EMS has a factory scale water drop system in their new DG-1000 1/3 scale model. Wing tanks, and positive pressure dump. Eric Meyers (Greenville SC) outfitted his 1/3 scale Fox with a pressurized system using a 1 litre soda bottle for compressed air and a 1 gallon gas type can for water. It would dump the entire gallon in a few seconds. Quite impressive. The problem is you can't scale water, it never will emulate the full scale appearance.

Hi Doug Well I flew an ASW20 for years, the water ballast system is installed in the wings, ahead of the spar, they used blatter type bags, The plumbing went to the cockpit area, There you had your valves that the pilot could access,,, the dump tube either went out the landing gear, or they had a separate dump behind the gear. There is some caution to full scale gliders, You don't want to land with the ballast in teh wings,, To much negative load, due to a rough, or bounchy landing caused lots of stress on the wings.. I don't know if this would be true with models, They seem to have stronger wings than scale.... hope this helps charlie RCSE-List facilities provided by Model Airplane News.
