The most popular 1/10 4 wheel drive 2 speed on-road racer in the world just got better! At each evolutionary step, the Ultra has been improved upon to keep it at the peak of the RC on-road racing field. So how do you make an Ultra better? Extra speed, extra adjustability, extra toughness! The new Ultra is packed with features that have been suggested by Ultra owners: More room for the electronics, easier access to the differentials and transmission, and more suspension adjustability. The result is the best Ultra ever.
