Aside from the fuel tubing with the clunk not being installed all the way on the nipple from the factory, there are no known issues with the tanks. We have customers with many gallons on their stock tank and still going strong.
That's not to say we won't be looking at the tank if more people have issues. But as of right now there are very few isolated incidents.
I also had a problem with my fuel tank cracking/shattering. I had just over my first half gallon of fuel through the kit, just post break in at the track for the first time when it happened. I ran two qualifiers and in the 2nd minute of the MAIN it seems that it cracked. I didn't have any type of hard crash or landing, however I am a nitro newbie and I will lean on the side that I might have had the tank screwed down too tight, not sure. I have already purchased my replacement, but I will pursue the warranty to have another spare in the event I have any issue with the tank.
My local hobby shop owner which has over 20 years of nitro racing experience did mention that he has seen issues with tanks from other kits that use similar "clearer type of plastic" versus "the less transparent plastic". He mentioned that with the clearer plastic he has seen similar cracking issues in regards to chassis flex and that the "less transparent" do not have the same issues. I realize that is not very scientific, not sure what the different chemical make up of the plastics are, just using a way to describe what I was advised based on his experience. If you look up for example the Losi tank, it is made of "less transparent" type of plastic.

As someone else mentioned in the forum I plan on doing some research to find out if another tank will fit the kit. I think the Losi is very close. As soon as I find something, I will share.
If there is indeed an issue with the tank, I have full confidence that Tekno will address is it correctly and remedy the issue to current and future NB48 owners. Tekno has a great reputation of standing by their products. Thanks for the warranty link.
