Got some more work done on the fuel tank too.
I was lucky enough to score a Fiji water bottle in the 360 mL size - they're pretty hard to come by. I ordered the cap a while back, along with some Viton tubing and a felt clunk.
It's important to ensure that the clunk doesn't snag on the bottle in any attitude.
I also cut some foam pads to cushion the tank inside the fuselage. For the front of the tank...
...and beneath it.
