I've got this Kevlar tank, but to be honest I was going to send it back and order a different one. The reason I wanted to go with a Kevlar tank is to minimise the risk of a post crash fire. But looking at the design of the tank the lid is just butt glued onto the rest of the tank and so doesnt really offer much strength.

...but, one possible counter argument is that its better for the tank to shatter and spray the fuel everywhere, this will then flash burn very quickly and cause little damage rather than a tank that survives most of the impact but then leaks a puddle of fuel in the plane which slow burns and destroys everything.

What do people think about turbine fuel tanks? Strong or weak?
