Flight Session #16 - Nova flies first Auto Way-Point Mission

The Nova is flying great lately, so I'm trying to catch up with some of you. I also now have an Android tablet that's good for more than just monitoring Telemetry (with DPv1). I tried my first Auto Way-Point Mission, and it went fine. So, now this tops the list of the coolest things I have seen my Nova do since I got it.

It's also the first time I have flown with Droid Planner v3 (Tower).


The simple 6-point mission path is in green. The red path is Alt-Hold flying around as fast as possible (full-stick). I've got the on-board video and my brother also recorded the flight with iPhone. No gimbal yet, and nothing that interesting, so not sure I will upload (but nice to have none-the-less). There were people on the right end of field, so I didn't fly over them.

There was one strange event though ...
I had just cancelled a second Auto-Mission due to LowVoltageAlarm. I then pegged the sticks to bring it back closer for a quick landing. I started to fly fast (so I had some speed) and then the motors stopped and it was gliding through the air (but falling at like a 45-degree angle) with props stopped for a second or so. Pretty much freaked me out. Not sure how I recovered and landed it because I was kinda low.

ArduCopter 3.1.3 7-Apr-2014
Changes from 3.1.2
1) Stability patch fix which could cause motors to go to min at full throttle and with large roll/pitch inputs
------------------------------------------------------------------[/CODE]

So it seems that after about 35 flights (on v3.1.2) I've finally experienced the serious "Dead-Stick Throttle Bug" in it. Looks like I might have to re-compile and install a custom v3.1.5 after all.

I flew my Hubsan 107d FPV for few batteries at first. It was the first time I have flown it outside. It flew fine, but it was almost too windy for it. I also took it up pretty high, but it's so small, it's hard to see orientation (once it gets up there). I'll have to make a LCD sun-shield for next time. I also let my brother fly it a bit (he's just learning to fly quads). Another good day.
