It's worth checking the deflection of the "paddles" that push the dump
valves and auto-connect as you push the wings in while rigging. Mine was
dumping at different/asymmetric rates and that was the root (pardon the
pun) cause. It's an easy adjustment to make.

This has been a problem since late this summer. Asymmetric and or slow
dum=
ping.

After having the valves open today for (guessing) 20+ minutes (to be sure
i=
t was dry) I landed to find the wings with significant water (10-15
gallons=
a side) still on-board. Water flows thru the outboard panels so they
are

clear. The valves seem to be opening fine on the ground. We checked the
o=
uter panel for flow carefully this am before flying. Water flowed thru
eas=
ily when the full wing was lowered slightly.

This is quite a mystery. It cost me significantly today. I thought I
was

empty but was still well over 10 lb/ft I'm guessing by the amount of
water
=
still in the wings when I had landed. It took 5-7 minutes for the water
to=
dump AFTER I had landed.

Any ideas on what could be cuasing an excessively slow dump cycle?
Anyone

expec=

Maybe I was perceiving actual dump time wrong (need a stopwatch)? Maybe
I

thought only 3 minutes was 10-15? Maybe I was my using the fuselage tank
v=

case
=
it was 7-10 minutes from my last "thermal" to the ground and the water
was

flowing fine out of each wing valve when I landed. So the right valve
hand=
le was opened at this point. This should have emptied the wings alone
easil=
y, to say nothing if the 10-20 minutes the valves were open in occasional
d=
umps before that point.

Thanks in advance for ideas...

Sincerely,
