pours into the fuselage. I'm now sure that's where the water in the
fuselage came from.


Bill,
I went through the same drill with my Nimbus-3. Fixed everything, but on
each
landing, I would have an inch of water in the belly. Finally found it was
caused by dumping with the gear down. The 2 wing dump valves are located
in
just the right place to feed a vortex shed by the lowered gear and the
vortex
sucks up some water into the wheel well. Sounds far-out, but I stopped
getting
any water in my fuselage when I started dumping with the landing gear up.

Now that's interesting. I'll give it a try.


My Nimbus had springs inside the wing and also on the dump shaft.

With the external spring removed, there is no evidence My 2C has a spring
inside the tank. The shaft rotates easily and just stays where you put it.
With the spring installed, the valve closes with a fairly light force. I
have to grease the valve and pull it closed with the tail assembly tool to
prevent leaks. I may make some springs with 1/16" piano wire to replace
the 1mm wire the original springs were made of to get a little more closing
force.
