Boom Racing BRX01 AWB Link with ZIL Pickup Kit

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. Not published means it exists but no source we could find prints it.

Gearing parts

Tooth counts are the ones in the specifications above. Pitch is given as metric module (Mod 1, Mod 0.8) or diametral pitch (32P, 48P). They are different standards and are not interchangeable, even where the numbers look close. Bore is the pinion’s hole, listed separately from the motor shaft. Linked part numbers go to the maker's or official distributor's page for that part.

How these numbers were settled

The kit's parts list includes a 32 pitch 12T steel pinion, and the page says pinions from 9T to 16T fit.

• The spur is the 28T 32 pitch composite gear Boom Racing names in the page's gear ratio section and sells as part BRLC7031.
• Wheels and tires are included: the 1.55in MAXGRAPPLER Gekko, printed as 3.74in x 1.18in (95x30mm).
• The axles are BRX80 PHAT units with 30/8T AR44 diff gears, a 3.75 reduction; the ZIL body sets a 267mm wheelbase.
• The BCF2 two-speed transmission's internal gearing is not published in text (the manuals are image scans), so the transmission and axle ratio and the final drive are left blank; Boom Racing says only that second gear turns about 2.2 times faster than first.
• It is a kit sold without motor, ESC or battery, so KV and cell count do not apply.
