Tonegowa Servo Success...

Tonight I tested a valve based on the tonegawa PS-050 servo. It's 890 grams and seems perfect. I'm posting a video of the 350 PSI LN2 test and it works really well. The video is at here. The mechanical set up for the tested valve had a few issues. So my son built a second valve based on the Tonegawa it is 781 grams and works just as well. I think we have our first flight weight bit of actual XPC hardware.
