Kyosho Ultima RB6.6 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.

How these numbers were settled

Kyosho's Ultima RB6.6 kit is the race-focused 1/10 2WD buggy counterpart to the RB6.6 Readyset, with a sale date of July 2016 and later marked out of stock and discontinued.

• The Technical Data table gives a secondary reduction ratio of 2.60 to 1 and a 76 tooth spur gear, while the pinion, motor, electronics and tires are all sold separately.
• The weight is listed as 1,620 grams.

Every figure on this page traces to one of these. Where they disagreed, the note above says which was used and why.
