Yes Staale, I found that without the valves and filter, I would need a lot less voltage to arrive at the 750 ml/min.

I just checked my GSU data from the last flight (12 min runtime):

Max RPM: 112600
Max Pump voltage: 6.00V

I still have the plastic UAT in my Viperjet with the P200SX in (but have just received a PST "baby bottle"), so far no problems with the running, although I can see some "micro bubbles" in the tube to the pump, but they are very short bursts, and they only occur once or twice a minute, so I don't think it will/is a problem in practice (I can NOT hold the throttle in on position for 1 minute anyway on that plane )

Regarding service from JetCat, I have had zero problems with that, I always contact Max Reinhardt, he is a very helpfull guy !

I have had a couple of my turbines to service, and it has never taken more than 2 weeks complete turnaround, (a P160SE took 4 days, a P60SE took 1 week, upgrading software in my 9 ECU's took 5 days), so always very satisfied !
