A quick update...

Currently in the passenger seat of the car on the way home.
Just spent 4 days at FAR camping. Worked on three things...

1)Navigating Pad to Pad flying the exact desired LLC profile with the helicopter, and new GPS system. This work went very well, many exactly repeatable flights, only one scare the GPS needs more voltage for proper operation than all the other electronics, so one flight the system battery was low and even tired, sun burnt and sleep deprived at dusk I mangaged to save the helicopter by taking over.

2)We had a very poorly timed large project for a customer. It was the largest rocket ever fired at FAR and the test went really well. Can't really say more.

3)We tyried to hover the silver ball. We got the altitude stuff under controll, but never managed a stable hover. Nothing we did in the way of loop tuning seemd to help. Got up before sunrise this morning to carefully look at everything in the system. I did some sweeps of the gimbal actuators trying to precisely measure dead band and hystersis. Came up with a sequience where the actuator moved OPPOSITE of the commanded direction. This jives with observations and as we would hover then just all of a sudden flip over to the abort limit. Seems to come and go depending on how I press on the PCB, I had no replacement with me so it means going home.

My son is in the middle of starting a new business and has other commitments for most of this week. I've got business commitments Monday and Tuesday, but I hope to go out to the site
Tuesday night for more testing. We will be short handed so if you are in the So cal area and don't mind hard work in the sun at a site with no good shelter and no running water we could really use some help.
