Primal RC QS Quicksilver Gas Dragster

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

Gas powered by a Zenoah G320 32cc engine through an 8000 rpm clutch, so motor KV and cell count do not apply.

• Primal's product page gives the stock gearing as a 19 tooth steel pinion on a 55 tooth nylon spur.
• 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.
• Primal sells optional 50/24 to 55/19 high speed gear sets for this car separately.
• The 45+ mph claim is the Quicksilver page's; the Dodge SRT Demon and Angry Bee body versions list 50+ mph with the same engine, gears and tires.
