Primal RC QS Quicksilver Electric Dragster Roller

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.

How these numbers were settled

Brushless-ready roller: motor, ESC, radio and batteries are not included, so KV and cell count are the buyer's.

• Primal recommends its own 960KV 1/5 motor (PRQS66082-18P) with its 200A ESC or a Mamba XL X.
• The product page gives a 17 tooth steel pinion and a 54 tooth nylon spur in the box.
• The rear axle runs a locked differential whose tooth counts are not published, so the ratio after the spur and the final drive are left blank.
• The tire figure is the driven rear slick, printed by Primal as 7.25 x 4 in (184mm); the fronts are 3.25 x 2.125 in.
