Wow, had to go through thsi thread today.

For the forst time in my R/C Turbine experience I am having problems with bubbles in the UAT. When I fill up the tanks, the bubbles are virtually non existing. After about 30 seconds, I notice that the UAT is about 1/8th empty, that'a a lot of air. The lines coming in from the main tanks Tee is pushing virtually pockets of air.

Anyway, I always thought that the UAT would fix issues like this.

Question, I have my UAT in a horizontal position with the fill and the vent nipple on the side facing 45 degrees up. It is a Hanson trap. Is the sack inside the tank supposed to be horizontal or vertical (as in when you rotate it with the tank sitting on it's side). Does it matter?

I'm also skeptical about using large size tygon tubing. I'm changing to a smaller size and will be safety wiring all connections.
I missed a really good day of flying today.
