In many of the posts here I see pattern models with things I think I'd like to use myself. One is the neat looking pipe mounts, short and long. Those I've found at hobbynet online.

There's a few others I'm not sure what they are. One is what looks like a check valve held down by some sort of black (Carbon)? V looking thing that wraps around a check valve with a single screw. What is the check valve for and who makes that hold down piece? Is it a vent valve for the tank? Do they run a line outside the aircraft? The next is the "One Touch" cowl/belly pan hold down system, how does it work? And lastly They use some very nice looking model holders that look to be very long with folding aluminum fuse and wing holders. These I've no clue where to find, home made maybe?

Most everything I'm curious about is here.

Anyone know if these items are available in the USA?
