Nozzle testing (again!)

I know I have already done this earlier on in the Blog but I wanted to do some final setting up of the proportional valve parameters before lift off. I wanted to make sure that open was fully open and closed was fully closed. There is a set up procedure that comes with the prop valve controller and certain steps you need to stick too to get it correct.





I used compressed air to simulate the fuel (it's a bit cleaner :) ) flow and all seemed to work fine.
