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.
Sounds like to me you didn't pull it apart and make sure all the gear mesh is correct(tranny & diff). But I see your point as it being a RTR nitro kit. You shouldn't have to take everything apart to make sure the factory did their job and make a quality product. But I have found that it is best to tear it down and go over it. Also shimming the dogbones will prevent the binding and the bending. I made the mistake of not doing this the first time and I learned from my mistake. Trust me, I have a SH .12 engine in a truck using the same 1/16 setup and the power is far from the stock .05 or .07 engine. And it holds up good.

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.
Sure there are replacement parts. I don't know where you looked for parts at.... They are everywhere. You can order them from nitrorcx, allaboutfunhobbies, redcat, himoto, ect.....
You don't have to buy a major brand to have the guarantee satisfaction...
