Oh ok, well I'm sure you will like what you bought...don't overthink it too much. Just remember your basic engine care, proper tuning, and you will be fine. Are you hearing this from local friends who have the same kit on their truck or something? Sometimes you have to take the good with the bad, and if anything let the negative comments lead to preventative care? If you are getting worried about this because of what random strangers said on a website you have got to remember, not everyone with the internet is an expert, or even a intermediate user.
You probably know well enough, if someone on this forum has a problem they are going to talk it out with other nitro heads to figure out what they can do to make it better. Sometimes factory flukes happen, that is with everything. A lot of the "I ran 1 gallon of fuel through it and boom" comments you see could be factory flukes, lack of care, stretching of the truth, etc...
Just remember, "I ran one gallon of fuel through it and it died" could actually have been more like, "I ran one gallon of fuel through it without ever letting it cool down during break in and it died after running 4 hours at 300+ degrees" or something like that, you get the picture.
Now, if you are at the track with your friend who you know takes good care of his rc and you trust his opinion, and while talking about how much he loves his truckzilla kit it spontaneously blows up on him maybe you would have more reason to be leary of the kit. Just saying...
