Introduction

Coming from an RC sailplane background, the task of planning system wiring on a multirotor can be a bit daunting.  With sailplanes, all one has to deal with are servos, rx & battery; with multirotors, and in particular, this one we have:

Not to mention all the components that will be on the camera gimbal!

So, if you’re like me ( and hopefully you’re not! ), one spends a lot of time just standing and staring at all the components, pre-organizing how all the components will be arranged on the airframe.  That is what this post is all about so let’s take a looks at version 1 of my center frame components layout…

Component Mounting Philosophy

One can get caught up with trying to hide as many components and wires as possible for a clean look.  My approach is to provide a clean installation while still giving quick access for key components.  Really, unless one is trying to develop a water resistant / proof platform, there is no need to hide components that you would otherwise need quick access to.

Frame Considerations

As stout as GD’s frame are, they are surprisingly light which is great as at the end of the day, a lighter MR stays in the air longer.  Much of this is due to all the lightening holes in the carbon plates which is great also for giving you plenty of options for wire routing.  My only concern is that there are not solid slabs of carbon to mount the IMU or GPS.  As you know, if the IMU were to come loose, you’re nice day of flying would turn into a sad night of weeping!  That said, there is probably sufficient material for the double sided tape to adhere to.  Just to be safe, I’ll be adding additional points of contact either with zip ties, velcro straps and/or dabs of hot melt glue.

Baby powder isn’t only useful for baby’s backsides! Sprinkle some on the back of exposed adhesive tape and rub in. Blow off the excess and you’ll have a smooth nonstick finish!

Another nice thing about this frame is how quick it is to assemble.  It does have a bunch of screws as some have pointed out in this thread but not any more than I personally find reasonable.  A nice touch is that there are pass-through holes for your allen/hex wrench where needed for frame bracket screws and such.

Telemetry

Spektrum TM1000 Telemetry System

TM1000 Hidden in Landing Gear Support

Even though DJI’s iOSD Mark II provides voltage telemetry to the one looking at the camera, I’m often finding myself yelling to the camera operator (Phil in this case!) “What’s our voltage?!”.  For less yelling and more peace of mind, I’ve decided to run telemetry via Spektrum’s TM1000; specifically pack voltage and temperature.  I’ll run the temperature sensor first in the arms to make sure the ESCs aren’t getting too hot.  Later we may monitor the temp of other components such as batteries.

As you can see in the picture, the TM1000 fits perfectly in one of the landing gear supports!  I simply wrapped it in foam and slid it in for a no-slide fit.  The wires then have a perfect exit point right at the center of the frame.

In Closing

Instead of waxing poetic on the rest of the instal, I’ll let the pictures do the “talking”.  If you have any questions, comments or suggestions please feel free to add them to the discussion below!
