Get some "bilge" tubing (the white, flexible plastic stuff that looks like
trachea tube) and stick in the water dump holes on the bottom of the wing
and run it to a home-made manifold on the fan.


I have a similar system for my Diana wings. I used flexible plastic
tubing, about 1-inch OD in 6-foot lengths with integral end fittins.
It's available from U.S.Plastics in Lima, OH.
