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
Second-generation Limitless roller, a distinct SKU from the ARA109011 V1 roller and mechanically different: Arrma prints Internal Gear Ratio 2.8:1 for the V2 against 3.3:1 for the V1, so this is not a re-box.
- Arrma's spec list gives Completion Level Roller, Scale 1/7, Gear Pitch 1.0 MOD, Internal Gear Ratio 2.8:1, LiPo Compatibility 4S/6S/8S, Tire Tread Hoons, Tire Compound White, Wheel Hex 17mm, Wheel Width 1.69 in (43mm), Wheelbase 15.98 in (406mm) and Top Speed 110+.
- Motor, ESC, radio and battery are sold separately, so KV and cell count do not apply (the 4S/6S/8S line is a chassis and battery-tray compatibility statement, not a stock ESC limit, because there is no stock ESC).
- Horizon's 'needed to complete' list includes a pinion gear, so no pinion ships and there is no as-delivered final drive; both are marked not applicable rather than guessed from a buyer's build.
- Only the 39T spool is community-sourced.
- Arrma does not print a spool or spur tooth count for ARA7116V2 and its exploded view is an image-only PDF, so the 39T comes from two non-manufacturer sources that agree: a parts reseller breaking new ARA7116V2 rollers lists the stock centre gear as 'Spool Gear Set (complete shaft spacers cup) 39t Mod 1', and an ARRMA RC Forum gearing thread for this car has posters stating 'the stock spool which is 39t'.
- This is consistent with Arrma listing 29T, 34T and 39T Mod 1 spools for the Limitless/Infraction platform.
- Everything else is manufacturer-published: the 2.8 transmission and axle ratio, roller status and 110+ claim are Arrma's, and the 100mm tire is manufacturer-corroborated: Arrma's Hoons tread plus 43mm wheel width matches the dBoots Hoons 42/100 2.9 belted set (42mm section / 100mm diameter), whose Horizon page prints 'Overall diameter: 3.94" (100mm)'.
- The whole sheet is graded community because the tooth count is the weakest load-bearing figure.
- No gearing check is possible without a pinion, and no speed check without a motor.
