That's great to know. My friend is experience same UAT bagging in his Euro with Titan engine. I check the fuel sys and all the lines are 6mm. It never happen before but the UAT had lots of flights there. Same thing with this Rhino powered L-39. Wish only flew one time for the maiden at time of delivery.

Oliver, what about the old center pick up tanks? There are few guys that never an issue using them. Rounded bottles are less susceptible to collapse and can be find in more rigid plastic.
