Hi folks,
Had a BBQ this weekend which was struggling to get going. "How can I fan the flames" I wondered. I looked over and saw my quad sitting on the lawn :D...

"Thanks Crispin. That's been very handy! Quick question - what did you set as the throttle failsafe value in the settings? Did you leave it as default? (I think mine was 917)."

I think there was already a log raised for it but it was a low priority.

Rick Eis commented on Crispin's blog post Spektrum DX8 and AR8000 Failsafe setup"Hi Crispin,
You said, "An idea might be to only enter failsafe if armed AND there is movement in the sensors (i.e. you;re in flight). Will add a note to devs."
This sounds like an excellent idea .... Did you send…"
ootktk commented on Crispin's blog post Spektrum DX8 and AR8000 Failsafe setup"I thought of this last thursday but didn't implement it that night as I don't usually fly out of range. On friday I flew behind some telecommunication tower at close range and the inteference caused a signal loss when it was out of LOS,…"

Crispin commented on Jason's blog post Open-source ESC - is there a potential community?"Would adding weight out at the motors not make it sluggish to respond? All weight needs to remain as central as possible.

Crispin commented on Jason's blog post Open-source ESC - is there a potential community?"my 5c:
It would be very cool if there was something purpose built for this. As some others have said, if these could be modular in a way.
An idea I've been playing with existing ESCs is to solder the pads on the ESC to a custom-made PDB. You…"

Hein du Plessis commented on Crispin's blog post Spektrum DX8 and AR8000 Failsafe setup"Brilliant, makes so much sense now that I understand.. Thanks Crispin. I'm flyinf Arduplane, I don't seem to have a THR_FS_ACTION. Setting THR_FAILSAFE to 1 or 2, just causes it to go into CIRCLE mode, how can I get it to RTL?"
Crispin replied to Jill's discussion Remove motor shaft on DIY Drones Motor AC2830-358, 850Kv"Remove the circlip under the motor and pull the shaft up. The motor will come apart.
Undo the grub screw in the top of the motor housing and pull the shaft out. Might be a tight fit."

Spektrum DX8 and AR8000 Failsafe setup

I've been struggling to understand how to get the APM failsafe working properly and have yet to find some clear instructions that a noob like I can follow. It suddenly dawned on me how to get it all setup.
Here is my normal zero throttle output:
Here it is when the radio is off:…

Not being overly chuffed with the battery mount on the 3DR and wanting somewhere to mount a camera, I decided to make another layer to the quad. A third plate below the quad seemed idea.
I fished out a scrap of unused fibreglass PCB I had in my goodie box. I took the quad apart to get at the bottom plate to copy as a template.
The normal plates have a series of 3 holes in the middle of each edge which seemed a perfect option to mount stuff. I…

I added very bright LED headlights to the quad a while back a) to freak the locals out at night and b) to help with orientation when the quad is far away. These are 12V LEDs and run straight of the 3S lipo. All was well....
One thing I don't like much is the rather small and dim SMD LED to tell me when the motors are armed. Mostly…
