"@R_Lefebvre: "Not to mention, from what I've seen, the systems that can't output PPM Sum also don't have an effective failsafe scheme.  So why would anybody want to fly that stuff?" Maybe because one would not want to…"

"I would like very much to see what that Atmega328 on this IMU is doing. Where can I find the source?"

"Yes, there are no camera mount drawings yet. I would like to know if they will ever be published?"

"I thought Aducopter is opensource, but I don't see the published plans for this mount. Is there a change of policy?"

"@Melih, It's interesting that there are no really good opensource camera mount designs (like the one you've used). All available have many flaws."

"Is that mount design opensource?"

"Perfect idea to design the mold and mass-produce the shroud. Many people will be interested to experiment with this, but they have no mean to easily make the shrouds themselves, and would like to buy one especially for standard 10" props."

"Delrin is crazy expensive. Better to buy the CNC'd polycarbonate parts from jdrones."

"Any thoughts on Delrin? I assume its heavier, but at least its durable and Ponoko offers that material (3.2mm is closest thickness) ."

"Jani,   Can you please clarify which parts are made from acrylic and which are polycarbonate from this list: Dome arch, Dome center lower, Dome center upper, Motor mount lower, Motor mount upper, Landing gear fin   Thanks."

"Original files were made with ArtCAM/SolidWorks and it seems that it inserts some extra strings on beginning of the files. AutoCAD, Google Sketchup and many programs opens those without any problems.   Only few parts are made from Acrylic. Most…"

"Thanks for the link, have no problem with the files on on the link you provided.  "

"Those DXF files in ArduCopter repository are known to be problematic, a lot of tools can't open them properly. You have them opened/saved again as DXF and PDF on this…"

"what's the weight of the material ???"

"Wondering what program was used to create the DXF files at code.google.com.  ViaCAD Pro and VcarvePro cannot load them.   thanks  "

"Please note that the real kit parts are made out of polycarbonate, which is much less brittle than acrylic. Unfortunately, Ponoko doesn't offer that.   My experience with the acrylic parts is that they will break with pretty much every…"
