My Viper throttle works fine, but the steering has a slight delay before reacting, letting you run into things easily if you run it in a small place with a lot of obstacles. The steering is noisy as well. The rear axle is solid and has no differential like a Xmod. This causes squirrely handling on slick surfaces. Does ok on my smooth concrete porch, though. To be honest, I haven't run it since getting the Xmods. They are too much fun.
