Component weigh in for all parts is 468g. *Note you will not use all the parts, so the final weight will be slightly lighter (unsure of how much lighter - still building it) -

(#2) motor mounts on top -(#7,#8 are the 4 body brackets, #8 is the camera pod mount bracket, end caps as well as , #6 are the end caps, #4 are the boom brackets - NOTE there are brackets with holes in the curve - which I assume are for the motors -

#30 Bottom plate, #40 are the two top plates, #37 is a mobius mount, #34 are bumpers for the top of the quad. -

You'll want to start by assembling the boom brackets on the boom - these will be installed in the side plates. Grab parts 7 (3) and 8(1). Note: Part 8 is the forward camera mount plate and is a little thicker than the other 3 plates.
Big thanks to tfmccull for setting us up with our fancy new intro 
Trying to make out what these components are....
C1, C4, C6
C1, C4, C6
Should be obvious copper tape and some cat shielding does wonders quieting otherwise noisy systems, but for those of you without RF Explorers, it's impossible to quantify just how much...until now that is 
First a few things. I have on my bench
1) RCTimer MinimOSD v1.0
2) 3DR MinimOSD v1.1
3) ebay MinimOSD v0.1
I scanned all three and they all walk over the UHF control band. This in itself is fascinating because I was under the impression that recent versions of the MinimOSD board switched from Linear to Switching regulators. The Switching regulator options have options of switching at 550mhz, or 1200mhz, whereas the linear ones are just that. I have to check the schematics, but I didn't see any spikes in those ranges yet there is a significant rise in the noise floor up to 12" away from the unit.
Anecdotally, I've read across different posts that cpu processor clock cycles happen to coincide with the control band - only about -100db but still, it's noticeable. MinimOSD on the other hand raised the noise floor substantially within the typical distances of components on multirotors.
Anyway - I stitched together some scans...should be obvious which ones are which...Confirms obvious things we already know - like put your parts away from each as much as possible, but what's even more exciting is, how much copper foil tape dampens the effect

It's a lot of work to put these up in the air, but when it comes together...boy does it come together
Sit back and enjoy the ride.

It appears uaviation.net is no longer selling the kits...You can still download the files and get the boards fabbed yourself for like $15 at oshpark.com

I'm an APM guy, but I'd heard about the CC3D, and just like any other fabulous piece of technology - it's unavailability makes it just that much more desirable. So I was out on ebay just checking to see what the latest gougers were charging when I came across a rather peculiar listing - a Maker's kit for a CC3D.
It was just a PCB board with 2 pigtails. In the listing was a link to a bootloader and a bill of materials. You take the BOM and create an order with Digikey - and as everyone knows - 2 days later you get a present in the mail I'd seen the curious inventor's instructional videos on how to solder SMD parts but it's just like anything else - they made it look so deceptively easy. The good news is, it actually is as easy as they make it out to be but there are special tools and techniques that are necessary to do this right.
Mistakes will be made and you will need the right tools to back out of those issues (i.e. solder braid and flux to wick away solder bridges), but the trick to getting through is proper planning, the right tools and lots of patience. For anyone wondering - unless you have the equipment, this isn't even close to being cost effective - but that's not why I took the challenge. I wanted a neat project that would test my skills - and boy were they tested!
Anyway - enough...Continue Reading

Here's part 2 of the setup process. Some meticulous planning and a lot of test wiring harnesses resulted in a fully functional MinimOSD operating in master mode
