Unreasonable ups and downs

Paul Breed reports on a pinhole in the "main tank" for the Level II Silver Ball vehicle: Progress ,... - Unreasonable Rocket - Oct.27.09

We patched the tank on the blue ball after a hydro failure, we will look at patching this tank in the AM, but 95% sure it means no 180 for us.

I''m confused about his fuel tanks because earlier he said they had replaced the main tank with a composite tank and on Twitter this evening he says that the

New composite fuel tank passes hydro!

Here is a picture of the composite tank.

Update: Paul says in the comments here that it is the H202 oxidizer tank that is aluminum (and has the pinhole) while the fuel tank has been replaced with the composite tank.

We still have an aluminum oxidizer/peroxide tank, we just replaced the fuel tank with composite.

Hi Paul,
Thanks. Good luck with fixing the hole.

what was the cause of the pinhole?

As I read Paul's posting, it was caused somehow by the grinding off of the "unused tabs".
