ASW20 tail tank mod

I want to have a tailtank in my ASW20 and I have heard there is one.
Where would I get the paperwork and plans for the mod.

John Murray at Eastern Sailplanes had a kit at one time. Finding the solenoid
switch may be a problem, but I think it is the same as a 12 volt lawn sprinkler
set-up. 6 quart for about 12 lbs. is about right. I would do a proper W&B after
installation and remember to dump it along with the wing water.

Oops, John can be found at

With my weight ! )))I don't think it will matter much if the tailtank
will not empty.
One of our guys with a Discus fills the tailtank even without water
in the wings,he has done a W&B and he is ok with
this amount of weight in the tail.
Saves his partners having to put lead in the cockpit.

I think it is a better idea to add lead to the tail to put the c.g. where
you want it without water ballast in the wings. Then use your tail tank to
counteract the water in the wings only. In this way you can drain the wings
and the tail and still have the c.g. where you want it. Draining partial
water in the tail and trying to guess at how much remains is inaccurate and
unsafe, especially when trying to keep the c.g. near the aft limit.
