Yup, that's the way to do it. I mix up a fairly strong solution of food
coloring and water and dump ballast to be sure nothing gets on the fuselage or tail wheel area. bumper "Andy Blackburn" wrote in message ...

FWIW, I have had the rudder off the hinges and the tailwheel out of its
bracket. No yellow stains anywhere. The rigid tube is sticking at least 14" below the belly of the aircraft. I especially like not having to wear a catheter, yet still having a positive seal.

The amount of extension needed may vary from glider to glider. 8" has proven sufficient on my ASH 26, and that's short enough that I can just retract it until flush, and not have to remove it entirely. The bulb just lies off to the side, so I don't have to find a place to store it, and it's bit quicker and less distracting to use without the need to insert it first. -- Change "netto" to "net" to email me directly Eric Greenwell Washington State USA |

I use the "tube-within-a-tube" model with good results:
- Two different diameters of semi-rigid polyethylene tubing - Outer tube glassed into fuselage bottom (turned a small flange out of thin plywood steamed to match curvature of fuselage, epoxied tube into flange, then glassed whole thing into fuselage - just to be sure) - Nested (inside) tube can be extended about 8"-10" into slipstream - About 18" of flexible rubber tubing connects inside tube to catheter, allowing you to stay "hooked up" for the entire flight I had the rudder off this fall for some tail ballast mods, and there is zero corrosion on the tailwheel or rudder hardware. Same for the main gear. Plus, it drains completly due to the orientation of the tubes (ie. no sags to promote pooling). Only trick is to remember to retract the tube prior to landing. Otherwise, you get a literal demonstration of the term "stepping on it." P3 (or should I say Pee3) "Andy Blackburn" wrote in message ...

look at my web page (copied from Aeox)
http://www.wingsandwheels.com/page35.htm and the flow charts for even normal constant flow systems (using Oxysaver cannulas) will show you over 46 hours usage at 10,000'....and over 25 hours at 15,000' all without using any electronic devices....the advantage (small) of the EDS is that you don't need to set the flow rates manually to get these higher durations.but the simple and reliable constant flow systems cost under 1/2 as much as the electronic systems and are simple and can easily fit all the components )(less bottle size of your choice) into a large sandwich bag! tim Please visit the Wings & Wheels website at: www.wingsandwheels.com "Eric Greenwell" wrote in message ...
