Okay, Here is the latest with the build. Rather than purchasing an additional motor mount for the GPS, I went to the local hardware store (HomeDepot) and purchased a wall clamp, it fits perfectly. I put 4 ESCs in top and 4 ESCs on the bottom of the base plate. Each set of 4 will receive...

I have to say my experience with eCalc has been similar, maybe I am missing something but every time I have used it, it didn't seem to provide useful information - maybe is it not setup well for multicopters.

Here is one I whipped together from the mar's rovers: http://web.me.com/marlo.steed/Ed4765/Mars_VR.html

http://www.uavproducts.com/camera-gimbals/ Looks great but I wonder if it can fit a larger DSLR?

Depends on the leds - I put my leds (turnigy) directly off my 45s batteries without a problem. I sense some can take this others probably can't.

My experience has been when you eliminate everything else - it is more than likely bad ESCs.

Macsgrafs, It looks like this stuff comes in different thicknesses. What thickness would you suggest for my application (octo 30A ESC)?

Yes, that makes it much clearer. However, shouldn't you have a camera onboard to be accurate? Thank you for the video.

Thanks for that suggestion - it does sound easy. I will explore that. Marlo

Actually that one is designed for an octo but seems questionable for a more powerful setup. If you used 2 then you would probably be okay.

I did get an email back from these folks - they rate this distribution board at 120A: http://www.kkmulticopter.kr/index.html?modea=vieweng&mc_selected=MultiCopter&sc_selected=Center&sn=power_board_octo&id_no=120 ...I am not not into electronics per se but if you multiply 30A ESC by 8 then that...

The Dean's power distribution connections are 57g with all the cabling attached. Here is the source: http://www.nghobbies.com/cart/index.php?main_page=product_info&cPath=1_10_141_142&products_id=539 Sebas, That does look pretty neat. You probably are right about more and more fail points...

I have been busy so not much progress on the build. However, here is my power distribution solution, I will put two of these in connected to two different batteries. I have used this before with my X8 with a hoverfly pro fc, it adds a bit weight but it goes together quickly and seems to work well.

I am thinking about a Jr or this one: http://www.spektrumrc.com/Products/Default.aspx?ProdId=SPM2800US The Spektrum 10t is suppose to be out in another couple of months and looks like it has some very interesting features for AP work.

Bowley, Nice stuff - Get creative put a logo overtop of the dust speck. That would salvage some good footage. Warmupper, really nice artistic work - very smooth.

Indeed one would think if a company was going to build a distribution board, that they would provide enough headroom for a heavy lift or at least have a HL model. Still looking myself, I may just bite the bullet and solder a spider arrangment.

xtakos, your link is not working.

Thanks Boris. I will look into using a motor mount for that. I am now concerned with your comments about the power distribution board. I was going to use two Photoship One power distribution boards but maybe the Amp limit on the board is too low? Do you think the MultiCopter one would be...

Any suggestions for attaching the GPS unit to the Droidworx booms? I haven't figured a way to do that yet.

I haven't had good experiences with HobbyKing ESCs 20A. I had an entire batch that were bad and one of my HobbyKing 18A ESC went bad on my quad - it kept flipping until I replaced it. My HobbyKing ESCs were not exactly the same ESC that you intend to use but when you put expensive cameras...
