Stock is as the vehicle ships. Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart. Not published means it exists but no source we could find prints it.
How these numbers were settled
Brushed Type 540 motor, so no kV and no cell rating.
- Tamiya's printed 'Gear ratio' on TT-02 kits is the COMPLETE motor-to-wheel reduction, not a transmission constant: the TT-02 Type-SRX page prints 6.55:1 'with kit standard 27T pinion and 68T spur gears', which forces an after-spur constant of 6.55 x 27/68 = 2.601.
- That same 2.6 reproduces Tamiya's own published pinion windows exactly (kit-standard 70T spur gives 11.38:1 to 7.28:1 = 16T to 25T; the 54500 68T high-speed spur gives 9.82:1 to 6.55:1 = 18T to 27T).
- This page's 8.27:1 with the kit-standard 70T spur therefore implies the 22T kit pinion, and (70/22) x 2.6 = 8.273, within 0.04% of the printed total.
- Tamiya states 'ESC included for export' on this kit: Japanese-market boxes are supplied without the ESC.
- No advertised top speed is published, so no speed check is possible.
