38 mph. on factory gearing, AFTER BREAK-IN it starts very quickly, (1-2 pulls) and you hit a sweet spot for the 'storm when you asked about durability, it is likely the toughest st on the market! It was my first nitro also, and I loved it so much I bought a savage too! Hpi has a reputation for building a very durable truck, and that's why I chose these two. Only downfalls are: short runtime and weak servos, I installed a venom 6v hump pack and a hitec 645 servo (steer) in mine, problem solved! As for run time, that's why I love nitro, it takes 5 seconds to refuel.

Btw, I know nothing about the riot.
