeck Flex Dampeners and not get as much flex in the bulkheads on the horizontal axis, but maintain "trail flex" to improve steering. In addition, the cutouts also improve aerodynamics by not allowing as much air to enter the chassis, which ultimately improves downforce.

We also removed the 0.25mm recess on the bulkheads, engine mount and suspension mounts. In our opinion, this recess significantly reduces the strength of the holes in the chassis by removing the outer (strongest) layer of carbon. This reduces the amount of material under the bolt and exposes the fibers, making it much easier to pull the bolts through the chassis in a crash. Removing this also allows the use of our brand new Roll Centre Shim Plates!

Finally, the chassis profile was changed to move the flex point of the chassis forward overall. Since the front Mugen profile is significantly wider than the rear, we widened the rear profile to a more normal width relative to the front of the chassis. This shifts the flex point forward and stiffens the rear of the chassis, ultimately providing more steering, which is almost always needed on asphalt! This widening also increases the strength of the chassis in the shock mount area, which is usually very exposed on the standard chassis.

All of these features combine to create a chassis that we feel provides more steering and cornering speed while keeping the car easy to drive and stable.

Our chassis are precision cut and countersunk on our CNC machine in-house in Australia from high quality 3K 2.2mm carbon.
