Mini-F Chassis

The Mini-F Chassis.

The Mini-F Chassis (ミニFシャーシ) is a chassis of Mini-F cars released by Tamiya in December 1991. It debuted with the release of Lotus type 102B.

General info

The Mini-F Chassis featuring the one-piece chassis frame, with the usual rear-motor and mid-batteries setup. It is longer than the Mini 4WD chassis.

The underbody of the chassis is mostly flat, with the front wheels and front driveshaft being supports by the fixed, sandwich frame. It has the rear-wheel-drive drivetrain, with gearing is similar to the bigger 1/10 scale R/C F1 cars. The change of both pinion gear and spur gear are requires if user wishes to changes the gear setup. The motor was mounted onto the rear with the motor mount.

Body attach method is similar to the Mini 4WD car's, with the Mini-F car's rear spoiler doubles as a bodycatch.

Due to the chassis frame design, the chassis itself is somewhat soft and fragile. The front sandwich frame that holds the front driveshaft and front wheels is also fragile, meaning it can breaks under heavy impact. Futhermore, it is impossible to lubricates the pinion gear and spur gear without ruining the fair play as they were exposed to the circuit even with the bodyshell attached.
