Notice: Much of this quad was assembled from parts I had laying around. While there is nothing inherently wrong with any of the selections, If you wish to use this build as a template, I would advise researching your potential options. Particularly, the Paragon UAV motors (no longer available for sale), and the VGood ESCs (just get some BLHeli/BLHeli_S based ones instead).
Winter is here, and that means finger numbing cold and short dark days. It also means that after my daily tasks of "responsible adulting", there isn't enough daylight remaining for any real flying. In an attempt to gain as much flight time as possible, this build grabs Old Man Winter by the throat and squeezes...
Night Vision: Well... as much as possible at a reasonable weight and cost. Ideally, illumination from the stars will be sufficient, and additional lighting sources, such as parking lot lights will not be required. While the RunCam Owl and Foxeer Night Wolf are both excellent low light cameras, they are not suitable for this task. Currently the only option potentially capable of meeting this objective is the RunCam Night Eagle.
Durability: Regardless of the effectiveness the camera, flying in total darkness is still going to result in less than ideal visibility. As such, I anticipate increased attacks from ninja branches and various other gremlins. That means crashes... more of them than usual. Elemental RC's Pyro frame was selected for its stiff mono-plate design, high quality unidirectional carbon construction, and.... well... I had one sitting around, so it fits the bill perfectly.
LEDs: More crashes also means more searching for a lost quad. While a buzzer is useful (and included with this build), it would shortsighted to not equip LEDs and turn the entire quad into a glowing search beacon. Also, TRON and acid flashbacks seem cool.
Although I am not sure which version of the RMRC Dodo flight controller I used, it was older than the Rev.b listed above. That being said, I'm not aware of any breaking changes that could cause issues between versions. If you opt to use the Dodo, be sure to buy from a legit vendor as the clones of this board are known to have problems.
Unlike the HS1177 series cameras, the RunCam Night Eagle does not have the ability to display a call sign. To accomplish this I instead opted to use a Seriously DOGE OSD running MWOSD (which is either a good thing, or a bad thing, depending on who you ask). While this board makes for a really clean build (connecting directly to the flight controller using pins), it's a difficult product to recommend. In comparison to a standard Micro MinimOSD it's expensive and quite large. Additionally, there are now many other OSD options available that are capable of fulfilling multiple functions within the same footprint of the Seriously DOGE board.
The LEDs require a 12v input. I used a Pololu to step down the battery voltage and ran this to a small switch on the PDB. If I need every last drop of the battery for flight performance, or I'm just out day flying, the switch is used to turn the LEDs off.
Awesome attention to detail in this build, love the look of it. Great photos and a well written up build too! I have a couple of questions:
Ultimately, doing any of this "water-proofing" adds an additional steps to any rework that may later be required. The nice thing about conformal coating is you can basically just use your soldering iron to burn through it. Hot glue and liquid electrical tape both require more work as you have to peel them away. That being said either method provides more protection than nothing, and, if I am working on the pdb it usually means I have had to disassemble the entire quad anyway. It's really up to the you what's worth it and what is not.
AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

How do you like that OSD from RMRC? I have a DODO FC and looking for a good OSD to add to my build.
Well... it runs the same MWOSD firmware that the MinimOSD hardware also runs, and while it is currently on sale for $55.99. This $7.99 option runs the exact same firmware. That being said, it also provides a couple 5v/12v step downs, which are basically the same as this and this. In addition it also provides clean power for your video which is what this LC Filter also does.
As you can see the exact same functionality can be accomplished at a much cheaper cost. What you are really paying for when you buy the Seriously DOGE OSD is a single package for all those functions that directly integrates with the DODO FC with no wiring. Another thing to note is that because this board is directly connected to the top/bottom of the FC it does make the overall stack quite tall.
In short, if you want a single all in one package that cleanly connects to the DODO FC, and cost isn't of concern then it's solid choice. However, if you do not fit this criteria exactly, then its a tough board to recommend.
As you mentioned having a DODO FC, this may be the right option for you. If you were still in search of an FC I would suggest looking for one that supports the Betaflight OSD. I personally prefer it, and feel it's implementation is cleaner and easier to configure. (Although, I have heard a new version of MWOSD is currently in the works, with many improvements) A couple boards I would recommend would be the Betaflight F3 board, or the Omnibus F4. Hope that helps to make your decision. Cheers!
