By comparing the sprocket size between the Pershing(small sprocket) and the Tiger(large sprocket), I would think the Pershing would be the fastest and the Tiger the quickest. An easier way to understand this, for example, is how a 10- speed bicycle gearing works, or the rearend gear ratio between a drag racing car and an open road racer.
You might realize that by installing more powerful motors. My Pershing ran twice as fast as Tiger with Graupner Speed400s until she went offroad and blew a transistor. The motors exceeded the capacity of the board.
