Progress and thoughts...

I flew the helicopter in attitude hold mode today.
It worked perfectly. the autopilot flys a lot better than I do. On flight #2 the commercial off the shelf RC regulator failed and the servos acted very erratic.I set it down with no damage. More debugging Sunday.

My son and I spent the day at FAR, we went out to clean up our storage space, work on the site and watch a large 5K liquid test firing. The work on the site is the real sexy part of rocket development. I spent my morning repairing the outhouse door jamb and installing godzilla's own door closer. Maybe the Mojave winds wont rip the outhouse door off, again.

After a full day of checkout the large test was a no light with a frozen LOX valve. We were not involved other than as spectators. My son has been working with some people doing peroxide rockets of various forms,and the grass on that side of the fence looks a lot greener.... Use cheap nitrogen for a presurant gas, all your valves and plumbing are at room temperature, dense, reasonably clean. Possibly auto igniting in bi-prop mode after decomposition.... hummm....
