MA Chassis

The MA Chassis (MAシャーシ) is a Mini 4WD Chassis released by Tamiya in 2013. It was first used with Blast Arrow.

The MA Chassis is essentially a MS Chassis with many aero-dynamic designs of AR Chassis. The chassis is now in one piece instead of 3-pieces the MS Chassis was, and like AR Chassis, the secondary parts were molded in low-friction POM plastic, and eliminate the brass bearing parts. This improves the chassis's acceleration performance.

Also borrowed from the AR Chassis is the rear skit bar.

The side guards, which absences from previous chassis since MS Chassis, has also returned, allows users to installs stability poles or mass dampers on them. The front and rear bumper has been extended, so cornering stability is improved.

The gear/motor cover parts use the slide-lock mechanism, so it is easy to maintenances the machine. The gears and pinion gears remains the same as MS Chassis.

It performs much better than the MS Chassis. and is better than the AR Chassis in stability performance thanks to its midship-motor layout.
