Heya Piper

Just came across your build - it's looking good.

Don't know if this comes too late but when I was building my GP Skybolt a few months back I ran across the same issue with the tank not being accessible after completion. Sooner or later all the silicon lines will need replacing and murphy's law being what it is, it'll be the ones in the sealed up tank compartment that let go first. I came across a thread that offered a nice solution to this - remove the brass tubes that come with your tank and get a length of copper tubing long enough to run from the inside of the tank all the way out through the firewall. You can see some shots of this in [link=http://www.rcuniverse.com/forum/m_5070795/mpage_2/key_skybolt%2Cbuild/tm.htm]this thread[/link] on page two, down near the bottom dated 12/18/2006.

Hope this is of some use to you, though at the way you've been rocketing through the build it might be flying by now!
