David Pulvermacher replied to Hugh's discussion APM 2.8 and GPS / Compass
"Found this:
If you have a 2.8 with external compass do not use the 12c, plug it into the plug under the GPS plug and you have to remove the jumper to the right of the GPS.

David Pulvermacher commented on Jared Reabow's blog post How to Get APM/Pixhawk telemetry on your taranis!
"Hi All...
I've just wired up a Teensy LC (having flashed it using arduino as above) to Rx line on my Minim which is working perfectly, and the Smart port on the X8R.The teensy flashes slowly during boot, but then flashes rapidly thereafter, with no…"

Is there any reason why one cannot add four pushers to a quad using just four escs to control all the motors?I know that there would be no redundancy with that configuration, but there is an advantage related to lifting capacity...Anybody any experi…

Does anybody know whether it's possible to activate retractable landing gear using the barometer/GPS with Pixhawk?I'd like to have my gear automatically switched into the down postion at say 5 metres above the ground when landing....Thanks. DP

David Pulvermacher replied to Marco C's discussion CAN NOT INVOKE AUTOTUNE FLIGHT MODE in ArduCopter User Group
"Why dont you just allocate a switch on your Tx to channel 7, and set that channel in MP to Autotune?
You just need to set your end points to that channel so the when the switch is activated, the PWM is over 1700...
Then fly your craft in Althold and…"

Can the Teensy LC from Sparkfun be used instead of the Teensy 3.2?"

David Pulvermacher replied to Flak's discussion Quadcopter - APM v2.8 not recognizing throttle with ESCs plugged in. in ArduCopter User Group
"Flack, unless I'm very much mistaken, you can't use 3.3.3 with the APM.
I think 3.2.*? is the last version that was supported. Perhaps you should try installing ealier firmware, and start again?"

"Not so Gerhard...
I'm in Cape Town and I'd very much welcome a chat!
I've reverted back to my APM 2.6 on my 550 cannibalized frame, as I've had issues with my RcTimer Pixhawk clone, which has been sent back for evaluation.
Drop me a line:

I've had to go back to my APM 2.6 as my Pixhawk is faulty.I tried doing an all in one ESC calibration bit the APM will no go into calibration mode.Could this be due to the Rx/ APM being in CPPM mode?

David Pulvermacher replied to Rob Summers's discussion SRO parameters in mission planner for pixhawk in ArduCopter User Group
"Thanks for that Paul...
I guess my question is whether the default settings for Copter 3.3.1 will enable telemetry from both Telem port 1 for the 3DR radio, and from Telem port 2 for the MinimOSD.
I have set both to the settings described on the Min…"
