Andrew Brown replied to Jared Reabow's discussion Elevator servo twitches 3 times then gimble starts working.
"Not an expert but think this is perfectly normal.

Andrew Brown replied to x-air71's discussion PID settings for HK FPV (arduplane)
"I tried to use this airframe, but it was terrible... 

APM default settings are a good starting point, but i found even with a decent motor and 4s battery, this plane was under powered. Its heavy even before you start loading it up with gear.

Very frustrating..

Im now at a loss as…"

I have done an erase, reset, reinstall of MP, updated firmware.

Run radio calibration, level and compass, all pass as expected.

Andrew Brown replied to Wesley Versfeld's discussion AC3.0.1b horrific damage
"Can you download your Wife's LOG files...
Without them its very difficult to see what mode she was in when the damage occurred...

Maybe she breached the GeoFence and entered RTL...?

(sorry trying to make light of situation..But hope you can repair)"

"Just to add my 2 pence worth when it comes to testing failsafes.

Its one thing to turn off your Tx when on the ground testing but I would never to this with a model in the air. APM or not!

The way I test Tx Failsafe is to set the end point of my…"

Andrew Brown replied to Dean's discussion Hexacopter crash. Please help!'
"Correct me if im wrong, but if your APM is tuned running off a 3S Lipo for all the PIDS and then you plug in a 4s, its going to be much higher powered and will require FULL tuning before flight.

I certainly know that the 1 time i tried switching…"

Andrew Brown commented on Kevin Hester's blog post Droneshare now warns about suspect parameter values
"This could become a great way of sharing PID settings..
Think its a great start, next step should be to show the value ranges where a parameter is outside it..

i.e. LOITER_LON_D my value is 0.015 which showed up in red.. but why, it is too high,…"
