"This analogy sums it up pretty nicely. I bought a phantom 4 after about 4 years of building apm and pixhawk-based craft. My main pixhawk craft hasn't left the shelf since I got the P4. The HD video range of lightbridge is truly impressive. …"
"I suspect you will find the lack of a gyroscope and barometer to be a problem. Most full FCs these days are 10 axis."

"Thanks for doing/posting this. There's lots of new opportunities for compoent layout with that configuration.."
"Paul do you possibly have something connected to (supplying power to) USB port on the pixhawk? Battery failsafe won't trigger if the USB is connected."
"Alex - sorry if I missed this earlier in the thread, but are you using the latest version of MP? There was an issue that came up around -rc4 with the version of MP out at that time that was reporting 'false' EKF errors. As far as I know, everyone…"
"Well, three props were off the craft after the crash. Two had broken posts on the prop adapter, and one was just removed from an intact post, spinner nut and prop on the ground nearby and undamaged. Prop adapter post was not bent. I had assumed…"
"Thanks Rob. I'm accepting at this point that a loose spinner nut was probably the culprit

"Thanks guys; I think the most likely explanation at this point is a loose spinner nut, not software.
One of the props that was off after the crash had an intact adapter, spinner nut also intact but detached. I initially attributed this to the motor…"

"As as each member in a pair is applying thrust and torque in the same direction as its twin."
"Crash on rc4 - possible gyro issue?
I'm posting this log here in case it's useful, as there's been some gyro issues mentioned in Rc4, and the logs here show an anomaly in IMU.GyrZ before anything else appeared to go wrong. This is a 750-sized Y6…"

"Set parameter Wp_yaw_behavior to 1. The default setting (0) doesn't adjust yaw to follow the direction of travel."
"Guys, With all due respect, this discussion is inappropriate for diydrones.com."
"Re: b) increased accelerometer range from 8G to 16G to reduce chance of climb due to high vibrations (requires accel calibration)
I have a 250 which had some serious altitude stability issues on 3.2. Those problems seem to have disappeared after…"

"Interesting.. I didn't notice the GPS glitch. It was during a time when I was in loiter, quite a while before the crash. It was basically one record with HDOP=99.99 (the lat/long/nsats were all normal)
I've sort of come to the conclusion that…"

Hi all - I'm having a little trouble determining exactly what happened here. I was doing some initial backyard low-altitude hover testing of my new Y6B. This is a large 750 size sky-hero frame with 6S batts.Around log line 113630, one arm…
