I have the Exced Blur.

I've run it on pavement only, taking good care to break in the engine and drive components carefully. I do not jump or crash the buggy.

After about 10 runs, the drivetrain started to fall apart. Dogbones are bending as they get stuck in the universal joints which causes the wheels to lock or not get power. My buggy is a 2wd now from scavenging it's own parts. Half of the problem was that they were not assembled competently and the other half can be attributed to design flaws and the use of cheap parts.

What makes matters worse is the total lack of customer service from Raidentech, which is the same company as Nitrorcx. You cannot contact them by phone at all since they will never answer your calls. They do not return emails at all. Why does it take two weeks to ship from LA to Riverside (60 miles)?

Finally, there are no replacement parts for the Blur - so don't waste your money.

You get what you pay for. Go buy a major brand from an established retailer that stands by their satisfaction guarantee.
