Sean 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. Jon 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 = else having this problem? What else should I check for? What is the expec= ted dump time for a 29? I use 6 minutes to be safe usually. 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= alve handle accidentally and not the wing/tail? Even if this was the 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, Sean |
