Coolant Tank Mod

This was something we didn't know about until
we took the ship to John Spurling to have him go over it.

Seems these tanks have a problem with cracking

on the sides where the mounting ears weld on the tank from the flexing the frame does in flight.

John had me drill the mounting bolt holes out to about 3/8 of an inch and install rubber grommets allowing the tank to have give in it thus preventing it from happening. I noticed when Mark Wolf had trouble he came up with some pretty neat grommets which I like a lot better than what we have. Someday when I get around to it I'll probably copy his idea on our ship.
