Notorious 6S: V5 vs V6

Same motor, new diffs, gearing, servo, shocks and chassis plate: the ARRMA Notorious 6S V5 and V6 compared part by part from Horizon Hobby's spec sheets.

ARRMA 1/8 NOTORIOUS 6S 4X4 RTR Brushless Stunt Truck (discontinued by the manufacturer) (checked 2026-09-25, source) vs ARRMA 1/8 NOTORIOUS 6S 4X4 RTR Brushless Stunt Truck (checked 2026-09-25, source).

In short

The motor carries over: both diagrams list the same Firma 4074 2050Kv unit (SPMXSM1700). (Only the V6 diagram's numbered parts list includes an ESC part, so we can't say from the diagrams whether the ESC changed.) Most of the drivetrain behind the motor was reworked. The V6 moves to 29 mm differential cases — the front/rear set goes from ARA310957 to ARA311199, and the center diff becomes a limited-slip unit, ARA310991 in place of ARA310959.

Gearing: the listed pinion goes from 12T (ARA311052) to 16T HD (ARA310963); the spur stays at 50 teeth but is a new plate-diff part (ARA310978 replacing ARAC9310). Steering: the S652 servo (SPMS652) gives way to the 25T-spline S665 (SPMS665), with a slider servo saver (ARA340204). The aluminum chassis changes from ARA320621 to a 7075-T6 CNC plate (ARA320572), which matches the spec sheet's chassis line changing from 6061-T6 to 7075-T6. The shocks move from 1000 cSt sets (ARA330621, ARA330622) to emulsion-cap sets with 1300 cSt oil (ARA-1510, ARA-1511).

Everything above is read from the two exploded-view part lists and spec sheets; a part ID that appears only on one diagram tells you the diagram changed, not how the truck drives.

Exploded-view parts diff

Every part ID on each generation's official exploded-view diagram, deduplicated and compared as sets. "Not on this generation's exploded view" means Horizon's current diagram doesn't list it; it doesn't by itself prove the physical part changed.

New on this generation (109)

Not on this generation's exploded view (75)

Shared part IDs (90)

Part IDs link to the manufacturer's own product page for that part number; an unlinked ID is one the manufacturer has no page for. The exploded-view diagrams label parts by number only, so this full list shows numbers. The system-by-system section above takes each name from the address of Horizon's own product page for that part, and nothing else.

Other comparisons: ARRMA Mojave 6S: V2 vs V3, ARRMA Kraton 6S: V5 vs V6, ARRMA Granite: 3S V3 vs 223S.
