I ran mine last night at a club meet. Rookie mistakes meant I did not finish (or start 2) qualifiers, but when the car was on the track and the tyres were warm the car seemed really consistent and predictable. It is definately a smoother car than the Pro 4 and felt nice throught the evening. I was not expecting miracles from it, but it did not dissapoint. A few small changes wil have it running really nice. Also by "predictable" I do not mean slow, just nice and smooth.
Jonathan. P.S anyone know if you can get diff 'kits' like you could for the Pro 4. I need a diff for the front.
