Arrma Limitless

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 applicable means the vehicle does not come with it, like the motor on a roller or the tires on a race kit, or does not have one, like a KV rating on a brushed motor.

How these numbers were settled

Roller: no motor, ESC, radio or battery included, so kV and cell count are the buyer's.

• Arrma publishes Final Drive Ratio 4.17:1, Internal Gear Ratio 3.3:1 and Pinion 27T; the mating gear is the 34T MOD1 spool gear ARA310944 called out in the ARA109011 manual's exploded view, and 34/27 x 3.3 = 4.156, within 0.4% of the printed total.
• The advertised 100+ mph depends entirely on a buyer-supplied speed-run power system, so no speed check is possible.
• Tire is the dBoots Hoons 42/100 2.9 belted, whose own Arrma page prints Outer Diameter 3.94 in (100mm), matching the vehicle spec sheet.
