After many many flights with my JC Titan, i finally had a flame out on take off. Not good[

]
I tracked it down to the UAT's festo fitting that feeds the pump. Above 1/2 throttle it would suck in air. Im solving the problem by ording all new UATs for my planes that are high volume and that have BARB Fittings
Oh yes, that urethane tube gets old, it changes shape and then the blue fitting gets loose, especially if there is a bend in the line as it leaves the UAT. I have seen this several times!
