The V1S has many advantages over the Racer 2. The V1S doesn't have any graphite or anything on it, but that doesn't matter, no one can see in your car on the track. The V1S is heavier, but has pivot ball suspension. The Racer 2 has no engine, the V1S does. The V1s has a tuned pipe, the Racer 2 doesn't, the V1S has tires, the Racer 2 doesn't. The 2 speed for the V1S is pretty flimsy and small where as the HPI box is tougher. The V1S doesn't have as many aluminium hop up parts, but who gives a krap.
Overall the V1S is a better buy. At my LHs the V1S is cheaper than the Racer 2!!
There is no law on how fast you accelerate
