Inferno MP11e Compatible Steel Pinion 21T 0.8M - Kyosho PNGS0821  [KY-PNGS0821]

Steel pinion suited to Inferno MP cars

The Kyosho PNGS0821 steel pinion gear is offered as a replacement, identified in the product name as 21T/0.8M/?5.0 and intended for Inferno MP Series use, for example the MP11e. This item is an RC component and not for use on road vehicles.

As a straightforward steel replacement, the pinion concentrates on resisting wear during standard RC operation and maintaining predictable tooth engagement for consistent meshing. The 21 teeth and 0.8 module line up with pinion dimensions commonly used in Kyosho MP-series gearsets; regard the "?5.0" marking as part of the supplied description.

Fitting advice: check pinion bore and set-screw locations before locking mesh, ensure the motor shaft seats correctly and tighten the pinion with the suitable hex screw torque, and inspect spur clearance after installation to prevent premature wear. When changing gear ratios, remember pinion tooth count directly affects acceleration and top speed, so pair changes with appropriate spur gear choices and methodical testing.
