"Hello- awesome work- THANKS! I get the telemetry values sent to my Taranis- but the LUA Skript does not start up. I made the settings above /thank you for the screenshots!) but have no clue what the folder structure on the SD card has to be…"

"Hi- I think using a radio with telemetry is really helpful here, too! (Monitor Voltage / consumed mAh if possible) Greets"

"Hi- Perhaps this code could additionally be implemented in the Teensy to save the additional Arduino? http://openrcforums.com/forum/viewtopic.php?f=84&t=4539 Have a nice weekend"

"Hello- I just was wondering if somebody is working on implementing the SBus to Sum PPM into the Teensy. This would be awesome because it would save a lot of wiring or another arduino.., Perhaps there is something I could help to do so? I m not good…"

Roman R. replied to Rolf Blomgren's discussion APM MavLink to FrSky X8R S.Port converter
"Dear Rolf- this is incredibly awesome! That's what I was looking for all the time... More awesomeness would just be possible if the Sbus to PPM Sum also could be included because the processor should be up to the task (I am sorry- MY…"

"Hi Randy- Thanks a lot! I know that the impact is really small.. But- I am prototyping a medium weight X8 at the moment (5kgAUW) and for this reason still have the choice for optimal positioning! So- MPU6000 in the center! Thanks a lot…"

Randy replied to Roman R.'s discussion APM 2.5 mounting MPU 6000 offset relative to APM board in the group ArduCopter User Group
"Roman,      This question (or something similar) is asked quite a bit.  I think that you're right that ideally the MPU6k should be placed exactly in the center-of-gravity of the vehicle.  I believe the downside of…"

APM 2.5 mounting MPU 6000 offset relative to APM board

Hi-I am wondering if the arducopter SW calculates the offset the MPU 6000 has relative to the middle point of the APM 2.5 board?If not I would rather mount the board in a way that the MPU 6000 is in the center of gravity / center of motor diagonals and not the center of the APM board- correct?ThanksSee More

Roman R. replied to Randy's discussion AC-3.1 autotune support discussion
"Hi- Does your PPM SUM also just contain 6 channels? I have been using the PPM SUM of a 4 channel receiver successfully- but it has 8 channels in the sum signal, so I could choose CH7 to invoke autotuning. I am not sure what you can do if you just…"

"OK- SimonK FW: awesome! Arducopter 3.1: awesome! Thank you for all the developers hard work- do not worry about some of the comments! The so called "cogging" problem is not new and using leading edge technology CAN cause problems I guess…"

Roman R. replied to Randy's discussion AC-3.1 autotune support discussion
"Hi- interesting find. I would expect hearing this that there actually are quite a few people around flying a setup (Bat/Esc/Mot/Prop) that potentially has a "cogging" problem with extreme throttle changes! (Caused by flight controller…"

Roman R. replied to saba's discussion HexaCopter Electronics Help Required in the group ArduCopter User Group
"Hi- And good luck with your ambitious project. You should search for similar projects and see what they have used. I agree though that you should start with a smaller project when you have no xperience. The bigger the copter the more expensive are…"

Roman R. replied to minhaj's discussion antenna slection in the group ArduCopter User Group
"Hi- I am not sure what you are referring to? If you want a setup to do 5km FPV flights there is (thanks god) no "out of the box" system capable to do this afaik. To build you own setup that has this range I would suggest you do some…"
